Smart block copolymers as fluorescence chemosensors of copper ions with high detection limit

Stimuli-responsive block copolymers were synthesized to detect copper ions with high limit based on a fluorescence quenching mechanism. For this purpose, poly(7-acryloyloxy 4-methylcoumarin-r-methyl methacrylate)-b-poly(dimethylaminoethyl methacrylate) in three different block ratios was synthesized by reversible addition-fragmentation chain-transfer (RAFT) polymerization. Successful synthesis of the block copolymers was confirmed by...
