ELECTROLUMINESCENT MATERIAL CONTAINING AN ORGANIC LUMINESCENT SUBSTANCE

摘要

The invention relates to electroluminescent material containing an organic luminescent substance. The novel electroluminescent material consists of an electron injecting layer, an active luminescent layer based on a metal chelate complex, a hole transport layer and a hole injecting layer. The electroluminescent material contains zinc complexes based on sulfonylamine derivatives of 2-phenyl-benzoxasole or 2-phenyl-benzothiasole as a luminescent substance. The material preferably contains a mixture of triphenylamine oligomers as a hole transport layer. Said invention makes it possible to develop an electroluminescent material, the emission colour of which is close to white and which exhibits a high luminous efficiency and a high heat stability.
