英文摘要	Two amphiphilic nitrobenzene dyes 3-(CH3O)-4-(C18H37O)-C6H3-CH=N-NH-C6H4-NO2 a (dye(1)) and 4-(C18H37O)-C6H4-CH=N-NH-C6H4-NO2 (dye(2)) were synthesized and deposited on semiconducting transparent ITO electrodes by a Langmuir-Blodgett (LB) technique. The photocurrent generations have been studied in a conventional photoelectrochemical cell. Action spectra of the photocurrent generation are coincident with the absorption of the LB film-modified electrodes, indicating that the dye aggregates in the LB film are responsible for the photocurrent. Some factors which may affect the observed photocurrent, such as existence of O-2, concentration of MV2+ (methyl viologen) and H(2)Q (hydroquinone), pH values, and the bias voltage, have been investigated. On the basis of exp photocurrent generation under different conditions are proposed.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000074769100010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Multidisciplinary; Chemistry, Physical; Materials Science, Multidisciplinary; SCI(E); 21; ARTICLE; 14; 3783-3787; 14
