Overview
Related Products

3,3'-Dihydroxy-[1,1'-biphenyl]-4,4'-dicarbaldehyde (CAS number 14969-32-5) contains two salicylaldehydes connected at the 4,4'-positions. 3,3'-Dihydroxy-[1,1'-biphenyl]-4,4'-dicarbaldehyde is commonly used to synthesise Schiff base COF with amine derivatives. Additionally, salen-COFs can be prepared by using ethylenediamine in the synthesis. Salen-COFs feature salen (salicylaldehyde and enthylenediamine) linkages within the COF networks, which provide tetradentate sites for coordinating with metal centres in various applications.

A COF based on 3,3'-dihydroxy-[1,1'-biphenyl]-4,4'-dicarbaldehyde and porphyrin is applied for electrocatalytic oxygen evolution reactions. This bimetallic two-dimensional COF exhibits remarkable turnover frequency value up to 26.19 s⁻¹ at an overpotential of 500 mV.
