ORGANIC-ELECTROLUMINESCENCE-MATERIAL-CONTAINING SOLUTION, METHOD FOR SYNTHESIZING ORGANIC ELECTROLUMINESCENCE MATERIAL, COMPOUND SYNTHESIZED BY THE METHOD, THIN FILM OF ORGANIC ELECTROLUMINESCENCE MATERIAL AND ORGANIC ELECTROLUMINESCENCE DEVICE

摘要

An organic electroluminescent material-containing solution contains an organic electroluminescent material and a solvent. The organic electroluminescent material contains a host and a dopant. The host includes: an organic electroluminescence-functional portion formed of a low-molecular organic electroluminescent material; and a soluble portion bonded to the organic electroluminescence-functional portion so as to solubilize the low-molecular organic electroluminescent material in the solvent. The soluble portion is a molecular chain formed by polymerizing basic units and the host is an oligomer.
