Abstract

A new tetrahedral coordination cage M12L6 was prepared from a linear dipyrimidine ligand (L) and cis-protected palladium(II) (M). This cage showed unprecedented host-guest chemistry where the cationic host accommodated a cationic guest despite 24+ charges on the host framework. The unusual cation-cation host-guest chemistry is described by a unique onionlike shell structure of the host-guest complex where two cationic spheres are mediated by an anionic sphere of a counteranion assembly.

摘要

一种新的四面体配位笼M12L6由线性二嘧啶配体（L）和顺式保护的钯（II）（M）制备而成。该笼展现出前所未有的主客体化学性质，尽管主体框架上带有24个以上的正电荷，但阳离子主体仍能容纳阳离子客体。这种不同寻常的阳离子-阳离子主客体化学性质由主客体复合物独特的洋葱状壳层结构来描述，其中两个阳离子球体由抗衡离子聚集体的阴离子球体介导。
