英文摘要	合成了一种光降解的两亲性希夫碱染料,(E)-N-十八烷基-2-[2-(4-N,N-二甲基氨基苯基)胺烯基]吡啶碘化物（PN2）,考察了它的成膜性能,并成功地应用LB膜技术将其转移到石英基片或ITO电极上形成单层膜.对其光化学和光电化学性质的研究表明：它是一个具有二阶非线性光学性质(SHG)和光电响应性质(PEC)的可降解有机染料.化合物PN2单层LB膜的宏观二阶非线性系数为145.6pm·V－1.在含有0.1mmol·L－1氢醌的0.5mmol·L－1KCl电解质溶液中,无偏压时、500nm波长下,PN2-ITO电极的光电转化外量子产率为1.37％.; An amphiphilic azo-methine dye (E)-N-octadecyl-2- [2-(4- N, N-dimethyl aminophenyl) azomethinyl] pyridinium iodide (PN2), was synthesized. The dye molecule was successfully transferred onto quartz (or ITO slides) by Langmiur-Blodgett (LB) technique. The study on its photochemical and photoelectrochemical properties indicates that the azo-methine dye is a photodegradable compound. And second-harmonic generation (SHG) and photoelectric conversion (PEC) properties for this dye were observed. Its chi(zzz)((2)) is 145.6 pm . V-1, and its quantum yield of photocurrent generation is 1.37% in 0.5 mol . L-1 KCI solution containing 0.1 mmol . L-1 hydroquinone, degassed with N-2 and at zero bias voltage (vs SCE).; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000089651200006&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 2; 09; 787-791; 16
