Abstract Two tetraphenylethylene-based fluorescent conjugated microporous polymers (TTTPT and TTDAT) were obtained by the Friedel−Crafts polymerization reactions catalyzed by CH3SO3H. In virtue of containing tetraphenylethylene, triphenylamine and s-triazine units in their porous skeletons, the resulting TTTPT and TTDAT show excellent fluorescence sensing performance for trinitrophenol with high quenching coefficients of 9.13×103 and 1.31×105 L mol-1, respectively. TTDAT can also sense to dinitrophenol with the Ksv of 2.70×104 L mol-1. The fluorescent quenching mechanisms of TTTPT and TTDAT for selective detecting TNP attribute to conventional photoinduced electron-transfer mechanism and/or the resonant energy transfer mechanism.
