多核金属配合物在合成方面取得了巨大的进步,它们多才多艺的结构特征,新兴的应用。这里,我们通过采用共面堆叠的环基烷基衍生的假双花的桥接配体设计,概念化了环基烷基金属络合物中的金属到金属距离调制,-ortho,-meta,和与N-接枝的对位结构异构体,O-,和含P的螯合物,其允许以彼此的距离限定和空间取向的关系安装不同的(杂)金属部分。金属与金属的距离调制和固有的跨环\“通过空间\”π-π电子相互作用通过共面堆叠的苯环在环基衍生的配合物以及其特定的立体化学结构特征(平面手性元素)是关键因素,有助于结构-性质关系的调整,从催化和新兴材料应用的协同作用的角度来看,这是非常核心的。
Multinuclear metal complexes have seen tremendous progress in synthetic advances, their versatile structural features, and emerging applications. Here, we conceptualize Metal-to-Metal distance modulation in cyclophanyl metal complexes by bridging ligand design employing the co-facially stacked cyclophanyl-derived pseudo-geminal, -ortho, -meta, and -para constitutional isomers grafted with N-, O-, and P- containing chelates that allow the installation of diverse (hetero)metallic moieties in a distance-defined and spatially-oriented relation to one another. Metal-to-Metal distance modulation and innate transannular \"through-space\" π-π electronic interactions via the co-facially stacked benzene rings in cyclophanyl-derived complexes as well as their specific stereochemical structural features (element of planar chirality) are crucial factors that contribute to the tuning of structure-property relationships, which stand at the very center from the perspective of cooperative effects in catalysis as well as emerging material applications.
