纳米化学的一个方面，这已经引起了极大的关注，是从金属络合物的自组装形成一维（1D）纳米纤维。基于化合物的设计，从这种复合物制造纳米结构，其显示出合作功能，目前被视为纳米材料领域内的重要目标之一。在这篇综述中，我们描述了允许调节金属-三唑配合物之间分子间相互作用的方法，无论是在溶液、薄膜还是液晶中。亲脂性三唑配体1（C12 OC 3 Trz）被设计成使得醚键存在于烷基链部分中。这种柔性的醚键提高了该配体的各种配合物（包括[Co II（1）3] Cl 2和[Fe II（1）3] Cl 2）在有机介质中的溶解度，也提高了烷基链的堆积效率。一维配位体系的这种亲脂性修饰可以导致动态结构转变，从而产生独特的溶液性质，包括热定型凝胶状网络、客体诱导的结构变化、电化学转变和自旋交叉状态切换。一维金属配合物的超分子化学在其范围和潜在应用方面是前所未有的，希望本文的研究将提供新的信息，以促进动态超分子器件的进一步研究。
An aspect of nanochemistry, which has attracted significant attention, is the formation of one-dimensional (1D) nanofibers from the self-assembly of metal complexes. The fabrication of nanoarchitectures from such complexes, based on the design of compounds, which show cooperative functionalities, is currently seen as one of the important goals within the field of nanomaterials. In this review, we describe methods that allow the tuning of the intermolecular interactions between metal-triazole complexes, whether in solution, thin films or liquid crystals. The lipophilic triazole ligand 1 (C 12 OC 3 Trz) has been designed such that an ether linkage exists in the alkyl chain moiety. This flexible ether linkage enhances the solubility of various complexes of this ligand (including [Co II (1) 3] Cl 2 and [Fe II (1) 3] Cl 2) in organic media and also improves the packing efficiency of the alkyl chains. Such lipophilic modifications of 1D coordination systems can result in dynamic structural transformations leading to unique solution properties, including heat-set gel-like networks, guest-induced structural changes, electrochemical transformations and spin crossover state switching. The supramolecular chemistry of 1D metal complexes is unprecedented in its scope and potential applications, and it is hoped that the studies presented herein will provide new information to promote further investigation of dynamic supramolecular devices.
