pH-responsive alkynylplatinum(II) 2,6-bis(benzimidazol-2閳?yl)pyridine (bzimpy) complexes with charge-reversal properties were synthesized, and the supramol. assemblies between conjugated polyelectrolyte, PFP-OSO₃^–, and [Pt{bzimpy(TEG)₂}{C椤氬挵-C₆H₃-(COOH)₂-3,5}]Cl (1) were studied using UV-visible absorption, emission, and resonance light scattering (RLS) spectroscopy. An efficient Forster resonance energy transfer (FRET) from PFP-OSO₃^– donor to the aggregated 1 as acceptor with the aid of Pt(II)璺矾璺疨t(II) interactions was presented, which leads to a growth of triplet metal-metal-to-ligand charge transfer (³MMLCT) emission in the low-energy red region. The two-component PFP-OSO₃^––1 ensemble was then exploited as a proof-of-principle concept strategy for pH sensing by tracking the ratiometric emission changes. With the aid of judicious mol. design on the pH-driven charge-reversal property, the polyelectrolyte-induced self-assembly and the FRET from PFP-OSO₃^– to the Pt(II) aggregates were modulated. Together with its excellent reversibility and photostability, the extra stability provided by the Pt(II)璺矾璺疨t(II) and 锜?锜?stacking interactions on top of the electrostatic and hydrophobic interactions existing in polyelectrolye-complex assemblies led to a selective and sensitive pH sensing assay. In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5Related Products of 313648-56-5).

Dimethyl 5-ethynylisophthalate (cas: 313648-56-5) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Related Products of 313648-56-5

High methane storage and working capacities in a NbO-type metal-organic framework was written by Song, Chengling;Liu, Huimin;Jiao, Jingjing;Bai, Dongjie;Zhou, Wei;Yildirim, Taner;He, Yabing. And the article was included in Dalton Transactions in 2016.Category: esters-buliding-blocks This article mentions the following:

To improve methane adsorption by pore structure optimization, we developed a new organic linker and used it to construct a NbO-type metal-organic framework ZJNU-53 that, after activation, exhibits exceptionally high methane storage and working capacities of 241 and 190 cm³ (STP) cm^-3 at 298 K and 65 bar, resp., if the packing loss is not considered, which are among the highest reported for MOF materials. In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5Category: esters-buliding-blocks).

Dimethyl 5-ethynylisophthalate (cas: 313648-56-5) 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. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Category: esters-buliding-blocks

Water-soluble anionic fluorophores from truxene was written by Earmrattana, Nopporn;Sukwattanasinitt, Mongkol;Rashatasakhon, Paitoon. And the article was included in Dyes and Pigments in 2012.Recommanded Product: 313648-56-5 This article mentions the following:

Two new water-soluble fluorophores are synthesized from truxene and ester-substituted aryl acetylenes. The truxene core is decorated by 2-(2′-methoxy)ethoxyethyl groups to enhance the hydrophilicity of these fluorophores and to prevent the aggregation by π-stacking in aqueous media. The conjugated structures are assembled by iodination of the truxene core and subsequent Sonogashira coupling with aryl acetylenes. Upon the hydrolysis of the ester groups, water-soluble fluorophores are obtained in good to excellent yield (30-71% for 3 steps). A photophys. study reveals that these compounds exhibit strong fluorescence signals (quantum yield 46-63%) with maximum emission wavelength around 390-400 nm in aqueous phosphate buffer. Preliminary screening on sensing application shows that their fluorescent signals can be selectively quenched by porphyrin-containing metalloproteins. In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5Recommanded Product: 313648-56-5).

Dimethyl 5-ethynylisophthalate (cas: 313648-56-5) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 313648-56-5

A chiral interlocking auxiliary strategy for the synthesis of mechanically planar chiral rotaxanes was written by de Juan, Alberto;Lozano, David;Heard, Andrew W.;Jinks, Michael A.;Suarez, Jorge Meijide;Tizzard, Graham J.;Goldup, Stephen M.. And the article was included in Nature Chemistry in 2022.Name: Dimethyl 5-ethynylisophthalate This article mentions the following:

A combination of reaction partners that function as a chiral interlocking auxiliary to both orientate a macrocycle and effectively, load it onto a new axle was discovered. These substrates was used to demonstrate the potential of a chiral interlocking auxiliary strategy for the synthesis of mech. planar chiral rotaxanes by producing a range of examples with high enantiopurity (93-99% e.e.), including so-called ‘impossible’ rotaxanes whose axles lack any functional groups that would allow their direct synthesis by other means. Intriguingly, by varying the order of bond-forming steps, can effectively choose which end of an axle the macrocycle is loaded onto, enabling the synthesis of both hands of a single target using the same reactions and building blocks. In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5Name: Dimethyl 5-ethynylisophthalate).

Dimethyl 5-ethynylisophthalate (cas: 313648-56-5) 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. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C 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.
