Title:

COMPOUND HAVING SPIRO BOND, MATERIAL FOR LUMINESCENT COATING FORMATION AND ORGANIC ELECTROLUMINESCENCE ELEMENT INCLUDING THE SAME

Document Type and Number:

WIPO Patent Application WO/2004/110968

Kind Code:

A1

Abstract:

A novel compound having spiro bond with specified structure; and a material for luminescent coating formation, comprising an organic solvent solution containing the compound having spiro bond. There is further provided an organic electroluminescence element comprising a pair of electrodes consisting of a positive electrode and a negative electrode and, interposed therebetween, at least one organic thin-film layer including at least a light emitting layer, wherein at least one of the above at least one organic thin-film layer contains the above compound having spiro bond. The organic electroluminescence element excels in heat resistance, and the thin films as constituents of the element are highly stable. The organic electroluminescence element emits uniform blue light and, irrespective of low voltage, exhibits high luminance and high luminous efficiency. There are provided the compound having spiro bond and material for luminescent coating formation for realizing the organic electroluminescence element.
