Specifications | MSDS | Literature and Reviews


4,4'-(2,2-Diphenylethene-1,1-diyl)dibenzaldehyde (CAS number 1601465-06-8), is a tetraphenylethylene-based ligand with two aldehyde groups. The tetraphenylethylene core consists of four benzene ring connected by a ethene, making 4,4'-(2,2-diphenylethene-1,1-diyl)dibenzaldehyde highly conjugated. Therefore, 4,4'-(2,2-diphenylethene-1,1-diyl)dibenzaldehyde has been employed in combination with benzylamine to synthesise aggregation-induced emission (AIE) molecules through reductive amination.

A one-dimensional COF (1D-COFs) can be prepared from 4,4'-(2,2-diphenylethene-1,1-diyl)dibenzaldehyde and its amine derivatives with imine linkages. The resulting 1D COF displays good crystallinity, high surface areas and excellent chemical stability for electrocatalytic oxygen reduction reaction. It exhibits a high H2O2 selectivity of 85.8 % in the oxygen reduction reaction, with a catalytic turnover frequency (TOF) value of 0.051 s−1 at 0.2 V.
