Controllable Synthesis of Covalent Porphyrinic Cages with Varying Sizes via Template-Directed Imine Condensation Reactions

Covalent
porphyrinic cages (CPCs) have been a target of interest
for years. In this paper, we report the design and synthesis of two
CPCs in which the cofacial porphyrins have a distance of 7.66 and
11.96 Å via template-directed imine condensation reactions and
through the selective choice of templating linker and diamine length.

共价卟啉笼（Covalent Porphyrinic Cages, CPCs）多年来一直是广受关注的研究对象。本文报道了两例该类笼状结构的设计与合成：通过模板导向亚胺缩合反应，并结合对模板连接基与二胺链长的选择性调控，使其中面对面排布的卟啉环间距分别为7.66 Å与11.96 Å。
