We synthesized six conjugated compounds based on para-& meta- tolyl carbazole derivatives, 9,9'-Di-p-tolyl-9H,9'H-[3,3']bicarbazolyl(p-TBC), 9,9',9''-Tri-p-tolyl-9H,9'H, 9''H-[3,3';6',3'']tercarbazole(p-TTC),9,9'-Di-p-tolyl-6,6'-bicarbazolyl-9H,9'H-[3,3']bicarbazolyl(p-TBCBC), 9,9'-Di-m-tolyl-9H,9'H-[3,3']bicarbazolyl(m-TBC), 9,9',9''-Tri-m-tolyl-9H,9'H,9''H-[3,3';6',3'']tercarbazole(m-TTC) and 9,9'-Di-m-tolyl-6,6'-bicarbazolyl–9H,9'H-[3,3']bicarbazolyl(m-TBCBC) by Suzuki and C-N coupling reactions. The obtained compounds were identified by 1H-NMR, IR and FAB-Mass spectroscopy. Electro-optical properties were characterized by cyclic voltammetry and photoluminescence spectra. Electroluminescent properties were also investigated in these organic materials. |
