The preparation and the r.t. luminescence of the complexes [Cu(binap)(2)](+) and [Cu(binap)1](2) with binap = 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl are reported. The lowest-energy excited state of [Cu(binap)(2)](+) is an IL pi pi state of the binaphthyl chromophore. The luminescence of the cation consists of a fluorescence and a phosphorescence originating from this IL state. In contrast, the dimer (Cu(binap)I[2 is characterized by a I- -> binap LLCT state which occurs at lower energies than the binap IL state. The dimer shows only a single emission band. This luminescence is suggested to come from the LLCT triplet. (C) 2008 Elsevier B.V. All rights reserved.
