The development of porous polymer films with high emission efficiency simultaneously overcomes the unprocessable and poor photofunctionality limitations faced in the conjugated porous polymers (CPPs) field, and therefore has attracted more and more attentions. In this work, monomer 1,1,2,2-tetrakis(4-(9H-carbazol-9-yl) phenyl)ethene that contained AIE-active tetraphenylethylene and carbazole units had been synthesized via McMurry reaction. And its corresponding CPP (PTCPE) films were easily obtained using the electropolymerization method in CH2Cl2-BFEE mixtures without adding any supporting electrolyte. These CPPs films exhibited high fluorescence in the solid state because of AIE-active TPE. Their electrochemical polymerization and fluorescence properties could be changed by adjusting the polymerization conditions.
