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.
