Covalent Organic Frameworks (COFs) Quinquephenyl Ligand

A trigonal bridging ligand linker for covalent organic frameworks (COFs) in application of photocatalysts for hydrogen evolution reactions (HERs), hydrochloric acid and ammonia vapor sensing, and anticancer activity


Specifications | MSDS | Literature and Reviews


5''-(4'-Formyl-[1,1'-biphenyl]-4-yl)-[1,1':4',1'':3'',1''':4''',1''''-quinquephenyl]-4,4''''-dicarbaldehyde (TFBPB) has a trigonal structure with three 4-formyl-[1,1'-biphenyl] units attached to a central benzene ring at 1,3,5-positions.

With the combination of efficient light harvesting capability of a suitable band gap and catalytic sites, covalent organic framework TFBPB-TAT-COF with D-A type alternating units of TFBPB and 2,4,6-tris(4-aminophenyl)-1,3,5-triazine shows promise as an ideal photo absorber and photocatalyst for hydrogen revolution reactions (HERs). TFBPB-TAT-COF also shows excellent anticancer activity for human colorectal carcinoma HCT-116 cells.

Vinyl tetrazine-linked covalent organic frameworks TA-COF-2, obtained from Knoevenagel condensation reaction between 3,6-bis((E)-2-([1,1'-biphenyl]-4-yl)vinyl)-1,2,4,5-tetrazine and TFBPB, demonstrates high crystallinity and specific surface areas of 1114 m2 g−1 with favourable band gaps and position as photocatalyst in the arylboronic acids oxidation and light-induced coupling of benzylamines. TA-COF-2 also shows sensing capability with reversible colour changes upon exposure to HCl solution, HCl vapor, and NH3 vapor.
