Polgar, Alexander M.;Huang, Shine H.;Hudson, Zachary M. research published 《 Donor modification of thermally activated delayed fluorescence photosensitizers for organocatalyzed atom transfer radical polymerization》, the research content is summarized as follows. Thermally activated delayed fluorescence (TADF) photosensitizers based on 9,10-dihydro-9,9-dimethylacridine/2,4,6-triphenylpyrimidine conjugates with strong visible absorption, large excited state reduction potentials, and long-lived triplet excited states were successfully employed in the organocatalyzed atom transfer radical polymerization (O-ATRP) of methacrylic monomers. A donor-modification strategy dramatically improved the stability of the photocatalyst radical cations, while retaining their high oxidizing strengths, a key requirement for controlled O-ATRP. Time-resolved photoluminescence studies of the catalysts support initiation by electron transfer from both singlet and triplet states, with functionalized donors producing higher driving forces for photoinduced electron transfer. A donor-modified TADF photocatalyst was found for the synthesis of methacrylic polymers with D below 1.3 at catalyst loadings down to 50 ppm. This catalyst was also successfully applied in block copolymer synthesis, while the unfunctionalized analog yields entirely uncontrolled polymerization
Reference of 2495-37-6, Benzyl methacrylate, also known as Benzyl methacrylate, is a useful research compound. Its molecular formula is C11H12O2 and its molecular weight is 176.21 g/mol. The purity is usually 95%.
Benzyl methacrylate is a chemical compound that belongs to the group of benzyl compounds. It has a copolymer structure with methyl ethyl methacrylate (MEMA) and hydroxyl groups. Benzyl methacrylate is produced by polymerization of benzyl chloride with allyl carbonate in the presence of radiation, forming a polymeric matrix. The morphology of this copolymer depends on the length of the benzyl chains and the concentration of MEMA., 2495-37-6.
