New β-amino-substituted porphyrin derivatives bearing carboxy groups were synthesized and their performance as sensitizers in dye-sensitized solar cells (DSSC) was evaluated. The new compounds were obtained in good yields (63-74%) through nucleophilic aromatic substitution reactions with 3-sulfanyl- and 4-sulfanylbenzoic acids. Although the electrochemical studies indicated suitable HOMO and LUMO energy levels for use in DSSC, the devices fabricated with these compounds revealed a low power conversion efficiency (PCE) that is primarily due to the low open-circuit voltage (V) and short-circuit current density (J) values.
新型含羧基的β-氨基取代卟啉衍生物的合成及其在染料敏化太阳能电池（DSSC）中的敏化性能进行了评价。通过 3-巯基和 4-巯基苯甲酸的亲核芳香取代反应，以良好的产率（63-74%）得到了这些新化合物。尽管电化学研究表明它们的 HOMO 和 LUMO 能级适合用于 DSSC，但用这些化合物制备的器件显示出低的功率转换效率（PCE），这主要是由于开路电压（V）和短路电流密度（J）值较低。
