Patent ID: 6936189

Claim:
A cyclic tertiary amine compound represented by a formula (1), wherein A represents an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted heterocyclic group, and four As may be all the same or partly different; Y 1 represents a substituted or unsubstituted arylene group, or a substituted or unsubstituted heterocyclic divalent group; Y 2 represents a group represented by a formula (2), a substituted or unsubstituted condensed ring arylene group, or a substituted or unsubstituted heterocyclic divalent group, wherein R 1 to R 8 in the formula (2) independently represents a hydrogen atom, a halogen atom, an alkyl or alkoxy group having 1 to 6 carbon atoms, an aryl group or a heterocyclic group; and Z represents single bond, an arylene group, —CH 2 —, —CH═CH—, —C≡C—, —C(CH 3 ) 2 —, —CO—, —O—, —S— or —SO 2 —, with the proviso that when Y 1 represents a phenylene group, Y 2 represents a group represented by the formula (2), a substituted condensed ring arylene group, an unsubstituted 1,4-naphthylene, an unsubstituted fluoren-1,4-diyl, an unsubstituted anthracen 1,4-diyl, or a substituted or unsubstituted heterocyclic divalent group.
