摘要
在非水溶剂（二甲基亚砜（ＤＭＳＯ）及Ｎ，Ｎ＿二甲基甲酰胺（ＤＭＦ））中的伏安曲线．呈现三对电流峰，表明存在三个可逆或准可逆酞菁配体的单电子转移过程，而在水溶液中则不呈现准可逆行为，且波形改变很大．此外，还比较了四磺酸基酞菁锌的水溶液在自然光和红光（６００～７００ｎｍ）照射下的循环伏安曲线，其氧化还原峰的数目和峰电位基本不变，但在红光照射下比自然光照射下的峰电流明显增大．
The voltammetry of Tetra_sulphonated phthalocyanine Zn(TSPcZn)in DMSO and DMF solution has been examined and compared with those obtained in aqueous solution.The results showed that three pairs of redox peaks were appear in non_aqueous solvents,exhibiting three quasi_reversible phthalocyanine ligand based one_electron transfers,while in aqueous solution did no quasi_reversible behaviour was observed. The photoelectrochemical effect of light on TSPcZn redox reactions were also discussed.
