Two new photoluminescent homoleptic distorted tetrahedral Cu I N 4 chromophores with Cu II/I potentials of 0.66–0.81 V vs. SCE are isolated by using two unconjugated diimines (2∶1 condensates of R 1 R 2 C O and ethylenediamine; R 1 = Ph, R 2 = H; R 1 = R 2 = Ph) as ligands. ... Cu I N 4 chromophores which exhibit photoluminescence in solution are known only in copper(I) complexes of substituted 1,10-phenanthrolines (1,10-phen). 1,2 Herein we report new ...
