COMPOUND, CHARGE TRANSPORT MATERIAL AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

A charge transport material exhibiting excellent thermal stability, film forming capability, charge transport capability and luminescence characteristics; and an organic electroluminescent device of high luminance, high light emitting capability and prolonged operating life. There is provided a charge transport material comprising a compound containing two or more pyridine rings substituted at 2,4,6-positions in its molecule characterized in that the pyridine rings are substantially not conjugated with each other (provided that the pyridine rings may be optionally substituted at the 3,5-positions thereof), and further provided an organic electroluminescent device including the charge transport material.
