本文描述了一类新的同手性盐基无限配位聚合物（icp），并发现了一种新的、伪可逆的溶剂诱导结晶过程。溶剂，在这种情况下，甲醇，通过改变周围的金属桥接的配合物的金属-salen部分的配位环境诱导这种转变。这种转变使我们能够使用x射线方法对晶体产品进行结构表征，并通过光谱比较更好地了解其衍生的无定形ICP颗粒的连通性和结构。
This paper describes a new class of homochiral salen-based infinite coordination polymers (ICPs) and the discovery of a novel and pseudo-reversible solvent-induced crystallization process. The solvent, methanol in this case, induces such a transformation through a change in the coordination environment around the metal bridging the metallo-salen portion of the complex. This transformation has allowed us to use X-ray methods to structurally characterize the crystalline product and through spectroscopic comparisons better understand the connectivity and structure of the amorphous ICP particles from which it is derived.
