Abstract:
1. A material for an organic electroluminescence device of formula (1): wherein X is an oxygen atom or a sulfur atom; R each of a to d and h is independently an integer of from 0 to 4; each of e to g is independently an integer of from 0 to 3; a total of a to h is 6 or less; and L is a single bond, an alkylene group having 1 to 20 carbon atoms, a cycloalkylene group having 3 to 20 ring carbon atoms, an arylene group having 6 to 18 ring carbon atoms, or a heteroarylene group having 5 to 18 ring atoms; L is optionally substituted with an optionally substituted alkyl group having 1 to 20 carbon atoms, an optionally substituted cycloalkyl group having 3 to 20 ring carbon atoms, an optionally substituted alkoxy group having 1 to 20 carbon atoms, an optionally substituted cycloalkoxy group having 3 to 20 ring carbon atoms, an optionally substituted aryl group having 6 to 18 ring carbon atoms, an optionally substituted aryloxy group having 6 to 18 ring carbon atoms, an optionally substituted heteroaryl group having 5 to 18 ring atoms, an optionally substituted amino group, an optionally substituted silyl group, an optionally substituted fluoro group, or an optionally substituted cyano group, and the material is suitable for an organic electroluminescence device.
