Summary:Covalent organic frameworks (COFs), constructed by strong covalent bonds based on reticular chemistry, hold great promise in diverse applications. Manipulating COFs with desired functional properties is of paramount significance. However, the standard solvothermal synthetic methodologies for COF synthesis do not always allow direct incorporation of functional groups into frameworks, due to the incompatibility with the building blocks or reaction conditions. In this regard, alternative approaches for post-synthetic modification (PSM) on a pre-established network provide an opportunity for tuning the functional properties of COFs while maintaining a fundamental framework structure. This review describes recent advances and scientific challenges in the area of post-synthetic methodologies to tailor the properties of COFs. Two different major PSM techniques, namely, covalent PSM and post-synthetic metal functionalization, will be discussed. This review describes recent advances and scientific challenges in the area of post-synthetic methodologies to tailor the functionalities and properties of COFs.
Bibliography:Dr Arindam Mal completed his Master of Science at Indian Institute of Technology, Kharagpur (India) and PhD from CSIR-National Institute for Interdisciplinary Science and Technology (India). He is currently working as a postdoctoral research scholar of Wuhan University in Prof. Cheng Wang's research group under an international postdoctoral exchange fellowship program. His research focuses on 3D covalent organic frameworks.
Huimin Ding received her BS in Chemistry from Qufu Normal University in 2012. She pursued her PhD study under the supervision of Prof. Cheng Wang at Wuhan University and obtained her PhD degree in 2018, where she is currently carrying out postdoctoral research on 3D covalent organic frameworks.
Dr Cheng Wang obtained his BSc degree (2003) from Wuhan University and his PhD degree (2008) in organic chemistry from Institute of Chemistry, Chinese Academy of Sciences, under the supervision of Professor Deqing Zhang and Academician Professor Daoben Zhu. Following postdoctoral research with Professor Sir J. Fraser Stoddart in Northwestern University, he returned to China on March 2012 and started his new position as a full professor at College of Chemistry and Molecular Sciences, Wuhan University. His research focuses on functional microporous materials, including covalent organic frameworks and metal-organic frameworks.
