Abstract: [CuL2]ClO4 (1), where L is a 1:2 condensate of ethylenediamine and benzophenone, displays four MLCT emissions with maxima λem = 617, 583, 549 and 494 nm in poly(methyl methacrylate) matrix at room temperature. Three of these emissions are observed for 1 in methanol glass at 77 K with λem = 473,440 and 412 nm. The origins of these emissions are investigated by Extended  Huckel calculations on [CuL2]+ at the crystallographically determined geometry.
