simple silver meso‐triarylcorroles and silver β‐octabromo‐meso‐triarylcorroles: the former were described as essentially innocent and the latter as substantially noninnocent. In a first X‐ray absorption near‐edge spectroscopic (XANES) study of ligandnoninnocence in metallocorroles, Ag L3‐edge spectra have now provided direct experimental support for the variable electronic structure of silver corroles
结构,光谱学和DFT研究最近表明,在简单的内消旋银内消旋三芳基甲酚和β-八溴内消旋三芳基银之间的显着电子结构转换:前者被描述为实质上是无害的,而后者被描述为实质上是无害的。在第一个X射线吸收近边缘光谱(XANES)研究中,金属茂化合物中的配体无毒无害,Ag L 3边缘光谱现在已经为银分子的可变电子结构提供了直接的实验支持。
