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 fluorescence-emission at 482 nm in fluorescence 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 e V, respectively.
