Triangular 5'-(4-Formylphenyl)-2',4',6'-trimethyl-[1,1':3',1''-terphenyl]-4,4''-dicarbaldehyde (TMTFPB), CAS number 2195343-70-3, has three methyl and three formylphenyl groups sitting on a benzene ring, alternating methyl and formylphenyl groups.

[(TTFB)₄(ETTA)₃]imine, termed COF-790, prepared from building blocks of 1,3,5-trimethyl-2,4,6-tris(4-formylphenyl)benzene (triangle) and 1,1,2,2-tetrakis(4-aminophenyl)ethene (square) into the fjh topology, exhibited permanent porosity and a high Brunauer–Emmett–Teller (BET) surface area of 2650 m² g^–1.

F-COF-2, also derived from 5’-(4-formylphenyl)-2’, 4’, 6’-trimethyl-[1, 1’: 3’, 1’-terphenyl]-4,4’’-dicarbaldehyde and 2,4,6-tristyryl s-triazine as the building block monomers, displayed combined skeleton and spatial rigidification endowed excellent fluorescence emission. F-COF-2 showed highly sensitive and selective nitrofurantoin (NFT) detection with a K_SV value of 9.12 × 10⁵ M^–1, and limit of detection of 3.35 ppb.
