Chain-extended polymers were labeled with an amine-reactive pyrene. (A) RI and UV traces of pDMAEMA-AM-P following pyrene conjugation. (B) Unmodified pDMAEMA-AM shows limited UV absorbance due to the trithiocarbonate moiety on the chain end, while pyrene-labeled pDMAEMA-AM-P exhibits significantly increased absorption.
