Abstract: Two azo-porphyrins were synthesized by aromatic nitro-group reduction, diazotization and coupled reaction from tetra(nitrophenyl)porphyrin. They were characterized with 1H NMR, MS, IR and UV-visible spectra.Dual layer devices were prepared by using the azo-porphyrins as charge-generation layer separately, and their photoconductivities were measured and discussed. The experimental results showed that the photoconductivities of azo-porphyrins were improved compared to tetraphenylporphyrin (TPP). Their sensitivities are 1.8 and 28.8 lx•s respectively.

摘要: 以对硝基苯甲醛和吡咯为原料合成了对硝基苯基卟啉,再经硝基还原、重氮化和偶合反应合成了两种多偶氮连接的卟啉化合物,并用核磁、质谱、红外光谱及紫外-可见光谱对化合物进行了结构表征.分别以这些卟啉化合物为电荷产生材料制备了功能分离型双层光电导体,并对其光电导性能进行了研究.结果表明,偶氮卟啉的光敏性明显优于四苯基卟啉,其光敏性分别为1.8和28.8 lx•s.
