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

Overview
Related Products

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.
