There is provided an organic compound of excellent characteristics that exhibits excellent hole-injecting/transporting performance and has an electron blocking ability and a highly stable thin-film state with excellent heat resistance. The compound of the present invention is an arylamine compound having a triphenylamine structure. The arylamine compound is used as a constituent material of at least one organic layer in an organic electroluminescent device that includes a pair of electrodes, and one or more organic layers sandwiched between the pair of electrodes.
to amorphous organicmaterials. Because the functionalgroup orientation has not been discussed in detail, the relationship between the electrical properties of the films and the molecular orientation of amorphous organicmaterials remains unclear. In this study, to solve the ambiguity of molecular orientation, we investigate the functionalgroup orientation of a hole transport material for OLEDs in
