The urea compound has one or more urea moieties comprising: a carbonyl group, or a thiocarbonyl group, and two nitrogen atoms. Each of the two nitrogen atoms connects to a hydrogen atom, an alkyl group, an unsubstituted or substituted aryl group, or an unsubstituted or substituted arylene group. At least one of the nitrogen atoms connects to an unsubstituted or substituted aryl group. |
