Structural and photophysical study of copper iodide complex with P^N or P^N^P ligand

Abstract

A series of CuI complexes with P^N or P^N^P ligand showing rich structural and photophysical properties were synthesized and studied.

Site-Selective Benzannulation of N-Heterocycles in Bidentate Ligands Leads to Blue-Shifted Emission from [(P^N)Cu]2(μ-X)2 Dimers

“…Cu2X2 cores supported by P^N ligands were found to have strong CT character, in particular (Cu+X)LCT, 18,21,39 and so, range-separated hybrids were employed for CTtype transitions to ensure physically meaningful estimates of the transition energies. 40 Basis sets 6-31G(d,p) 57-58 on H, C, N and P; m6-31G(d) 59 on Cu; and LANL2DZ with effective core potential 60-62 on I were employed for all calculations.…”

Predesigned synthesis of dinuclear to unusual hexanuclear to 1D coordination polymer of Cu(I)-halides and their and photophysical properties

“…Cu I -complexes such as discrete monomers, dimeric clusters and 1D coordination chains have been reported by several research group [25][26][27][28]. Most of the complexes contain halide as the counter anion in combination with triphenylphosphine and N-heterocyclic molecules as ligand.…”

Copper(I) Phosphinooxazoline Complexes: Impact of the Ligand Substitution and Steric Demand on the Electrochemical and Photophysical Properties

“…Particularly, the combination of a N ‐heteroaryl moiety, which possesses a wide range of tunable electronic properties and a soft phosphine donor seems promising . Several Cu I complexes based on different types of P^N ligands, mainly as multinuclear cuprous halide complexes, have already been prepared and investigated . In these examples the phosphine unit is either directly bound to the N ‐heteroaryl moiety (e.g., 2‐(diphenylphosphino)‐pyridine or 8‐(diphenylphosphino)‐quinoline) or connected via an aliphatic spacer (e.g.…”

Consequently, the previous examples are typically bridging or only monodentate ligands due to the small bite angle .…”
