A spirobenzopyran derivative (1′-hexadecy1-3′,3′-dimethy1-6-nitrospiro[2H-1-benzopyran-2,2′-indolinen]) was immobilized into poly(vinyl chloride) membrane in order to study the photo-response of the membrane potential. UV light irradiation induced membrane potential changes of more than 100 mV with a response time of ca. 1 min. The photoinduced potential changes were larger in the lower ionic concentration region. Photo-response was also observed when no concentration gradient of electrolyte between the two solutions existed; this was explained based on the formation of asymmetric membrane under UV light irradiation. Photo-response of the membrane potential was enhanced in the slightly acidic region, suggesting an important role of the protonated form of opened spirobenzopyran in determining the membrane potential.
