Enhancement of the Intrinsic Fluorescence of Acridine and its Induced Circularly Polarized Luminescence (CPL) in Ionic Two-Coordinate Coinage Metal Complexes

Enhanced blue fluorescence of acridine is achieved in carbene–M–acridine ionic complexes, where M is Cu( i ) and Ag( i ), approaching 50%. With the help of chiral counter ions, circularly polarized fluorescence of acridine is induced in crystalline state.
