The aforementioned alkyl group represents a substituted or unsubstituted C1 to C20 alkyl group and may have a linear, branched, or cyclic structure. The aforementioned alkyl group is preferably with a carbon number of 1 to 12, examples of which include a methyl group, a butyl group, a pentyl group, a hexyl group, an octyl group, a decyl group, and a dodecyl group.
The aforementioned aryl group represents a substituted or unsubstituted C6 to C10 aryl group and may be condensed into a ring, examples of which include a phenyl group, a toluyl group, and a naphthyl group.
The aforementioned fluoroalkyl group is preferably a trifluoromethyl group.
The aforementioned alkoxy group represents a substituted or unsubstituted C1 to C20 alkoxy group and may have a linear, branched, or cyclic structure. The aforementioned alkoxy group is preferably with a carbon number of 1 to 12, examples of which include a methoxy group, a butyloxy group, an octyloxy group, a decyloxy group, a dodecyloxy group, an s-octyloxy group, and a benzyloxy group.
The aforementioned heterocyclic group represents a substituted or unsubstituted C6 to C10 nitrogen-containing aromatic heterocyclic group and may be condensed into a ring, examples of which include a pyridine ring, a pyrazine ring, a pyrimidine ring, a pyridazine ring, a triazine ring, and a carbazole ring, with a carbazole ring being preferable.
The aforementioned diarylamino group represents a substituted or unsubstituted C6 to C10 diarylamino group and may be condensed into a ring, examples of which include a diphenylamino group, a ditoluylamino group, and a dinaphthylamino group.
