摘要：

A new aggregation-induced emission (AIE) luminogen is obtained by dimerizing acridin-9(10H)-one (Ac), an aggregation-caused quenching (ACQ) effect monomer via an N & horbar;N bond and forming 9H,9 ' H-[10,10 '-biacridine]-9,9 '-dione (DiAc) with D2d symmetry. The quenching of DiAc in solution is ascribed to the enhanced basicity promoting hydrogen bonding and then a hydrogen abstraction (HA) reaction and/or an unallowed transition in frontier orbitals with the same symmetry facilitating intersystem crossing. It is found that emissive Ac is one product of the non-emissive DiAc solution in the H...
