hydrophobic moiety attached on a carboxylic or phosphoric acid terminal anchoring group, which chemisorbs on the semiconductor surface. In this work, the synthesis of a new family of 8-quinolinol derivatives bearing alkyl chains of variable length at the 5-position is described and their comparative efficiency as effective bidentate co-adsorbents in DSCs is evaluated. The key step towards their straightforward
在染料敏化太阳能电池 (DSC) 中使用共吸附剂可提高这些设备的功率转换效率和长期稳定性。共吸附剂通常由附着在羧基或磷酸末端锚定基团上的疏水部分组成,该基团化学吸附在半导体表面上。在这项工作中,描述了在 5 位带有可变长度烷基链的 8-羟基喹啉衍生物的新家族的合成,并评估了它们作为 DSC 中有效双齿共吸附剂的比较效率。实现其直接模块化合成的关键步骤是 5-氯-8-甲氧基喹啉和烷基三氟硼酸盐之间的 Suzuki 偶联。与烷基羧酸类似物相比,新化合物作为共吸附剂在细胞效率方面表现出更好的性能,
