ORGANIC ELECTROLUMINESCENT DEVICE MATERIAL, ORGANIC ELECTROLUMINESCENT DEVICE, DISPLAY AND ILLUMINATING DEVICE

摘要

Disclosed is an organic electroluminescent device material which is characterized by containing a platinum complex represented by the general formula (1) wherein an oxygen atom or a sulfur-containing group is introduced at the 4-position of a phenyl pyridine, which is a ligand of the platinum complex, and a specific substituent is further introduced at a specific position thereof. In the general formula (1) shown in the description, R1, R2, R3, R4, R5, R6 and R7 respectively represent a hydrogen atom or a substituent, and at least one of them represents an electron-donating substituent. Also disclosed are an organic EL device, illuminating device and display using such an organic electroluminescent device material.
