Ready-made crystalline porous polymers, perfect for use where their high thermal and chemical stability makes a difference.

Browse COFs

Covalent organic frameworks (COFs) are a class of organic, crystalline porous polymers constructed from light elements – principally carbon, nitrogen, oxygen and hydrogen – linked by strong covalent bonds into extended two- or three-dimensional networks. Uniquely combining properties difficult to achieve simultaneously in other material classes: high surface area; atomically precise pore geometry; low density; exceptional chemical tunability; and, critically, the absence of metal centres, they are attractive for applications where cost, sustainability or biocompatibility is a priority.

Fluorochem’s range of COFs spans both pre-formed framework materials found here and the monomer building blocks used in their synthesis, covering the principal linkage chemistries that define the field.

Imine-linked COFs: Schiff-base condensation remains the most widely employed COF-forming reaction, delivering crystalline frameworks with good stability and straightforward synthetic accessibility. Our catalogue includes COF-366 (1381930-10-4), COF-42 (1314877-67-2), TPB-TP-COF (1262433-88-4), TPA-COF (1244037-89-5), TTI-COF (2000996-35-8), LZU-5, and Py-Py-COF (2185790-08-1), spanning square, hexagonal, and kagome topologies, built from aldehyde and amine monomers, including porphyrin, pyrene, triphenylamine and triazine nodes.

β-Ketoenamine COFs: Reaction of 1,3,5-triformylphloroglucinol (TFP) derivatives with primary amines yields irreversible β-ketoenamine linkages with markedly superior chemical stability compared to their imine counterparts. These retain crystallinity in acidic, basic and aqueous media. DAAQ-TFP COF (1477485-46-3) and TpPa2 (1414350-38-1) represent this important family, with the DAAQ variant attracting particular interest in electrochemical energy storage due to its anthraquinone redox units (DeBlase et al., JACS, 2013).

Imide and other linkages: PI-COF-1 (286831-92-3) and PI-COF-2 (932735-93-8) introduce polyimide connectivity, offering exceptional thermal stability up to ~500 °C. NT-COF (1227264-02-9), TTO-COF (2417140-95-3), and COF-V (2065232-77-9) extend the portfolio further, covering triazine and vinyl-functionalised frameworks relevant to photocatalysis and semiconducting applications.

For researchers building their own frameworks, we supply a broad range of aldehyde and amine monomers – triazine-core dialdehydes, phloroglucinol-derived trialdehydes, tetraamine porphyrins, pyrene tetramines and bipyridyl diamines – enabling systematic linker variation and topology screening.
