Abstract:
It is intended to provide a novel material having no absorption or low absorption intensity in the visible region and to provide an electroluminescent device excellent in hole injection characteristic by using the novel material. A novel organic material wherein two electron abundant aromatic rings inherently having a low ionization potential, such as a thiophene ring, a furan ring, and pyrrol ring, is intervened by a conjugated substituent such as a phenylene ring is provided. The electroluminescent device having an excellent hole injection characteristic is provided by using this novel organic material.
