Synthesis and characterization of poly (N-Hexyl-2, 7-di(2-(4-hexylthiophene)carbazole)
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, 1 H-NMR, 13 C-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 ( E g ), HOMO energy ( E HOMO ), and LUMO energy ( E LUMO ) of the polymer were obtained as 2.58, -5.32, and -2.74 eV, respectively.
