A Sustainable Strategy for Synthesizing Conjugated Porous Organic Frameworks
Abstract
In recent years, there has been a surge of interest in conjugated porous organic frameworks (CPOFs) due to their exceptional properties. CPOFs possess a range of appealing characteristics including a large surface area, intrinsic porosity, a modular pi -conjugated molecular system, and high stability under harsh conditions. Nevertheless, the state-of-the-art synthesis methods for CPOFs present significant challenges and hindering their widespread use beyond the laboratory. The currently available methods used in the CPOFs synthesis rely on using expensive metal complexes along with building blocks with specific functional groups, specific additives, and high temperatures. Consequently, the existing techniques yield solid CPOFs containing remnants of noble metals and lacking versatile substituents such as -Br and -I. These limitations restrict the potential multi-functional properties of CPOFs. To address these concerns, this project proposes a pioneering synthetic route, namely the 2D bismuth (bismuthene) catalyzed photoredox C-H arylation-mediated strategy, for the facile synthesis of CPOFs with unexplored properties. By employing this unique approach, the drawbacks of the currently available methods used in the synthesis of CPOFs can be overcome. The photoredox-mediated strategy facilitates the sustainable synthesis of various CPOFs, featuring adjustable functional properties (e.g., porosity, bandgap, and hydrophilicity). Furthermore, for the first time, this synthetic approach enables the synthesis of CPOFs bearing -Br or -I functional groups. These groups have the potential to significantly impact the optoelectronic and photochemical properties of CPOFs. To showcase the versatility and synthetic power of the method, a wide range of rationally designed CPOFs will be synthesized. The resulting materials have high potential to be used in diverse fields within the context of establishing a methodology-structure-property relationship. Undoubtedly, this methodology represents a breakthrough in the controlled fabrication not only of CPOFs but also other carbon-based nanomaterials. Its implementation is poised to revolutionize the field and open up new horizons in the development of advanced functional porous materials.
