摘　　要：以简单原料出发,通过Sonogashira偶联反应和三甲基硅基(TMS)的保护与脱保护,合成了一系列N,N-二苯基取代的芳炔化合物SC1～SC5.这类化合物是以N,N-二苯基为电子给体,羧基为电子受体,芳香炔体系为共轭桥的染料.将化合物SC5吸附到TiO2膜上制备成有机染料敏化太阳能电池,在AM 1.5,100 mW/cm2的模拟太阳光下,电池的光电转换效率(IPCE)值最大达到64%,而且在350～580 nm的范围内都可达到50%以上.电池的短路电流密度Jsc=8.0mW/cm2,开路电压Voc=0.75 V,填充因子为FF=0.70,总光电转换效率η=4.2%.A series of diphenylamino-substituted arylene-ethynylenes SC1-SC5 were synthesized by Sonogashira coupling reaction and protect-deprotect of trimethylsilyl （TMS） group. These compounds are dyes that substituted by diphenylamino group as electron donor, carboxyl as electron acceptor and arylene-ethynylene group as n-conjugated bridge. Target molecular SC5 was applied to nanocrystalline TiO2 dye-sensitized solar cells. For a typical device the maximal monochromatic incident photon-to-current conversion efficiency （IPCE） can reach 64% in the range of 350~580 nm, it can reach more than 50%, with a short-circuit photocurrent density （Jsc） 8.0 mA＊cm-2, an open-circuit photovotage （Voc） 0.75 V, and fill factor （FF） 0.70, which corresponds to an overall conversion efficiency （η） of 4.2%.
