sparked recent interest in new syntheticroutes to tertiary arsines that avoid hazardous arsenous chloride reagents. However, safer methods for the synthesis of lesser explored arsine heterocycles, especially those containing As–C(sp3) bonds, remain lacking. We demonstrate for the first time that bench stable, less hazardous, arylarsine(III) oxides are effective substitutes for their corresponding chlorides
Tetranuclear cubic copper(I) iodide (CuI) complexes were synthesized by utilizing tertiaryarsine ligands such as triphenylarsine, tri(p-tolyl)arsine, 9-phenyl-9-arsafluorene, and 1-phenylarsolane; except for triphenylarsine, these ligands were prepared by the practical methods that we previously developed. The obtained complexes exhibited intense emission in the crystalline states even at room temperature
四核立方碘化铜(I)配合物是利用叔a配体如三苯基ar,三(对甲苯基)ar,9-苯基-9-sa芴和1-苯基ar烷合成的。除了三苯基ar,这些配体是通过我们先前开发的实用方法制备的。即使在室温下,所获得的络合物在晶态下也表现出强烈的发射。机械发光,温度和激发波长极大地改变了它们的发射颜色。这些配合物是具有砷配体的立方Cu 4 I 4配合物的第一个实例,砷配体表现出刺激响应性和激发波长依赖性发光。
