4',4''',4'''''-(1,3,5-triazine-2,4,6-triyl)tris([1,1'-biphenyl]-4-carbaldehyde) (TFBPTz) is triangularly shaped with three 4-formylbiphenyl units sitting on a central triazine core.

Porous crystalline bipyridine-based Bpy-COF, constructed from Schiff base condensation of 4',4''',4'''''-(1,3,5-triazine-2,4,6-triyl)tris([1,1'-biphenyl]-4-carbaldehyde) and 5,5'-diamino-2,2'-bipyridine, shows great BET surface area of 1864 m2 g−1 with uniform mesopore  size of 4.0 nm. With retained ordered porous structure, copper loaded Cu(I)-Bpy-COF heterogeneous catalyst demonstrates high conversion rate of cycloaddition reactions within a short time of 40 min at 25 °C in water medium. POP-2, a COF with sp2-C linkage derived from 4',4''',4'''''-(1,3,5-triazine-2,4,6-triyl)tris([1,1'-biphenyl]-4-carbaldehyde) shows a dual response of colour and fluorescence under acidic conditions. It exhibits a red shift of nearly 100 nm in aqueous hydrochloric acid at a concentration of 1 M.

Ionic vinylene-linked 2D covalent organic framework TFBPTz-ETMP-COF, obtained by a quaternization-promoted Knoevenagel condensation between N-ethyl-2,4,6-trimethylpyridinium halide and 4',4''',4'''''-(1,3,5-triazine-2,4,6-triyl)tris(([1,1'-biphenyl]-4-carbaldehyde)), shows  high crystallinity and BET surface areas of 1343 m2 g−1. The positively charged COF can be uniformly composited with linear polyethylene oxide and lithium salt, displaying ionic conductivity as high as 2.72×10−3 S cm−1.

Highly crystalline, π-conjugated, and hydrophilic ionic covalent organic frameworks ZVCOF-2, a COF obtained from N-(3-sulfopropyl)-2,4,6-(trimethyl)pyridinium, inner salt (PSTMP) and TFBPTz with a green hydrothermal approach, shows an ultrahigh sacrificial photocatalytic hydrogen evolution rate of 2052 μmol h–1 under visible light irradiation with an apparent quantum yield up to 47.1% at 420 nm.
