Synthesis and Fluorescence Properties of Carbazole Based Asymmetric Functionalized Star Shaped Polymer

Abstract

A fluorescent group containing novel asymmetric functionalized star shaped derivative (TPC) of 2,4,6-trichloro-1,3,5-triazine containing 2-hydroxy carbazole and 1-pyrenemethylamine was designed, synthesized and characterized. Polymerization of TPC was achieved in acetonitrile/lithium perchlorate (ACN/LiClO4) solvent/electrolyte couple via electrochemical techniques. Electrochromic properties of the PTPC were investigated via spectroelectrochemistry, kinetic and colorimetry studies. Optoelectrochemical investigation of PTPC displayed electronic transitions at 308, 460 and 780 nm which are correspond to π-π* transition, polaron, and bipolaron band formations, respectively. Moreover, electrochromic and fluorescence properties of PTPC were investigated. For the first time, this study reports the huge potential of asymmetric functionalized triazine compounds as electrochromic material.
