Carboxylic Anhydride Linkers [Covalent Organic Frameworks (COFs) Linkers]

Carboxylic Anhydride Linkers [Covalent Organic Frameworks (COFs) Linkers] — contains aromatic dianhydrides such as Pyromellitic Dianhydride and Perylenetetracarboxylic Dianhydride that function as planar, electron-rich linker units. The dianhydride structure enables the formation of imide bonds or other condensation bonds when constructing ordered porous network frameworks.

These carboxylic dianhydride linkers are used in the synthesis of Covalent Organic Frameworks (COFs) and porous polyimide materials through condensation reactions with aromatic diamines to form ordered two- or three-dimensional frameworks. Researchers in porous materials and supramolecular chemistry use high-purity variants, including those purified by sublimation, for optoelectronic and gas storage applications.

Product selection should consider the purity level, including options that have been purified by sublimation, as linker purity strongly affects the regularity of the crystallinity of the resulting framework. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
