Radical polymerization of trifluoromethyl-substituted methyl methacrylates and their application for use in pressure-sensitive paint was written by Obata, Makoto;Asato, Ryo;Mitsuo, Kazunori;Hirohara, Shiho. And the article was included in Journal of Polymer Science, Part A: Polymer Chemistry in 2014.Formula: C7H6F6O2 The following contents are mentioned in the article:

Three CF₃-substituted Me methacrylates (MMAs), 2,2,2-trifluoroethyl methacrylate (TFEMA), 1,1,1,3,3,3-hexafluoroisopropyl methacrylate (HFIPMA) and nonafluoro-tert-Bu methacrylate (NFTBMA), were polymerized by conventional radical polymerization to give oxygen-permeable polymers for application in pressure-sensitive paint (PSP). The radical copolymers of styrene with TFEMA, HFIPMA, or NFTBMA were carried out to examine the effect of CF₃ groups on the polymerizability. The e values increased in the order of MMA (0.40) < TFEMA (0.76) < HFIPMA (1.19) < NFTBMA (1.31). The homopolymers of TFEMA, HFIPMA and NFTBMA (PTFEMA, PHFIPMA, and PNFTBM, resp.) were examined as polymers for use in PSP using 5,10,15,20-tetrakis(pentafluorophenyl)porphinato platinum(II) (PtTFPP). The PSP consisting of PNFTBMA and PtTFPP exerted high pressure sensitivity and low temperature sensitivity. In the absence of oxygen, the temperature sensitivity decreased in the order of PTFEMA > PHFIPMA > PNFTBMA = PMMA, which corresponds to the order of glass transition temperatures (T_g). However, the activation energies of the overall process of the luminescence quenching by oxygen were 16.8 (PMMA), 13.0 (PTFEMA), 6.8 (PHFIPMA), and 4.3 kJ mol^-1 (PNFTBMA). Therefore, the low temperature sensitivity of PNFTBMA was attributed to its high degree of substitution with CF₃ groups and to its relatively high T_g value. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Formula: C7H6F6O2).

1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Formula: C7H6F6O2

Orientation Control in Thin Films of a High-蠂 Block Copolymer with a Surface Active Embedded Neutral Layer was written by Zhang, Jieqian;Clark, Michael B.;Wu, Chunyi;Li, Mingqi;Trefonas, Peter;Hustad, Phillip D..

Directed self-assembly (DSA) of block copolymers (BCPs) is an attractive advanced patterning technol. being considered for future integrated circuit manufacturing By controlling interfacial interactions, self-assembled microdomains in thin films of polystyrene-block-poly(Me methacrylate), PS-b-PMMA, can be oriented perpendicular to surfaces to form line/space or hole patterns. However, its relatively weak Flory interaction parameter, 蠂, limits its capability to pattern sub-10 nm features. Many BCPs with higher interaction parameters are capable of forming smaller features, but these “high-蠂” BCPs typically have an imbalance in surface energy between the resp. blocks that make it difficult to achieve the required perpendicular orientation. To address this challenge, we devised a polymeric surface active additive mixed into the BCP solution, referred to as an embedded neutral layer (ENL), which segregates to the top of the BCP film during casting and annealing and balances the surface tensions at the top of the thin film. The additive comprises a second BCP with a “neutral block” designed to provide matched surface tensions with the resp. polymers of the main BCP and a “surface anchoring block” with very low surface energy that drives the material to the air interface during spin-casting and annealing. The surface anchoring block allows the film to be annealed above the glass transition temperature of the two materials without intermixing of the two components. DSA was also demonstrated with this embedded neutral top layer formulation on a chem. patterned template using a single step coat and simple thermal annealing. This ENL technol. holds promise to enable the use of high-蠂 BCPs in advanced patterning applications. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Related Products of 3063-94-3).

Modular Zwitterion-Functionalized Poly(isopropyl methacrylate) Polymers for Hosting Luminescent Lead Halide Perovskite Nanocrystals was written by Cohen, Theodore A.;Huang, Yunping;Bricker, Nico A.;Juhl, Connor S.;Milstein, Tyler J.;MacKenzie, J. Devin;Luscombe, Christine K.;Gamelin, Daniel R.. And the article was included in Chemistry of Materials in 2021.Application of 3063-94-3 The following contents are mentioned in the article:

Inorganic lead halide perovskite nanocrystals (NCs) are an exciting class of luminescent materials with high defect tolerance and broad spectral tunability, but such NCs are vulnerable to degradation under ambient conditions. Here, we report a class of modular zwitterion-functionalized iso-Pr methacrylate polymers designed to stabilize a wide variety of perovskite NCs of different compositions, while also enabling processing in green solvents. Specifically, we report polymers in which the zwitterion spacing is tuned to accommodate the different lattice parameters of CsPb(Cl_1-xBr_x)₃ and CsPbI₃ NCs, and we report partially fluorinated polymers prepared to accommodate the needs of IR-emitting NCs. We show that as-synthesized CsPbBr₃, CsPbI₃, and Yb³⁺:CsPbCl₃ NCs are easily transferred into these zwitterionic polymers via a simple ligand-exchange procedure. These NC/polymer composites were then cast into thin films that showed substantially improved photoluminescence (PL) and stability compared with more conventional NC/polymer films. Specifically, CsPbBr₃ and CsPbI₃ NCs in films of their appropriately designed polymers had PL quantum yields of ~90% and ~80%, resp. PL quantum yields decreased under continuous illumination but self-healed completely after dark storage. We also found that all the NC compositions studied here maintain their PL quantum yields in NC/polymer composite films even after 1 yr of ambient storage. These encouraging results demonstrate the utility of such modular zwitterion-functionalized polymers for hosting specific perovskite NCs, potentially opening avenues for robust new photonic applications of this important class of NCs. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Application of 3063-94-3).

Trifluoroethyl聽methacrylate (I) [38785-10-3] was prepared from trifluoroethanol聽聽[75-89-8] and methacryloyl chloride (II) in 14% yield. Hexafluoroisopropyl聽methacrylate聽聽[3063-94-3](III) was prepared from hexafluoroisopropanol聽聽[920-66-1] and II in the presence of Et₃N in 15% yield. Homopolymerization of I and its copolymerization with Me methacrylate (IV) were performed in the presence of 0.5% 2,2′-azobis-2,4-dimethyl-4-methoxyvaleronitrile at 0掳 in sealed tubes. The homopolymerization of III were carried out in the presence of Bz₂O₂ at 60掳 in C₆H₆. Polymers thus obtained were purified by reprecipitation from C₆H₆, CH₂Cl₂, or Me₂CO/MeOH. Every polymer obtained was soluble in C₆H₆ etc., except III-homopolymer [28825-23-2] which was soluble in Et₂O. Calf serum albumin (VI), egg white lysozyme (VII) [9001-63-2], and pig gastric mucin (VIII) were labeled with ¹²⁵I, dissolved in pH 7.30 phosphate buffer solution, and were adsorbed on the polymer films prepared above. VI adsorption decreased slightly and that of VIII increased significantly with increasing I and III content in the copolymers with IV, whereas VII adsorption was not affected by the film composition This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Name: 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate).

1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Name: 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate

Application of life cycle assessment and machine learning for high-throughput screening of green chemical substitutes was written by Zhu, Xinzhe;Ho, Chi-Hung;Wang, Xiaonan. And the article was included in ACS Sustainable Chemistry & Engineering in 2020.Safety of 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate The following contents are mentioned in the article:

The production process of many active pharmaceutical ingredients such as sitagliptin could cause severe environmental problems because of the use of toxic chem. materials and production infrastructure, energy consumption, and waste treatment. The environmental impacts of the sitagliptin production process were estimated with a life cycle assessment (LCA) method, which suggested that the use of chem. materials provided the major environmental impacts. Both methods of Eco-indicator 99 and ReCiPe endpoint confirmed that chem. feedstock accounted for 83% and 70% of life-cycle impact, resp. Among all the chem. materials used in the sitagliptin production process, trifluoroacetic anhydride was identified as the largest influential factor in most impact categories according to the results of the ReCiPe midpoints’ method. Therefore, high-throughput screening was performed to seek for greener chem. substitutes to replace the target chem. (i.e., trifluoroacetic anhydride) by the following three steps. First, the 30 most similar chems. were obtained from 2 million candidate alternatives in the PubChem database on the basis of their mol. descriptors. Thereafter, deep learning neural network models were developed to predict life-cycle impact according to the chems. in Ecoinvent v3.5 database with known LCA values and corresponding mol. descriptors. Finally, 1,2-ethanediyl ester was proved to be one of the potential greener substitutes after the LCA data of these similar chems. were predicted using the well-trained machine learning models. The case study demonstrated the applicability of the novel framework to screen green chem. substitutes and optimize the pharmaceutical manufacturing process. Neural network models were trained using mol. descriptors and life-cycle impact of known chems. and used to search greener substitutes in a huge library of chems. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Safety of 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate).

Initiation reactivity of anionic polymerization of fluorinated acrylates and methacrylates with diethyl(ethyl cyanoacetato)aluminum was written by Umino, Youhei;Narita, Tadashi;Hamana, Hiroshi. And the article was included in Journal of Polymer Science, Part A: Polymer Chemistry in 2008.Formula: C7H6F6O2 The following contents are mentioned in the article:

Pseudo first-order rate constants of the reaction of diethyl(Et cyanoacetato)aluminum [(C₂H₅)₂Al(NCCHCOOC₂H₅)] with 17 fluorinated acrylates and methacrylates and five hydrocarbon analogs for references were investigated to examine the initiation reactivities of the anionic polymerization of fluorinated vinyl monomers to afford the reactivity order: CH₂=C(CF₃)COOC₂H₅ > CH₂=C(CF₃)COOCH(CH₃)₂ > CH₂=CHCOOCH₂C₆F₅ > CH₂=C(CF₃)COOC(CH₃)₃ > CH₂=C(CF₃)COOCH₂C₆F₅ > CH₂=C(CF₃)COOCH(CF₃)₂ 鈮?CH₂=CHCOOCH₃ > CH₂=CHCOOCH₂C₆H₅ 鈮?CH₂=C(CF₃)COOCH₂CF₃ > CH₂=C(CH₃)COOCH₂C₆F₅ > CH₂=CHCOOCH₂CF₃ > CH₂=CHCOOCH₂C₂F₅ > CH₂=CHCOOCH(CF₃)₂ > CH₂=C(CH₃)COOCH₃ > CH₂=C(CH₃)COOCH₂C₆H₅ 鈮?CH₂=C(CH₃)COOCH₂CH₂ C₈F₁₇ > CH₂=C(CH₃)COOCH(CH₃)₂ > CH₂=C(CH₃)COOCH₂C₂F₅ 鈮?CH₂=C(CH₃)COOCH₂CF₃. No rate constants for CH₂=C(CH₃)COOCH(CF₃)₂, CH₂=CFCOOC(CH₃)₃, and CH₂=CFCOOCH₂C₂F₅ were obtained because of too fast polymerization The incorporation of a trifluoromethyl group into the vinyl group enhanced the reactivity toward the delocalized carbanion. The reactivity of other fluorinated acrylates and methacrylates was concluded to approx. be controlled by the fluorine contents and the bulkiness of substituents of monomers. The reactivity was generally decreased by increasing fluorine contents of fluoroalkyl substituents in ester groups. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Formula: C7H6F6O2).

1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120掳 C鈥揅鈥揙 and O鈥揅鈥揙 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C鈥揙鈥揅 bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
