| Abstract: | Photoirradiation induced potential changes of 10–20 mV across the poly(vinyl chloride) membranes doped with a photosensitive lipophilic crown ether, p-3,4-(1,4,7,10,13-pentaoxatridecane-1,13-diyl)phenylazo]hexadecyloxybenzene was studied. The photoresponse of the membrane was highly improved, presumably due to the lipophilic nature of the crown ether. The photoresponse was explained in terms of the charge density change on the membrane surface. The electric double layer theory was applied to estimate the values of the photoinduced change of the charge density. |
