•A series of dibenzotetracene derivatives were synthesized.•Single crystal analysis shows these compounds have twisted structures.•Electroluminescent devices were fabricated to assess the performance of the new dibenzotetracene.
A series of dibenzotetracene derivatives containing different substituents at the 11-,12-positions have been successfully synthesized and characterized. Single crystal X-ray analysis indicates that the new molecules have a twisted structure, which can effectively decrease the intermolecular aggregation in the solid-state. The effect of both substituent and packing on the corresponding physical properties was also investigated. In addition, organic light-emitting diodes doped with 11,12-difluoro-9,14-diphenyl-dibenzo[de,qr]tetracene into the emitter 9,9′-(1,3-phenylene)bis-9H-carbazole were fabricated and exhibit good performance.
