Near perfect head-to-head selectivity on the supramolecular photocyclodimerisation of 2-anthracenecarboxylate with self-organised gemini surfactant bilayers

Abstract

Silicificated self-organised crystalline bilayers of gemini surfactants were used as reaction templates for the supramolecular regioselective [4+4] photocyclodimerisation of 2-anthracenecarboxylate in water. A near perfect head-to-head cyclodimer selectivity, up to 97% at room temperature, was achieved with accelerated rate.
