Two hexaarylbenzenes having six pyridine substituents (LH and LM) were prepared and six corresponding coordination complexes with copper(i) chloride were synthesized. Monomeric complexes (1, 2a and 2b) and 1D coordination polymers (3, 4 and 5) were synthesized via the judicious concentration control of copper(i) ions and characterized fully by X-ray crystal analysis. The binding modes of the ligands to copper(i) ions in the coordination polymers were dependent on steric effects and solvents to determine the morphology of the coordination polymers. More interestingly, dynamic behaviours of the monomeric complexes (1, 2a and 2b) in the solution phase were studied to show potential applications of molecular machines with fluxional motions.
合成了两种具有六个吡啶取代基的六芳基苯（LH 和 LM），并合成了六种相应的与一价铜配合物。通过一价铜离子浓度的合理控制，合成了单体配合物（1、2a 和 2b）和 1D 配位聚合物（3、4 和 5），并通过 X 射线晶体分析进行了充分的表征。配位聚合物中配体与一价铜离子的结合方式取决于空间位阻和溶剂，以确定配位聚合物的形态。更有趣的是，研究了单体配合物（1、2a 和 2b）在溶液相中的动态行为，以展示具有通量运动的分子机器的潜在应用。
