中文摘要：

利用热凝聚法合成四苯并卟啉锌的经典反应,加入过量的丁二酸钠代替原反应物乙酸钠,控制合成了中位-四（羧基亚甲基）苯并卟啉锌.由于羧基的引入,使卟啉分子能够锚定在二氧化钛表面.为转移卟啉激发态电子到二氧化钛的导带提供了通道,并改善了其在二氧化钛表面的分散性,从而使苯并卟啉锌敏化太阳能电池的效率明显提高.

英文摘要：

Based on the classic synthesis of zinc tetrabenzoporphyrin by the thermal condensation method, zinc meso-tetra（carboxylmethylene） benzoporphyrin are successfully synthesized using an excessive sodium suceinate instead of the original sodium acetate. Due to the introduction of carboxyl groups, porphyrin can be firmly anchored to the surface of the semiconductor of titanium dioxide. They offer the channels for electrons transferring from excited state of the porphyrin to the conduction band of titanium dioxide and improve the dispersion of porphyrin on titanium dio- xide. The efficiency of zinc meso-tetra（carboxylmethylene）benzoporphyrin in dye-sensitized solar cells is markedly increased.
