4,4'-(2,2-Diphenylethene-1,1-diyl)dibenzaldehyde (CAS 1601465-06-8) from Ossila is a dialdehyde building block based on a tetraphenylethylene core, supplied as an off-white powder with >98% purity. Its core has four benzene rings joined through an ethene unit, giving the molecule an extended conjugated system, while the two aldehyde groups provide reactive sites for condensation and coupling chemistry.
The compound is used as a ligand for covalent organic frameworks (COFs). Reacting it with its amine derivatives through imine linkages yields a one-dimensional COF with good crystallinity, high surface area and excellent chemical stability. In the electrocatalytic oxygen reduction reaction, this 1D COF has shown 85.8 % selectivity towards H2O2 and a turnover frequency (TOF) of 0.051 s−1 at 0.2 V.
Researchers working on luminescent materials have also combined it with benzylamine via reductive amination to prepare aggregation-induced emission (AIE) molecules.
