混价Au(I)/Au(III)共晶化合物的结构和光谱研究
首发时间:2020-05-22
摘要:Au???Au相互作用对超分子化合物的结构及光学行为的影响不容小觑,相关报道多以Au(I)???Au(I)为主却忽视了Au(I)???Au(III)相互作用的研究价值。本文根据金的配位习性合成了线型[Au(CH3NC)2]+和平面型[Au(bdt)2]-前驱体,通过共晶手段获得两例混价Au(I)/Au(III)化合物,为研究Au(I)???Au(III)相互作用对超分子堆积和分子发光以及后续的原位"压"致变色提供重要参考。

Structure and spectroscopic investigation of mixed-valence Au(I)/Au(III) cocrystallized complexes
Abstract:The influence of Au???Au interaction on the structure and spectroscopy of supramolecular compounds is of importance. Most of the relevant reports focus on Au (I)???Au (I), but ignore the research value of Au(I)???Au(III) interaction. In this paper, linear [Au(CH3NC)2]+ and planar [Au(bdt)2]- precursors have been synthesized step by step according to the coordination habit of gold. Two mixed-valence Au(I)/Au(III) complexes have been obtained by means of cocrystallization, which provides an important reference for the study of Au(I)???Au(III) interaction on luminescence of supramolecules and the subsequent in-situ "pressure" induced piezochromism.
