Abstract

A novel, interlocked, self-assembled (M(2)L(2))(2) molecular architecture was constructed from an arene-Ru acceptor and a 1,4-di(pyridin-4-yl)buta-1,3-diyne donor. Two M(2)L(2) units, with cavities of ~7.21 Å, spontaneously interlock, with one unit encapsulating a twin in a non-catenane fashion. The dimeric host-guest complex thus formed is unique among two-dimensional self-assemblies and is stabilized by π-π interactions between the M(2)L(2) units.

摘要

一种新型的互锁、自组装的(M(2)L(2))(2) 分子结构是由芳烃-Ru 受体和 1,4-二(吡啶-4-基)丁-1,3-二炔供体制备的。两个 M(2)L(2) 单元,具有约 7.21 Å 的空腔,自发地互锁,其中一个单元以非套索的方式封装一对孪生。由此形成的二聚体主体-客体配合物在二维自组装中是独特的,并且通过 M(2)L(2) 单元之间的 π-π 相互作用得到稳定。
