The multistep synthesis, characterization. and properties of the well defined six carbazolyl and branched aliphatic chain containing organic photosemiconductor is reported. It was prepared by the nucleophilic opening of the oxirane cycle of 1,6-di(carbazol-9-yl)-5-(carbazol-9-methyl)-4-oxa-2-hexanol glycidyl ether with the linking agent 4,4'-thiobisbenzenethiol in the presence of catalyst triethylanaine (TEA). The molecular structure of this branched molecular glass prevents its crystallization in the layer and allows stable films to be prepared without binder material. The hole drift mobility, measured by the time-of-flight technique, reaches 10(-5) cm(2)/V(.)s at an electric field of 10(6)V(.)cm(-1). The value of ionization potential (5.92eV) measured by the electron photoemission method in air is close to those reported for the other organic photoconductors containing electronically isolated carbazolyl moieties.
