摘　　要：本文采用了优化路径分别合成出了四羟基苯基卟啉(THPP)和及其衍生物四羟基苯基锰卟啉(THPP-Mn)两种化合物,并对它们的结构与性能进行了表征。THPP和THPP-Mn在丙酮溶剂中的紫外可见光谱表明,相对于THPP,THPP-Mn的紫外可见光谱中的Soret带发生红移,吸收峰从419 nm移到476 nm,THPP-Mn的Q带吸收峰的个数减小,这是因为卟啉生成配合物后对称性增强而使吸收峰数目减少的缘故。电化学测试结果表明,四羟基苯基锰卟啉有一对明显的氧化还原峰,具有较好的氧化还原可逆性,并且随着扫描速率从10 mV/s增加到200 mV/s,其氧化峰从1.32 V逐渐增加到1.53 V,还原峰从0.94 V减少到0.74 V。因此,四羟基苯基锰卟啉具有较好的电化学性能,在储能材料领域具有很好的应用前景。Meso-tetra(p-hydroxyphenyl)porphine(THPP)and meso-tetra(p-hydroxyphenyl)manganese porphyrin(THPP-Mn)were synthesized by the route of optimization.The UV-vis spectra of THPP in the acetone exhibited a Soret band(419 nm).The UV-vis spectra of THPP-PA-Mn in the acetone exhibited a Soret band(476 nm)which are similar to that of other Mn(II)-porphyrins materials.So the formation of THPP-Mn was verified by monitoring the red shift of the Soret band from 419 to 476 nm.Cyclic voltammetry measurements showed that THPP-Mn exhibited a good reversible redox property since the Mn(II)-porphyrins moieties have electron conjugated bonds.In a word,THPP-Mn with a good reversible redox property was reported as a promising material for energy storage.
