We report a general, high-yielding method for the synthesis of water-soluble complexes, which is based upon the weak-link approach to supramolecular coordination chemistry. Specifically, we have utilized oligomeric ethylene glycol functional groups appended to the aryl groups of the diphenylphosphine moieties to achieve solubility. Small molecules or halide ions can be used to expand these complexes into larger, more flexible macrocyclic structures. The realization of this approach should allow for the preparation of allosteric biomimetic structures which can be used in aqueous media.
我们报道了一种通用的、高产率的水溶性配合物合成方法，该方法基于超分子配位化学的弱连接方法。具体而言，我们利用连接到二苯基膦部分芳基上的低聚乙二醇官能团来实现溶解性。小分子或卤离子可用于将这些配合物扩展为更大、更灵活的大环结构。这种方法的实现应该有助于制备可在水性介质中使用的变构仿生结构。
