Odd–even effect on room-temperature phosphorescence for benzene-carboxylic derivatives

Abstract

In this work, a series of benzene-carboxylic derivative (BCD)-acrylamide copolymers were prepared. All the obtained copolymers exhibited blue afterglow with durations reaching up to 4.64 s. Besides, an interesting odd–even effect was observed between the number of ester groups and the phosphorescent properties.
