Silacyclopentadiene derivatives and an organic electroluminescent element obtained by using the silacyclopentadiene derivative

摘要

An electroluminescence element is characterised in that a silacyclopentadiene derivative expressed by the formula XVI (wherein, X and Y denote independently each other saturated or unsaturated hydrocarbon radicals with from 1 to 6 carbon atoms, alkoxy radicals, alkenyloxy radicals, alkynyloxy radicals, substituted or unsubstituted aryl radicals, or substituted or unsubstituted heterocycles, and from R₁ to R₄ denote independently each other hydrogen, halogens, substituted or unsubstituted alkyl radicals with from 1 to 6 carbon atoms, alkoxy radicals, perfluoroalkyl radicals, perfluoroalkoxy radicals, amino radical, alkylcarbonyl radicals, alkoxycarbonyl radicals, formyl radical, nitroso radical, azo radical, alkylcarbonyloxy radicals, alkoxycarbonyloxy radicals, formyloxy radicals, supinely radical, sulfonyl radical, sulfanil radical, silyl radical, isocyano radical, carbamoyl radical, cyanate radical, isocyanate radical, thiocyanate radical, isothiocyanate radical, aryl radicals, alkenyl radicals, alkynyl radicals or cyano radical or substituted or unsubstituted condensed rings in the case of being adjacent) is used as a component of a hole-obstructing layer.
