Abstract:
1. A material for organic electroluminescence device represented by formula (I); wherein each of A each of X each of R L n represents an integer of 0 to 3, provided that when n=0, L one of X each of sa and ta independently represents an integer of 0 to 5, each of sb, tb and tc independently represents an integer of 0 to 4, and sc represents an integer of 0 to 3, provided that sa+sb+sc+ta+tb+tc represents an integer of 1 to 5; when sa is 1 to 5, A when sb is 1 to 4, at least one of X when sc is 1 to 3, at least one of X when ta is 1 to 5, A when tb is 1 to 4, at least one of Y when tc is 1 to 4, at least one of Y each of Q q represents an integer of 1 to 4; when two or more Q when two or more Q Az represents a q+1 valent residue of a ring represented by formula (X): wherein each of Z R when two or more R when two or more Az groups exist, the Az groups may be the same or different; W represents a cyano group, a cyano-substituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms, or a cyano-substituted heterocyclic group having 5 to 30 ring atoms, provided that the cyano-substituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms and the cyano-substituted heterocyclic group having 5 to 30 ring atoms may be further substituted by a substituent other than a cyano group, and when two or more W groups exist, the W groups may be the same or different.
