摘要
构建稳定的共价有机框架(COFs)用于各种应用是非常需要的。本文合成了一种新的二维(2D)卟啉基sp2碳共轭COF (Por-sp2c-COF),该COF采用重叠AA堆叠结构,brunauer - emmet - teller比表面积为689 m2 g−1。由于C=C键,Por-sp2c-COF在各种条件下都表现出很高的化学稳定性,即使在9 m HCl和9 m NaOH溶液等恶劣条件下也是如此。有趣的是,Por-sp2c-COF可以作为一种无金属的非均相光催化剂,用于可见光诱导的胺氧化生成亚胺。更重要的是,与亚胺连接的Por-COF相比,Por-sp2c-COF的固有结构使其作为光催化剂具有可重复使用和高光催化性能等优点。这清楚地表明,sp2碳连接的2D COFs可以为多相光催化提供一个有趣的平台。
Designed Synthesis of a 2D Porphyrin-Based sp2 Carbon-Conjugated Covalent Organic Framework for Heterogeneous Photocatalysis
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 sp2 carbon-conjugated COF (Por-sp2c-COF), which adopts an eclipsed AA stacking structure with a Brunauer—Emmett—Teller surface area of 689 m2 g−1. Owing to the C=C linkages, Por-sp2c-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-sp2c-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 imine-linked Por-COF, the inherent structure of Por-sp2c-COF equips it with several advantages as a photocatalyst, including reusability and high photocatalytic performance. This clearly demonstrates that sp2 carbon-linked 2D COFs can provide an interesting platform for heterogeneous photocatalysis.
