New benzo[]quinolin-10-ol derivatives with one or two 2-cyanoacrylic acid units were synthesized with a good yield in a one-step condensation reaction. Chemical structure and purity were confirmed using NMR spectroscopy and elemental analysis, respectively. The investigation of their thermal, electrochemical and optical properties was carried out based on differential scanning calorimetry, cyclic voltammetry, electronic absorption and photoluminescence measurements. The analysis of the optical, electrochemical and properties was supported by density functional theory studies. The synthesized molecules were applied in dye-sensitized solar cells as sensitizers and co-sensitizers with commercial N719. The thickness and surface morphology of prepared photoanodes was studied using optical, scanning electron and atomic force microscopes. Due to the utilization of benzo[h]quinolin-10-ol derivatives as co-sensitizers, the better photovoltaic performance of fabricated devices compared to a reference cell based on a neat N719 was demonstrated. Additionally, the effect of co-adsorbent chemical structure (cholic acid, deoxycholic acid and chenodeoxycholic acid) on DSSC efficiency was explained based on the density functional theory.
通过一步缩合反应以良好的产率合成了带有一个或两个2-氰基丙烯酸单元的新型苯并[h]喹啉-10-醇衍生物。分别使用核磁共振光谱和元素分析确认了化学结构和纯度。基于差示扫描量热法、循环伏安法、电子吸收和光致发光测量对其热、电化学和光学性质进行了研究。密度泛函理论研究为光学、电化学和性质分析提供了支持。将合成的分子作为敏化剂和与商业N719的共敏化剂应用于染料敏化太阳能电池中。使用光学显微镜、扫描电子显微镜和原子力显微镜研究了制备的光阳极的厚度和表面形态。由于使用苯并[h]喹啉-10-醇衍生物作为共敏化剂，与基于纯N719的参比电池相比，所制备器件展现出了更好的光伏性能。此外，基于密度泛函理论解释了共吸附剂化学结构（胆酸、脱氧胆酸和鹅去氧胆酸）对染料敏化太阳能电池效率的影响。
