Zwitterionic Monomers Suitable for Biocompatible Polymer Synthesis
M2005 is a zwitterionic-structured methacrylate ester similar to phospholipids. M2359 and A3279 are respectively a methacrylate ester and an acrylamide having a betain-type zwitterionic structure. It's been reported that these monomers are polymerized to give unique biomaterials.
RAFT Agents Effective in Controlled Radical Polymerization
RAFT agents, or chain transfer agents (CTA), are essential mediators for reversible addition-fragmentation chain transfer (RAFT) polymerization reactions, a type of controlled radical polymerization. To achieve these transformations, compounds bearing thiocarbonylthio groups, such as D5561, C3546, and C3534 have been shown to be ideal. They are able to easily release radicals which mediate the reversible chain transfer reactions by virtue of the thiocarbonylthio group.
Coumarins are aromatic lactone compounds and many of them exist in natural plants. A coumarin compound with an electron-donating group on the 7-position shows strong light absorption and luminescence, whereas unsubstituted coumarin compounds are hardly luminescent. This is because intramolecular charge transfer occurs when electron-donating and -withdrawing groups coexist in the coumarin molecule. Coumarin dyes such as coumarin 481 [D4466], coumarin 30 [C2837] and coumarin 521T [C3046] are useful for laser dyes emitting blue-green light.
