The Front Cover shows the structure of a new polymerizable Ni‐Salphen complex determined by X‐ray crystallography, where the nickel center displays 1 : 1 and 1 : 2 host‐guest stoichiometries toward anions, both coexisting in solution. The three random coil conformations represented for the polymer version are triggered by anion recognition through the metal as well. Superior association constants, larger absorbance upon guest‐recognition and only 1 : 2 stoichiometry were then reached in UV‐Vis titrations. More information can be found in the Full Paper by G. A. Zelada‐Guillén, M. V. Escárcega‐Bobadilla, and co‐workers.

包含镍二氮烯配合物的丙烯酸聚合物：超分子和大分子系统的一种方法

前盖显示了通过X射线晶体学测定的新型可聚合Ni-Salphen配合物的结构，其中镍中心对阴离子的主客体化学计量比为1：1和1：2，两者都共存于溶液中。聚合物形式表示的三个无规卷曲构象也由通过金属的阴离子识别触发。然后，在紫外可见分光光度法中达到了优异的缔合常数，宾客识别时的更大吸光度和仅1：2的化学计量比。可以在GAZelada-Guillén，MVEscárcega-Bobadilla和同事的论文全文中找到更多信息。
