合成了两种吲哚类有机染料，并对其进行了表征。三苯胺或咔唑基团与吲哚基团键合，作为潜在的电子给体，可以调节染料的HOMO和LUMO能级，而另一个三苯胺或咔唑基团与氮原子上的吡咯环键合，有望在一定程度上抑制染料在固态下的聚集。这两种染料被用作染料敏化太阳能电池中的染料敏化剂，并表现出有效的光子-电子转换特性。
Two indole-based organic dyes were conveniently prepared and well characterized. The triphenylamine or carbazole moieties were bonded to the indole group acting as a potential electron donor, which can tune the HOMO and LUMO levels of the resultant dye, and another triphenylamine or carbazole group was linked to the pyrrole ring on the nitrogen atom, which was expected to suppress the aggregation of the dye in the solid state to some degree. These two dyes were utilized as dye sensitizers in dye-sensitized solar cells and demonstrated efficient photon-to-electron conversion properties.
