In recent years, increasing efforts have been devoted to designing new functional stimuli-responsive supramolecular assemblies. Here, we present three isomeric supramolecular coordination complexes consisting of a Pd2L4 stoichiometry. As shown by NMR, CD and X-ray studies, as well as DFT calculations, these complexes form cage-like structures by chiral self-sorting. Photochromic ligands derived from first generation molecular motors enable light-driven interconversion between the three isomers. Two of the isomers were able to form host–guest complexes opening up new prospects toward stimuli-controlled substrate binding and release.

基于拥挤烯烃的手性自分选光响应配位笼
近年来，人们越来越多地致力于设计新的功能性刺激响应超分子组件。在这里，我们提出了由 Pd 2 L 4化学计量组成的三种异构超分子配位配合物。 NMR、CD 和 X 射线研究以及 DFT 计算表明，这些配合物通过手性自排序形成笼状结构。来自第一代分子马达的光致变色配体能够实现三种异构体之间的光驱动相互转化。其中两种异构体能够形成主客体复合物，为刺激控制的底物结合和释放开辟了新的前景。
