英文摘要	合成了具有不同共轭链长度的吡啶盐类及喹啉盐类半菁染料(E)-N-(4-磺酸丁基)-4-犤2-(4-N,N-二甲基氨基苯基)乙烯基犦吡啶盐(P1)、(E)-N-(4-磺酸丁基)-4-犤2-(4-N,N-二甲基氨基苯基)丁二烯基犦吡啶盐(P2)、(E)-N-(4-磺酸丁基)-4-犤2-(4-N,N-二甲基氨基苯基)乙烯基犦喹啉盐(Q1)以及(E)-N-(4-磺酸丁基)-4-犤2-(4-N,N-二甲基氨基苯基)丁二烯基犦喹啉盐(Q2).研究了它们的光物理性质,并将它们用作TiO2纳米晶电极的光敏化剂引入光电化学电池.与含有乙烯基共轭桥的染料P1和Q1相比,含有丁二烯基共轭桥的染料P2和Q2在甲醇和氯...; Four hemicyanine derivatives, (E)-N-(4-sulfobutyl)-4-[2-(4-N, N-dimethylamino-phenyl)ethenyl] pyridinium(PI), (E)-N-(4-sulfobutyl)-4-[2-(4-N, N-dimethylaminophenyl)-1,3-butenyl]pyridinium(P2), (E) -N-(4-sulfobutyl)-4-[2-(4-N, N-dimethylaminophenyl)ethenyl] quinolinium(Q1) and (E)-N-(4-sulfobutyl)-4-[2-(4-N, N-dimethylaminophenyl)-1,3-butenyl]quinolinium(Q2), with different conjugated bridge and acceptor groups, have been synthesized and characterized with regard to their photophysical and photoelectrochemical properties. Experiments show that with extended pi-conjugation bridge, the lambda(max) of P2 and Q2 both red shifted and their absorption spectra broadened, which is advantageous for photoelectric conversion. Photoelectric properties of the four dye sensitized TiO2 electrodes were investigated in standard two-electrode system, and the data obtained show that Q1 has the best photo-to-electron conversion among the four dyes.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000184412100014&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 4; 07; 635-640; 19
