Abstract

A series of fluorescently labeled core cross-linked star (CCS) polymers were synthesized via the "arm-first" approach, employing atom transfer radical polymerization (ATRP) to control the resulting architecture. The initiator p-toluenesulfonyl chloride (TsCl) was used to synthesize "living" poly(methyl methacrylate) (PMMA) macroinitiator, which was subsequently cross-linked to generate the CCS polymers. Divinylbenzene (DVB) was used as the cross-linker and 7-[4-(trifluoromethyl)coumarin] methacrylamide (F1, λex = 343 nm) was added as a fluorescent labeling monomer. A range of PMMA/DVB/F1 based CCS polymers were synthesized with the core domain made selectively fluorescent by using varying am..
