Synthesis and Characterization of Poly (N-Hexyl-2, 7-di(2-(4-hexylthiophene)carbazole)

Keywords： polycarbazole

One conjugated polymer consisting of carbazole and 3-hexylthiophene moiety, poly (N-Hexyl-2,7-di(2-(4-hexylthiophene)carbazole) (PNDC), has been synthesized by ferric chloride oxidative polymerization. The monomer N-Hexyl-2,7-di(2-(4-hexylthiophene)carbazole was synthesized and characterized by IR,1H-NMR,13C-NMR and MS. UV-vis absorption spectrum, fluorescence spectrum, photoluminescence spectrum and electrochemical properties of the polymer were investigated. Polymer PNDC shows maximum peak appearing at 394 nm in UV-vis absorption spectrum, strongest lfuorescence-emission at 482 nm in lfuorescence spectrum and maximum emission peak at 492 nm in photoluminescence spectrum. The band-gap (Eg), HOMO energy (EHOMO), and LUMO energy (ELUMO) of the polymer were obtained as 2.58, -5.32, and -2.74 eV, respectively.
