4',4''',4'''''-(1,3,5-triazine-2,4,6-triyl)tris([1,1'-biphenyl]-4-amine) (TABPT) is a trigonal triazine derivative with [1,1'-biphenyl]-4-amine] groups at 2,4,6-positions.

COF C6-TRZ-TFP, prepared by solvothermal Schiff base polycondensation of 2-hydroxybenzene-1,3,5-tricarbaldehyde (TFP) and 4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)tris[(1,1′-biphenyl)-4-amine], showed excellent hydrogen evolution reaction activity in electrochemical water splitting, with a very low overpotential of 200 mV and specific activity of 0.2831 mA cm−2 together with high retention of catalytic activity after a long duration of electrocatalysis in 0.5 M aqueous H2SO4.

COF-4, obtained from the condensation of tripodal amine 4,4′,4″-(1,3,5-triazine-2,4,6-triyl)tris(([1,1′-biphenyl]-4-amine)) and 2,4,6-triformylresorcinol with very suitable band gaps of 1.95 eV, shows a high-efficiency photo-biocatalytic activity for coenzyme nicotinamide adenine dinucleotide NADH photo regeneration and enhanced visible light-driven formic acid production at a rate of 226.3 μmol g–1 in 90 min.

Readily polycondensation cross-coupling reactions  to form COF networks

Polycondensation of benzotrithiophene (BTT) and (1,3,5-triazine-2,4,6-triyl)tris([1,1´-biphenyl]-4-amine) affords crystalline, and porous imine-linked COF with a BET surface area of 1200 m2 g−1. Room temperature in-plane electrical conductivity of up to 10−4 S m−1 is measured for the COF film.

π-electron-extended triazine-based covalent organic framework (TFP-TPTPh COF) with excellent crystallinity and a high surface area of 724 m2 g−1, demonstrates remarkable photocatalytic degradation rate of RhB dye molecules with an efficiency of 97.02% under ultraviolet–visible light irradiation. Also, TFP-TPTPh COF shows an excellent photocatalytic capacity for reducing water to generate H2 with a hydrogen evolution rate (HER) of 2712 μmol g−1 h−1.
