A fluorescent group containing novel asymmetric star shaped derivatives of 2,4,6-trichloro-1,3,5-triazine containing 2-hydroxy carbazole and (1,8-dihydropyren-1-yl)methanamine were designed, synthesized and characterized. Electrochemical polymerization of TPC was performed in acetonitrile (ACN)/LiClO4. Electrochromic properties of the conducting polymers were investigated via spectroelectrochemistry, kinetic and colorimetry studies. Spectroelectrochemical analysis of PTPC revealed electronic transitions at 308, 460 and 780 nm corresponding to π-π* transition, polaron, and bipolaron band formations, respectively. Moreover, PTPC illustrate electrochromic behavior: greenish in the oxidized state and transparent in the neutral state. Furthermore, fluorescence properties of this new type monomer were investigated.
