Designed Synthesis of a 2D Porphyrin‐Based sp 2 Carbon‐Conjugated Covalent Organic Framework for Heterogeneous Photocatalysis
Wuhan University · University of Science and Technology Beijing
Abstract
Abstract The construction of stable covalent organic frameworks (COFs) for various applications is highly desirable. Herein, we report the synthesis of a novel two‐dimensional (2D) porphyrin‐based sp 2 carbon‐conjugated COF (Por‐sp 2 c‐COF), which adopts an eclipsed AA stacking structure with a Brunauer—Emmett—Teller surface area of 689 m 2 g −1 . Owing to the C=C linkages, Por‐sp 2 c‐COF shows a high chemical stability under various conditions, even under harsh conditions such as 9 m HCl and 9 m NaOH solutions. Interestingly, Por‐sp 2 c‐COF can be used as a metal‐free heterogeneous photocatalyst for the visible‐light‐induced aerobic oxidation of amines to imines. More importantly, in comparison to…
