Electroluminescence and electron–hole mobility of 6,12-di(thien-2-il)indolo[3,2-b]carbazoles

Resumo

Novel compounds—substituted indolo[3,2-b]carbazoles (SIC)—which demonstrate semiconducting properties are synthesized. Electroluminescence (EL) is studied in multilayer diode structures based on SIC. The values of hole (6.38 × 10^–5 cm²/(V s)) and electron mobilities (1.31 × 10^–5 cm²/(V s)) of these electroactive materials are measured. It is estimated that heteroaromatic nuclei are the electron transport centers of SIC molecules.
