| Abstract: | The mixed-valence compound [CuI(dmp)2][CuII(hfac)3] with dmp=2,9-dimethyl-1,10-phenanthroline and hfac−=hexafluoroacetylacetonate has been synthesized and structurally characterized by X-ray crystallography. The MV interaction has been examined by emission spectroscopy. The phosphorescence of [CuI(dmp)2]+ is completely quenched. It is suggested that this quenching takes place by excited state electron transfer from Cu(I) to Cu(II). |
