Abstract
Among the different alternatives for catalysis using metal–organic frameworks (MOFs) or covalent organic frameworks (COFs), photocatalysis has remarkably evolved during the last decade. Photocatalytic reticular materials allowed recyclability and easy separation of catalyst from the product, also reaching the activity and selectivity commonly observed for molecular systems. Recently, photocatalytic MOFs and COFs have been applied to synthetic applications in order to obtain organic molecules of different complexity. However, although a good number of works have been devoted to this issue, an updated comprehensive revision on this field is still needed. The aim of this review was to fill this gap covering the following three general aspects: (1) common strategies on the design of reticular photocatalytic materials, (2) a comprehensive discussion of the photocatalytic organic reactions achieved by the use of COFs and MOFs, and (3) some critical considerations highlighting directions that should be considered in order to make advances in the study of photocatalytic COFs and MOFs.
Highlights
Chemistry has classically addressed questions related to how atoms are linked into molecules and how molecules interact and/or react with each other
The extensive overview of the available literature devoted to organic synthetic applications of photocatalytic systems based on covalent organic frameworks (COFs) and metal–organic frameworks (MOFs) demonstrates the versatility of these materials and their potential for further findings
Some of the most common photocatalytic transformations reported for molecular systems have already been reported for reticular materials, and this review has carefully compiled the recent literature in this respect
Summary
Chemistry has classically addressed questions related to how atoms are linked into molecules and how molecules interact and/or react with each other. The opportunities that reticular chemistry offers are related to the following common features in this family of materials: (a) predesign of building blocks enables control over the frameworks geometries and chemical properties; (b) structural, thermal, and chemical stabilities can be tuned by modulating the strength of bonds that result in the propagation of frameworks, and (c) crystallinity makes possible. The application of these concepts resulted in an extensive structural control and an exceptional library of protocols intended to direct the physical and/or chemical properties that can be used in many applications of frameworks Following these principles, over the last two decades, more than eighty thousand MOFs and hundreds of COFs have been described.
