AI Technical Summary
Existing photocatalytic olefin isomerization technologies suffer from problems such as dependence on precious metals, high cost, difficulty in recycling, poor stability, narrow light response, energy level mismatch, low efficiency, poor selectivity, and weak substrate universality.
The anthracene-based DA-type heptaazine polymer photocatalyst is formed by the Schiff base polycondensation reaction of 1,4-dianthraaldehyde and melamine. A conjugated polymer structure with anthracene units as donors and heptaazine units as acceptors is constructed and connected by alternating imine bonds. Combined with the segmented heating solvothermal Schiff base polycondensation method, a continuous electronic push-pull system is formed.
It achieves efficient, visible light-responsive, precisely matched energy level, and highly selective olefin isomerization with excellent product yield. The catalyst is recyclable, applicable to a variety of olefin substrates, meets the requirements of green chemistry, and reduces preparation and application costs.
