A light-gated synthetic ion channel

Org Lett. 2008 Sep 4;10(17):3693-6. doi: 10.1021/ol8013045. Epub 2008 Jul 26.

Abstract

A gated synthetic ion channel with beta-cyclodextrin as the pore and azobenzene as the gate is reported. Irradiation converts a tethered trans-azobenzene to cis-azobenzene which likely transforms the channel from a self-inclusion complex to a dissociated structure. This transformation results in an increase in anion transport and a decrease in cation transport across a phospholipid vesicle membrane.
