以N，N-二甲基苯胺为给体基团，通过一锅C-H活化法合成了3种新型3，4-乙撑二氧噻吩（EDOT）染料的前体。我们已经扩展了这种方法，以提供一个方便的一锅路线染色EDOT-Ph。新染料的电化学和光学性质已与IV和EQE数据1厘米2染料敏化太阳能电池（DSSC）使用这些染料制备的设备。器械数据显示，染料性能受到所用鹅去氧胆酸（CDCA）共吸附剂量的强烈影响。与N719和D205对照细胞（η = 6.0%和η = 5.8%）相比，在10 mM CDCA下EDOT-Ph（η = 4.0%）的性能最佳。
Precursors to three new 3,4-ethylenedioxythiophene (EDOT) incorportaing dyes have been synthesised via a one-pot C–H activation route using N,N-dimethylaniline as a donor group. We have extended this methodology to provide a convenient one-pot route to dye EDOT-Ph. The electrochemical and optical properties of the new dyes have been correlated with IV and EQE data for 1 cm2 dye-sensitized solar cell (DSSC) devices prepared using these dyes. The device data show that dye performance is strongly affected by the amount of chenodeoxycholic acid (CDCA) co-sorbent used. The best performance is for EDOT-Ph (η = 4.0%) at 10 mM CDCA compared to (η = 6.0% and η = 5.8%) for N719 and D205 control cells.
