| Abstract: | A novel diimine Cu(I) complex Cu(ABPQ)(DPEphos)]BF4 ABPQ and DPEphos are acenaphtho1,2-b]bipyrido2,3-h;3,2-f]quinoxaline and bis(2-(diphenylphosphanyl)phenyl) ether, respectively] is synthesized, and its photophysical properties are experimentally and theoretically characterized. The emission bands centered at ca. 400/470 and 550 nm of Cu(ABPQ)(DPEphos)]BF4 are attributed to the ligand-centered π → π* transition and the metal-to-ligand charge transfer dπ(Cu) → π*(N–N) transition, respectively. The luminescence quantum yield of Cu(ABPQ)(DPEphos)]BF4 in CHCl3 is found to be about five times higher than that of Cu(Phen)(DPEphos)]BF4. |
