Observation of photoluminescence in a CuI(amino N)2(imino N)2 chromophore at room temperature and 77 K

A moderately air stable CuI(amino N)2(imino N)2 chromophore having a Cu(II/I) potential of 0.12 V vs SCE is isolated using a tetradentate N-donor ligand and characterised structurally by X-ray crystallography. It is found to be photoluminescent in fluid solution at room temperature as well as in frozen solution at 77 K.
