Benzene-1,3,5-triyltriboronic acid (CAS number 89641-21-4) is a benzene derivative substituted with three boronic acid groups at the meta-position. Benzene-1,3,5-triyltriboronic acid reacts with various ligands to synthesise COFs. These reactions include dehydration reaction with boronic acids to form boroxine linkers, boronate esterification with diols to produce boronate ester linkers and Suzuki cross-coupling reaction with aryl halides. A conjugated COF, synthesised from benzene-1,3,5-triyltriboronic acid and dibromoanthraquinone, is used for sodium-ion battery cathodes. The resulting material delivers a high capacity of 200 mAh/g and rate performance of 105 mAh/g at 200 °C.

Benzene-1,3,5-triyltriboronic acid also reacts with copper sulfate for a 2D MOF material with well-defined supramolecular structures. The 2D MOF exhibits a conductivity of 0.087 S/cm.
