摘要： 将N,N′-二-（9,9′-二己基芴）胺作为电子供体引入具有推拉电子结构的卟啉染料中，设计合成了2个新的染料敏化太阳能电池(DSSCs)敏化剂WP-1和WP-2。 利用核磁共振氢谱和高分辨质谱对染料结构进行了表征。 测试了染料的紫外可见吸收光谱。 将其应用于染料敏化太阳能电池中，在模拟太阳光(100×10-3 W/cm2)照射下，染料WP-1和WP-2敏化电池的能量转换效率分别达到了4.01%和7.07%。 WP-2敏化的电池封装后经自然光照射500 h后，光电效率仍能维持在初始效率的98%以上。 说明N,N′-二-（9,9′-二己基芴）胺作为电子供体，很适合推拉电子结构的卟啉染料。 不仅丰富了用于卟啉染料的电子供体的种类，也为进一步将二芴胺衍生物引入到卟啉染料中的研究奠定了基础。

Abstract: Two new electron donate-withdraw structured porphyrin dyes(WP-1 and WP-2) with bis(9,9-dihexyl-9H-fluoren-2-yl)amine as an electron donor were designed and synthesized. The structures of the two dyes were characterized by proton nuclear magnetic resonance and high resolution mass spectra technologies. The UV-visible absorption spectra of the two dyes were tested. Dye-sensitized solar cells(DSSCs) using the two dyes gave high power conversion efficiencies of 4.01% and 7.07% under 100×10-3 W/cm2 illumination, respectively. The sealed DSSCs sensitized with dye WP-2 could keep more than 98% of the initial efficiency under natural sunlight irradiation for 500 h, which illustrated that the bis(9,9-dihexyl-9H-fluoren-2-yl)amine is suitable in the electron donate-withdraw structured porphyrin dyes as an electron donor. This not only enriched the types of electron donors, but also built the foundation for further research on bisfluorenamine derivative as electron donor in porphyrin dyes.

Key words: porphyrin dye, dye-sensitized solar cells, electron donor, bis(dihexyl-9H-fluoren-yl)amine
