About this collection
Covalent organic frameworks (COFs) represent a new field of rapidly expanding chemical research that takes direct inspiration from covalent dynamic chemistry, translated to the supramolecular level. The success of linking molecules in two and three dimensions to construct extended and highly ordered framework structures moved the chemistry of COFs beyond mere structures to new concepts and methodologies, highlighting the feasibility of prospective applications.
In this themed issue, Guest Edited by Rahul Banerjee (IISER, Kolkata), Bettina Lotsch (Ludwig Maximilian University of Munich) and William Dichtel (Northwestern University), we would like to spotlight the structure -- property relationships in COFs giving rise to fascinating properties, like separation, ionic and electronic transport, catalytic activity, processability and scalability. These attributes are key to adapting COFs to next-generation applications in energy conversion and storage, catalysis, optoelectronics, biomedicine, and beyond. On a more fundamental level, we would like to revisit the growth of COFs, highlight novel design concepts and identify new development areas for COFs which have the potential to ultimately take COFs from mere lab curiosities to technologically relevant materials.
