Alfa Chemistry Announces Offerings of COFs Linkers to Support Organic Frame Material Research

1. Alfa Chemistry Announces Offerings of COFs Linkers to Support Organic Frame Material Research The past decade has seen an increasing interest in covalent organic frameworks (COFs) due to their enormous potential design space offered by the atomically precise spatial assembly of molecular organic building blocks. In January 2021, Alfa Chemistry announces the offering of COF linkers, to support research on organic frame materials and to meet the growing demand. A special website is built for customers to find COFs linkers as easily as possible. COFs are now at the forefront of modern porous materials research. They represent an intriguing class of crystalline appropriately functionalized organic molecules are linked with an atomic level precision to give extended periodic structures. Such potentials can make COFs have unprecedented properties and applications. porous materials, where “COFs stand out among various porous polymers by virtue of their crystallinity, diverse framework topologies and accessible pore systems. Comparing to other porous materials, COFs are superior for their stability,” says a senior scientist from Alfa Chemistry. “COFs are built from organic linkers via slightly reversible condensation reactions. A widely used linker core for COFs is phthalocyanine, either in its H‐form or complexed with a metal.” It is very challenging to produce COFs that are simultaneously crystalline, stable, and functional as reversible bond formation is one of the prime prerequisites for the crystallization of COFs. However, with the advances in COF field, new strategies have surfaced, which can help to obtain both stable and crystalline COFs. COF linkers are very important because their geometry and functionalization were proven to be an important determining factor for the crystallinity of the COF. Naphthalene‐2,6‐diyldiboronic (ethyne‐1,2‐diylbis(4,1‐phenylene))diboronic acid (EDPDDA) as usd as COF linkers. At Alfa Chemistry, many more COF linkers are readily available, such as 4,4'-oxybisbenzenamine (CAS 101-80-4), 100516-61-8), 1,3,5-Benzenetricarbonitrile Tetrakis(4-bromophenyl)methane (CAS diethynylbenzene (CAS 2,3,6,7-tetramethoxy-9,9-dimethyl-9H-fluorene 3,3'-Dimethylbiphenyl-4,4'-diamine (CAS 119-93-7), etc. acid (NPDA) and Hexaethynylbenzene (CAS 105309-59-9), (CAS 10365-94-3), bisamine 1141727-54-9), 1176891-87-4), (CAS For more information about Alfa Chemistry’s COF linker products, please visit https://mof.alfa-chemistry.com/products/cofs-linkers-722.html.
