A fluorescent diphenylfluorene-pyrenyl copolymer with dibenzothiophene-S,S-dioxide (SO) and adamantane units has been successfully synthesized via a Suzuki-Miyaura cross-coupling reaction. After studying the sensing properties of a series of diphenylfluorene-pyrenyl materials towards TNT vapor, it was found that the dibenzothiophene-S,S-dioxide (SO) units introduced into the diphenylfluorenepyrenyl copolymers can simultaneously enhance the photostability and sensing performance of the fluorescent sensing materials. This simple strategy can be used as a promising approach for the development of fluorescent conjugated sensing materials.
