Two novel N-substituted anchoring porphyrins (ZnPAtz and ZnPAim) have been devised and synthesized. Moreover, these two anchoring porphyrins were linked to the TiO semiconductor through carboxyl groups and then a zinc porphyrin ZnP was bound to the anchoring porphyrin using a zinc-to-ligand axial coordination approach. The different performances of these assemblies were compared with single anchoring porphyrin devices ZnPAtz and ZnPAim. The photoelectric conversion efficiency of the new supramolecular solar cells sensitized by ZnP-ZnPAx (x=tz, im) has been improved. The ZnP-ZnPAtz-based DSSCs provided the highest photovoltaic efficiency (1.86%). Fundamental studies showed that incorporation of these assemblies promote light-harvesting efficiency.
已经设计并合成了两种新型的N-取代锚定卟啉（ZnPAtz和ZnPAim）。此外，这两种锚定卟啉通过羧基与TiO半导体相连，然后采用锌与配体轴向配位的方法将锌卟啉ZnP与锚定卟啉结合。将这些组装体的不同性能与单锚定卟啉器件ZnPAtz和ZnPAim进行了比较。由ZnP-ZnPAx（x = tz，im）敏化的新型超分子太阳能电池的光电转换效率得到了提高。基于ZnP-ZnPAtz的染料敏化太阳能电池提供了最高的光伏效率（1.86%）。基础研究表明，这些组装体的加入提高了光捕获效率。
