WebCovalent organic frameworks (COFs) are a class of crystalline porous networks that can integrate organic units into ordered skeletons and pores, offering an insoluble and robust platform for exploring heterogeneous catalysts. In this Outlook, we describe a conceptual scheme for designing catalytic COFs to promote various transformations. WebJul 6, 2024 · COFs are a class of synthetic porous organic materials that provide well-structured, confined spaces for selective molecular recognition processes and enhance the reactivity of the hosted molecules. shooting snow hill md

WebApr 13, 2007 · COF structures that contain light elements (B, C, N, and O) should be able to combine the thermodynamic strength of covalent bonds, as those found in diamonds and boron carbides, with the functionality of organic units. Progress in this area has been impeded by longstanding practical and conceptual challenges.
