Dinuclear Rhombic Copper(I) Iodide Complexes with Rigid Bidentate Arsenic Ligands

Abstract

We have recently developed a series of arsenic ligands based on practical synthetic strategies. Herein, three kinds of bidentate arsenic ligands with rigid linkers were selected to construct dinuclear rhombic copper(I) iodide (CuI) complexes, whose structures were analyzed by X-ray crystallography. They had sufficient solubility in organic solvents, and it was confirmed that their coordination forms were kept in the solutions. Intense solid-state emissions were observed even at room temperature, and the emission colors were varied from yellow to red by the ligands.

Robust and highly emissive copper(i) halide 1D-coordination polymers with triphenylarsine and a series of bridging N-heteroaromatic co-ligands

“…1c). 10 However, the Φs were still low (up to 0.15) in the crystalline state at 298 K, while the stimulus-sensitivity was certainly suppressed. The flexible coordination of arsenic could probably promote non-radiative deactivation through molecular motions.…”

Copper(I)‐Arsine Clusters with a Near‐Unity Phosphorescence Quantum Yield for X‐Ray Scintillation and LED Applications

“…Potentially, arsine/stibine ligands can also improve X-ray scintillation efficiency of the Cu 4 I 4 clusters through higher X-ray absorption ability of As/Sb nuclei compared to N, P, or S nuclei. However, despite the recent progress in studying Cu(I)-arsine emitters by Naka, [47][48][49] Karasik, [50,51] and our groups, [46,[52][53][54] these compounds still remain poorly explored. In particular, they have never been demonstrated in X-ray scintillation or white light LED (WLED) applications.…”

Arsinoquinolines as a Novel Class of Luminophores

“…Quite recently, we reported the copper iodide complex of 8‐(diphenylarsino)quinoline [6f,g] . During the investigation, we accidentally discovered that 8‐(diphenylarsino)quinoline shows phosphorescence.…”
