Dibenzocarbazolediimides: synthesis, solid structure, self-assembly behavior, and optoelectronic properties

Both planar and nonplanar polycyclic aromatic hydrocarbons (PAHs) have attracted attention owing to their potential applications in optoelectronic materials. Four twist benzopicenediimides with good optoelectronic properties have been reported previously. Following on from this work, four functionalized dibenzocarbazoles have been synthesized and reported herein. The fluorescence quantum yields of these compounds were high in dichloromethane and moderate in the solid state. They have interesting self-assembling behavior and tunable packing motifs in single crystals obtained by introducing different functional groups. Their good optoelectronic properties make them potential candidates for organic devices, bioimaging, and biolabeling.
