Abstract
An object of the invention is to provide a charge transporting material having an excellent heat resistance, excellent filming properties, an excellent charge transporting ability, and excellent light-emitting characteristics and, also, to provide an organic electroluminescent element providing a high luminance and a highly luminous efficiency and having a long life.The invention relates to a charge transporting material comprising a compound having within the molecule two or more pyridine rings substituted at 2-, 4- and 6-positions thereof, which rings do not substantially conjugate each other (provided that the 3- and 5-positions of the pyridine rings may be substituted) and an organic electroluminescent element using the charge transporting material.
