Claim:
A material comprising a compound represented by the following general formula (1): wherein Ar 1 to Ar 4 each represent a p-phenylene or m-phenylene; R 1 to R 8 each independently represent a hydrogen atom, a phenyl group, or a group represented by Cz below; Cz represents a group expressed by the following general formula (2a): wherein A represents a single bond and R 14 to R 15 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 40 carbon atoms, a substituted or unsubstituted heterocyclic group having 3 to 40 ring atoms, a substituted or unsubstituted alkoxy group having 1 to 40 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group having 6 to 40 ring carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 40 carbon atoms, a substituted or unsubstituted aralkyl group having 7 to 40 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 40 carbon atoms, a substituted or unsubstituted alkylamino group having 1 to 40 carbon atoms, a substituted or unsubstituted arylamino group having 6 to 40 carbon atoms, or a substituted or unsubstituted aralkylamino group having 7 to 40 carbon atoms; provided that, when all of Ar 1 to Ar 4 each represent p-phenylene in the general formula (1), at least one of R 1 to R 8 represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 40 ring carbon atoms, or the above group represented by Cz.
