Claim:
An imidazole ring-containing compound, comprising: where A is selected from the group consisting of B is selected from the group consisting of where X is; X′ is selected from the group consisting of CR and N; where each of R 1 through R 5 , R 11 , and R 12 is independently selected from the group consisting of a hydrogen, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C1-C30 alkoxy group; a substituted or unsubstituted C4-C30 cycloalkyl group, a substituted or unsubstituted C2-C30 aryl group, a substituted or unsubstituted C6-C30 aryloxy group, a substituted or unsubstituted C2-C30 heteroacryl group, a substituted or unsubstituted C2-C30 heteroaryloxy group, a substituted or unsubstituted C6-C30 condensed polycyclic group, an amino group, a substituted or unsubstituted C1-C30 alkylamino group, a substituted or unsubstituted C6-C30 arylamino group, a cyano group, a nitro group, a hydroxy group, a halogen atom, a substituted or unsubstituted C6-C30 arylsulfonyl group, and a substituted or unsubstituted C1-C30 alkylsulfonyl group, where adjacent groups among R 1 through R 5 , R 11 , and R 12 can combine together to form a substituted or unsubstituted C 2 -C 30 saturated or unsaturated ring; where each of R′ and R″, which are monosubstituted or multi-substituted groups, is selected from the group consisting of a hydrogen, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C1-C30 alkoxy group; a substituted or unsubstituted C4-C30 cycloalkyl group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C6-C30 aryloxy group, a substituted or unsubstituted C2-C30 heteroacryl group, a substituted or unsubstituted C2-C30 heteroaryloxy group, a substituted or unsubstituted C6-C30 condensed polycyclic group, an amino group, a substituted or unsubstituted C1-C30 alkylamino group, a substituted or unsubstituted C6-C30 arylamino group, a cyano group, a nitro group, a hydroxy group, a halogen atom, a substituted or unsubstituted C6-C30 arylsulfonyl group, and a substituted or unsubstituted C1-C30 alkylsulfonyl group, and where R′ and R″ can combine together to form a saturated or unsaturated ring.
