已经设计并合成了包含两个与噻吩单元连接的D-π-A分支的有机染料,以用于高效的染料敏化太阳能电池(DSSC)。与单一D-π-A类似物染料的棒状相比,双重D-π-A支化染料的十字形状有利于减少分子间的相互作用并阻碍电荷重组。受控强度调制的光电压光谱显示,双D-π-A染料基DSSC的电子寿命比相应的单D-π-A染料基DSSC的电子寿命长14倍。将两个D-π-A分支与噻吩单元链接在一起,可使开路光电压增加100 mV,短路光电流增加4.10 mA cm –2。结果,功率转换效率提高了约2倍。这项工作为设计具有高抑制电荷复合能力的敏化剂向高性能DSSC提供了一条新途径。

provided 40–72% yields of 2,5-disubstituted 3-(triisopropylsilyl)thiophenes and up to 50% yield of 2,5-disubstitutedthiophenes. Sulfur heterocyclization and 1,3-migration of silicon have been realized in the reactions of a range of 1,3-diynes with sodium triisopropylsilanethiolate in N,N-dimethylformamide. These provided 40–72% yields of 2,5-disubstituted 3-(triisopropylsilyl)thiophenes and up to 50% yield

A versatile synthetic route involving the use of organotin compounds has been applied for the preparation of functionalized oligothiophenes. Substituted bithiophenes have been synthesized via the coupling reaction of 2-bromothiophenes with 3-trimethylstannylthiophene. The latter reagent couples with bromoaromatics, bromoheteroaromatics and 2,5-dibromothiophenes to give the corresponding 3-arylthiophenes, 3-heteroarylthiophenes and terthiophenes, respectively. 2-Trimethylstannylthiophene couples with 2,5-dibromo-3-arylthiophenes to give 3-aryl-alpha-terthiophenes.The structures of the new compounds were confirmed by elemental analysis, mass spectrometry, H-1- and C-13- NMR spectral data.
