4,4''-p-Terphenyldicarboxaldehyde CAS 62940-38-9

Covalent Organic Frameworks (COFs) Terphenyl Ligand

A formyl functional ligand linker for COFs in application of highly efficient electrochemiluminescence, photocatalyst, oxygen reduction reactions, iodine adsorption and water pollutant detection and removal

Overview
Related Products

4,4''-p-Terphenyldicarboxaldehyde (TPDA), CAS number 62940-38-9, has a linear terphenyl structure with one aldehyde on each end of the phenyl rings.

Two-dimensional COF, TCPP-TPDA-COF, with porphyrin active sites and natural π-electron network of terphenyl structure as the charge transport passage, facilitated the photo-induced aqueous oxygen-tolerant PET-RAFT polymerization under multi-wavelength visible light.

Constructed by Schiff base condensation reaction between 5,10,15,20-tetrakis(4-aminophenyl)-21H,23H-porphyrin (Tph) and 4,4''-p-Terphenyldicarboxaldehyde, covalent organic framework Tph-TPDA-COF showed excellent photocatalytic activity.
