Photodimerisation of a styrylpyrazine amphiphile suppresses the release of glucose entrapped in its mixed vesicle with DPPC

Photolysis of a styrylpyrazine amphiphile in the bilayer of a vesicle made from its mixture with DPPC, with irradiation above 300 nm, effectively suppressed the release of glucose entrapped in the vesicle, while the stilbene analogue induced a sudden perturbation to release the glucose under the same conditions.
