We have developed a one-pot, four-component Suzuki–Miyaura coupling for the synthesis of thiophene-based donor–π-bridge–acceptor (D–π–A) dyes for dye-sensitized solar cells. Two D–π–A dyes, 19 and 20, retaining 3,4-ethylenedioxythiophene (EDOT) beside a cyanoacrylic acid moiety, and one D–π–A dye 21 without EDOT (reference compound) were rapidly synthesized in accordance with the developed procedure
我们已经开发了一种一锅四组分的Suzuki-Miyaura偶联剂,用于合成用于染料敏化太阳能电池的噻吩基供体-π-桥-受体(D-π-A)染料。根据开发,快速合成了两种D-π-A染料19和20,它们在氰基丙烯酸部分旁边保留了3,4-乙撑二氧噻吩(EDOT),和一种不带EDOT的D-π-A染料21(参考化合物)。程序。的吸收光谱和合成染料的电化学特性,和使用合成的染料制备的太阳能电池的光伏性能的测量19 - 21,显示,只保留一个EDOT一氰基丙烯酸部分旁边的染料会发挥较高Ĵsc。
