  • Publication number: 20090179553
    Abstract: The invention relates to electroluminescent materials containing organic luminescent substance. The inventive novel electroluminescent material comprises an electron injecting layer, an active luminescent layer based on a luminescent substance, a hole-transport layer and a hole-injecting layer. The material contains metallocomplexes of quinoline-sulfanylamine derivatives in the form of a luminescent substance. The inventive electroluminescent material exhibits the increased time resource, resulting from the high resistance of the active luminescent layer to crystallisation and hydrolysis, and the high heat resistance of the hole-transport layer.
