Doi, Toru published the artcileElucidation of mechanism for living radical polymerization of styrene with N,N-diethyldithiocarbamate derivatives as iniferters by the use of spin trapping technique, Name: Benzyl diethylcarbamodithioate, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (1994), 32(12), 2241-9, database is CAplus.

The photodissociation of several N,N-diethyldithiocarbamate derivatives (RDC), i.e., benzyl, 1-phenylethyl, 2-phenylethyl, Bu, sec-, and tert-Bu N,N-diethyldithiocarbamates, was investigated by the spin trapping technique to elucidate the polymerization mechanism of styrene (I) with RDC as iniferters. The scission of RDC occurred at two different C-S bonds depending on the structure of the alkyl groups of RDC and the cleavage manner was dominated by both resonance and steric effects. RDC generating an N,N-diethyldithiocarbamyl radical acts as an effective iniferter and induces the living radical polymerization of I in homogeneous system. The polymerizations of I with tetraethylthiuram disulfide and p-xylylene bis(N,N-diethyldithiocarbamate) were also discussed on the basis of the results of the spin trapping for RDC as the model compounds of the polystyrene chain ends.

Doi, Toru published the artcileRadical polymerization of methyl acrylate by use of benzyl N,N-diethyldithiocrbamate in combination with tetraethylthiuram disulfide as a two-component iniferter, Formula: C12H17NS2, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (1994), 32(15), 2911-18, database is CAplus.

Polymerization of Me acrylate with benzyl N,N-diethyldithiocarbamate (BDC) was carried out in bulk or in benzene under UV irradiation The polymerization proceeded to give high yield of polymer, however it was found that BDC did not function as an iniferter in the MA polymerization Bimol. termination leading to deactivation of the iniferter site was observed during the polymerization in preference to chain transfer and primary radical termination which reproduce the iniferter site. The deactivation was successfully prevented by combining BDC and tetraethylthiuram disulfide as a two-component iniferter. This two-component iniferter system was also applied to synthesis of a star polymer with 1,2,4,5-tetrakis(N,N-diethyldithiocarbamylmethyl)benzene as a tetrafunctional photoiniferter.

Marchyk, Nataliya published the artcileOne-pot synthesis of iniferter-bound polystyrene core nanoparticles for the controlled grafting of multilayer shells, HPLC of Formula: 3052-61-7, the publication is Nanoscale (2014), 6(5), 2872-2878, database is CAplus and MEDLINE.

A novel approach using one-pot synthesis for the production of uniform, iniferter-bound polystyrene core nanoparticles of size 30-40 nm is described. Conventional oil-in-water emulsion polymerization of styrene and divinylbenzene, combining a hybrid initiation system (thermal and UV), triggered sequentially, was employed to form the surface-bound thiocarbamate iniferters in situ. The iniferter cores were then used as seeds for re-initiating further polymerization by UV irradiation to produce water-compatible core-shell nanoparticles. Grafting of various shell-types is demonstrated: linear polymers of poly(N-isopropylacrylamide) brushes, crosslinked polymers bearing different surface charges and molecularly imprinted polymers. The shell thickness was readily tuned by varying the monomers’ concentration and polymerization time. Our method is straightforward and in addition, gives access to the preparation of fluorescent seeds and the possibility of grafting nanosized multiple shells. The core-shell nanoparticles were fully characterized by dynamic light scattering, transmission electron microscopy, Fourier transform IR spectroscopy and microelemental anal.

Chiefari, John published the artcileThiocarbonylthio Compounds (S:C(Z)S-R) in Free Radical Polymerization with Reversible Addition-Fragmentation Chain Transfer (RAFT Polymerization). Effect of the Activating Group Z, SDS of cas: 3052-61-7, the publication is Macromolecules (2003), 36(7), 2273-2283, database is CAplus.

Free-radical polymerization in the presence of suitable addition-fragmentation chain transfer agents [S:C(Z)S-R] (RAFT agents) possess the characteristics of a living polymerization (i.e., polymer products can be reactivated for chain extension and/or block synthesis, mol. weights are predetermined by RAFT agent concentration and conversion, narrow polydispersities are possible). Styrene polymerizations (110 °C, thermal initiation) were performed for two series of RAFT agents [S:C(Z)S-CH₂Ph and S:C(Z)S-C(Me)₂CN]. The chain transfer coefficients decrease in the series where Z is Ph > SCH₂Ph ∼ SMe ∼ Me ∼ N-pyrrolo ≫ OC₆F₅ > N-lactam > OC₆H₅ > O(alkyl) ≫ N(alkyl)₂ (only the first five in this series provide narrow polydispersity polystyrene (< 1.2) in batch polymerization). More generally, chain transfer coefficients decrease in the series dithiobenzoates > trithiocarbonates ∼ dithioalkanoates > dithiocarbonates (xanthates) > dithiocarbamates. However, electron-withdrawing substituents on Z can enhance the activity of RAFT agents to modify the above order. Thus, substituents that render the oxygen or nitrogen lone pair less available for delocalization with the C:S can substantially enhance the effectiveness of xanthates or dithiocarbamates, resp. The trend in relative effectiveness of the RAFT agents is rationalized in terms of interaction of Z with the C:S double bond to activate or deactivate that group toward free radical addition MO calculations and the estimated LUMO energies of the RAFT agents can be used in a qual. manner to predict the effect of the Z substituent on the activity of RAFT agents.

Martens, Frank K. published the artcileSignificance of the rubidium bromide thermionic detector equipped with a gate electrode in the analysis of halogenated dithiocarbamate derivatives, Application of Benzyl diethylcarbamodithioate, the publication is Journal of Chromatography (1977), 140(1), 86-92, database is CAplus.

A gas chromatog. detection method by using a RbBr thermionic detector equipped with a gate electrode is established to improve the identification of halogenated and nonhalogenated dithiocarbamate benzyl esters. An inversion of the thermionic system signal was observed on changing the polarities around the jet and the collector. Each compound, depending on its heteroatom, inverts at a different gate potential. Very accurate control of the voltage supply to the gate electrode around the flame tip provides the possibility of collecting fixed inversion potentials, characteristic for compounds with a certain heteroatom constitution. The peak inversion phenomenon makes a valuable contribution to a specific identification of derivatized dithiocarbamates.

Dong, Jiande published the artcileSynthesis and biological imaging of cross-linked fluorescent polymeric nanoparticles with aggregation-induced emission characteristics based on the combination of RAFT polymerization and the Biginelli reaction, Name: Benzyl diethylcarbamodithioate, the publication is Journal of Colloid and Interface Science (2018), 192-199, database is CAplus and MEDLINE.

Fluorescent probes have long been regarded as tools for imaging living organisms with advantages such as high sensitivity, good designability and multifunctional potential. Many fluorescent probes, especially the probes based on aggregation-induced emission (AIE) dyes, have received increasing attention since the AIE phenomenon was discovered. These AIE dye-based fluorescent probes could elegantly overcome the notorious quenching effect caused by aggregation of conventional organic dyes. However, it is still difficult to directly apply these AIE-active dyes for biomedical applications owing to their hydrophobic nature. Therefore, the development of novel and facile strategies to endow them with water dispersibility is of critical importance. In this work, we exploit an efficient and simple strategy to fabricate an AIE dye-based fluorescent copolymer through the combination of reversible addition-fragmentation chain transfer and the Biginelli reaction. Moreover, the copolymer can self-assemble to fluorescent polymeric nanoparticles (FPNs) in water solution Hydrophilic poly(PEGMA-co-AEMA) was reacted with the AIE-active dye 4′,4”’-(1,2-diphenylethene-1,2-diyl)bis([1,1′-biphenyl]-4-carbaldehyde) (CHO-TPE-CHO) to form amphiphilic luminescent polymers using urea as the connection bridge. The successful synthesis of the final products (poly(PEGMA-co-AEMA-TPE) FPNs) was confirmed by various instruments. Furthermore, Transmission electron microscopy (TEM) images manifest that poly(PEGMA-co-AEMA-TPE) copolymers will self-assemble into spherical nanoparticles in aqueous environments with sizes between 100 nm and 200 nm. The cell uptake and bioimaging experiment confirm that poly(PEGMA-co-AEMA-TPE) FPNs have excellent biocompatibility and emit strong green fluorescence in a cellular environment. Thus, poly(PEGMA-co-AEMA-TPE) FPNs are excellent candidates for biomedical applications.

Dong, Jiande published the artcileUltrafast fabrication of fluorescent organic nanoparticles with aggregation-induced emission feature through the microwave-assisted Biginelli reaction, COA of Formula: C12H17NS2, the publication is Dyes and Pigments (2019), 90-96, database is CAplus.

Because of its unique optical properties, the aggregation-induced emission (AIE) dye has attracted extensive attention for various applications. Especially, the utilization of AIE-active dyes for fabrication of fluorescent organic nanoparticles (FONs) has attracted the most research interest for biomedical applications. Therefore, the development of novel and effective strategies to design and prepare AIE-active FONs should be of great importance for the biomedical applications of AIE-active FONs. In this report, we reported an ultrafast strategy that based on the one-pot microwave-assisted Biginelli reaction for fabrication of AIE-active poly(AA-AEMA-TPE) copolymers, which use the 2-(methacryloyoxy)ethylacete, acrylic acid (AA) and 4′,4”’-(1,2-diphenylethene-1,2-diyl) bis([1,1′-biphenyl]-4-carbaldehyde) (TPE-CHO) as the substrates. The microwave-assisted Biginelli reaction is simple, efficient and atom-economical and can be accomplished within 3 min. Owing to their amphiphilicity, poly(AA-AEMA-TPE) copolymers will self-assemble into FONs with small size and high water dispersibility. The proton NMR (¹H NMR) spectroscopy, UV-Vis spectrum and fluorescence spectrometer were used to characterize the resultant copolymers. We demonstrated that poly(AA-AEMA-TPE) FONs possess many excellent properties, such as high water dispersibility, intense fluorescence, obvious AIE feature and favorable biocompatibility. The above results suggest that poly(AA-AEMA-TPE) FONs are of great potential for fluorescent imaging. Moreover, the microwave-assisted Biginelli reaction can occur under a rather benign environment with high efficiency and good substrate adaptability. Therefore, we believe that the method developed in this work could greatly advance the applications of AIE-active functional materials.
