The present disclosure provides an organic light-emitting device comprising a novel compound. When the novel compound is applied as a hole transport material to an organic light emitting device, the novel compound allows the device to have improved drive voltage, efficiency and lifespan characteristics.
Effect of Aromatic−Aromatic Interactions on the Conformational Stabilities of Macrocycle and Preorganized Structure during Macrocyclization
4-benzenedicarboxylic acid with the diamine 4 was low (19% yield). Although macrocycle 5 exists in a planar conformation in the crystal and in solution, macrocycle 6 exists in a twisted conformation. A deformation of the twist was induced by a tilted T-shaped aromatic−aromatic interaction between the central phenylene rings of the macrocycle.
