  A general and highly regioselective synthetic protocol for structurally diverse N-heteroaryl-fused phenanthridines has been developed. Varieties of fluorescence molecules comprising imidazole-fused, benzoimidazole-fused, indole-fused and pyrrole-fused phenanthridines were obtained by this modular approach, some of which exhibit excellent blue-emitting performance, high quantum yields, long fluorescence lifetimes, interesting electrochemical properties, and thermal stabilities.

  Starting from 2-arylbenzimidazoles and aryl halides, an efficient palladium-based catalytic method for the synthesis of benzimidazole-fused phenanthridines has been developed. This reaction sequence comprises intermolecular C-H arylation and intramolecular aerobic oxidative C-H amination, involving the rupture of two C-H bonds, one C-X bond, and one N-H bond in one pot. The Pd-II-Pd-IV-Pd-II and Pd-II-Pd-0-Pd-II catalytic cycles work together under the reported conditions to generate phenanthridines with diverse substituents.

  An efficient protocol has been developed that uses sequential N-arylation and intramolecular C–H coupling for the construction of azole-fused phenanthridine heterocycle derivatives in good yields. This new method allows the one-pot synthesis of polysubstituted complex molecules from readily available benzo[d]imidazoles and 1,2-dibromobenzenes.
