Functional Polymers: Copolymer of Fluorene and Triphenylamine Moieties as Chemosensor
Rong Yang, Weibing Wu, Wenyu Wang, Zhen Li,* and Jingui Qin
Conjugated polymer-based fluorescent (CPF) sensors, which generally contain binding positions such as nitrogen, oxygen, and sulfur atoms to interact with different analytes to give detectable optical signals, have attracted much attention in recent years. Zhen Li and co-workers have successfully prepared a new imidazole-functionalized copolymer of fluorene and triphenylamine bearing imidazole groups in the side chain comparing the direct and postfunctional synthetic route, where the direct copolymeriztion strategy proved to be more successful. The chemosensing behavior of the obtained copolymer was carefully studied. The utilization of the metal ion chemosensors to probe anions by an indirect strategy presents a novel way of developing new chemosensors with a detection limit of cyanide down to 1.8 × 10-5 mol⋅L-1 (0.47 ppm).
