A new covalent organic framework (COF) based on imine bonds was assembled from 2-(4-formylphenyl)-5-formylpyridine and 1,3,6,8-tetrakis(4-aminophenyl)pyrene, which showed an interesting dual-pore structure with high crystallinity. Postmetallation of the COF with Pt occurred selectively at the N donor (imine and pyridyl) in the larger pores. The metallated COF served as an excellent recyclable heterogeneous photocatalyst for decarboxylative difluoroalkylation and oxidative cyclization reactions.
一种基于亚胺键的新型共价有机框架（COF）由2-（4-甲酰基苯基）-5-甲酰基吡啶和1,3,6,8-四（4-氨基苯基）芘组装而成，其具有有趣的双孔结构且结晶度高。该COF与铂的后金属化反应选择性地发生在较大孔中的氮供体（亚胺和吡啶基）处。金属化的COF作为一种优异的可回收多相光催化剂，用于脱羧二氟烷基化和氧化环化反应。
