Two tetraphenylethylene-based fluorescent conjugated microporous polymers (TTTPT and TTDAT) were obtained by the Friedel-Crafts polymerization reactions catalysed by CH$_3$SO$_3$H. 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 (TNP) with high quenching coefficients of 1.66 ${\times}$ 10$^4$ and 1.31 ${\times}$ 10$^5$ l mol$^{–1}$, respectively. TTDAT can also sense to dinitrophenol (DNP) with the Ksv of 2.70 ${\times}$ 10$^4$ l mol$^{–1}$. The fluorescent quenching mechanisms of TTTPT and TTDAT for selective detecting TNP attribute to conventional photoinduced electron-transfer mechanism, absorption competition quenching mechanism and/or the resonant energy transfer mechanism.
