A novel amphiphilic chromoionophore, N-[4-(2,3,6,7,8,9,11,12-octahydro-5H-1,4,10,13,7-benzotetraoxaazacyclopentadecin-7-yl)butyl]-4-2-[4-(N-methyl-N-hexadecylamino)phenyl]ethenyl}quinolinium bromide (Crown D), containing a DâÏâA styryl dye and an aza-15-crown-5 ether group was synthesized, and successfully transferred onto an indiumâtin oxide (ITO) electrode by the LangmuirâBlodgett technique. The effect of different metal cationic subphases on the ÏâA isotherm of Crown D was investigated. The photoelectric conversion properties of the chromoionophore LB monolayer films were studied. The results show that the photocurrent generation properties of the film strongly depend on the radius of the metal ions coordinated with the aza-15-crown-5 ring of the dye.
一种新型两亲性发色团--N-[4-(2,3,6,7,8,9,11,12-八氢-5H-1,4,10,13,7-苯并四氧杂氮杂环十五烷-7-基)丁基]-4-2-[4-(N-甲基-N-十六烷基氨基)苯基]乙烯基}溴化喹啉(Crown D)、合成了含有 DÏâA苯乙烯基染料和氮杂-15-冠醚-5 基团的皇冠 D,并利用 LangmuirâBlodgett 技术成功地将其转移到了氧化铟锡(ITO)电极上。研究了不同金属阳离子子相对皇冠 D ÏâA 等温线的影响。研究了发色团枸橼酸单层膜的光电转换特性。结果表明,薄膜的光电流产生特性在很大程度上取决于与染料的氮杂-15-冠-5 环配位的金属离子的半径。
