“…The geometries of the complexes in ground state were fully optimized using density functional theory (DFT) with the B3LYP hybrid exchange correlation functional. [33] The DFT (TD-DFT) calculations were performed on the subsequent structures by using the same method to understand the absorption transition. Through these calculations, a ''double-ζ'' quality basis set (LANL2DZ) was employed for Cu and I atoms, and C, H, O, N and P were described by 6-31G(d,p) basis set.…”

Four mono-and two dinuclear Cu(I) complexes were synthesized based on novel 4-diphenylphosphino-benzimidazole (P^N) derivatives, and their structures as well as photophysical properties were systematically investigated. X-ray crystallographic analysis reveals that the Cu(I) centers adopt pseudotetrahedral geometries. All the complexes in powder at 293 K display bright phosphorescence with the highest photolumines-cent quantum yield of 37.6 %. The emission maxima could be finely tuned from 514 to 592 nm by the methoxy substituent on the N^P ligands. The combined experimental results at different temperature (293 K and 77 K) and theoretical studies suggest that the nature of the emissive states can be mainly assigned as a dominant charge-transfer character involving major components of 3 (M + X) LCT transitions.
