Collection: Covalent Organic Frameworks (COFs) Linkers

Covalent Organic Frameworks (COFs) Linkers — a collection of bifunctional and multifunctional building blocks such as aldehydes, amines, boronic acids, and carboxylic anhydrides that serve as connecting units in the construction of covalent organic frameworks (COFs). The combination of reactive groups in these compounds enables directed formation of covalent bonds into crystalline porous structures.

Covalent Organic Frameworks (COFs) Linkers are used by materials chemists and porous materials researchers to assemble two- and three-dimensional frameworks through condensation reactions, such as imine formation between amine and aldehyde groups, or boronate ester bonds between boronic acids and diols. Linkers such as benzene-1,3,5-tricarbaldehyde and triazine derivatives are widely used as structural nodes in the synthesis of gas storage, catalysis, and molecular separation materials.

Example products in this collection: TCI H0172 7803-57-8 Hydrazine Monohydrate, TCI B6003 3163-76-6 Benzene-1,3,5-tricarbaldehyde, TCI X0061 622-75-3 p-Xylylene Dicyanide, TCI B6401 36997-31-6 Benzene-1,3,5-tricarbohydrazide, TCI T4344 1128-13-8 2,3,5,6-Tetraaminocyclohexa-2,5-diene-1,4-dione, TCI B6576 135822-72-9 [2,2'-Bipyridine]-5,5'-dicarbaldehyde, TCI T4341 2130745-76-3 4',4''',4'''''-(1,3,5-Triazine-2,4,6-triyl)tris[([1,1'-biphenyl]-4-amine)], TCI B6577 13140-82-4 1,1'-([1,1'-Biphenyl]-4,4'-diyl)diurea.

Linker selection should consider the geometry and number of reactive functional groups (linear, triangular, or hexagonal), purity level, and reactivity compatibility with the paired linker so that covalent framework formation proceeds in a directed manner. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
