Fig. 7. Photo-triggered ion transport by 1a (0.5 mol% relative to lipid) from POPC vesicles containing 489 mM NaCl, suspended in 489 mM NaNO3, and buffered with phosphate salts at pH 7.0. Chloride efflux from POPC vesicles monitored by a chloride-selective ISE. Colours indicate commencement of sample irradiation using 625 nM (0.9 W, red) or 455 nm (1.1 W, blue) LEDs. Black squares: vesicle exterior Cl– concentration; lines: linear fit.
