ORGANIC EL MATERIAL-CONTAINING SOLUTION, METHOD FOR SYNTHESIZING ORGANIC EL MATERIAL, COMPOUND SYNTHESIZED BY THE SYNTHESIZING METHOD, METHOD FOR FORMING THIN FILM OF ORGANIC EL MATERIAL, THIN FILM OF ORGANIC EL MATERIAL, AND ORGANIC EL 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.
