摘要
采用微电极电化学与薄层光谱电化学方法,研究了4-特丁基锰酞菁(TbPcMn)在非水溶剂中的电化学行为.结果表明,在二氯乙烷和四氢味喃溶剂中,得到的氧化和还原过程分别对应于Mn(Ⅲ)/Pc环阳离子自由基、Mn(Ⅲ)/Mn(Ⅱ)、Mn(Ⅱ)/Mn(I)以及Mn(I)/Pc环阴离子自由基的生成步骤.轴向配位效应考察表明,阴离子与锰金属中心的键合能力的顺序为:Cl^->I^->ClO_4^->BF_4^-.
The micro-electrochemical and thin-layer spectroelectrochemical behavior of tetra (t-butylphenoxy)-phthalocyanine manganese (Ⅲ) (TbPcMn) in nonaqous media was reported. Oneoxidation step of Mn(Ⅲ)/radical cation and three reduction steps correspond to the Mn(Ⅲ)/Mn(Ⅱ),Mn(Ⅱ)/Mn(Ⅰ), and Mn(Ⅰ)/radical anion were identified in tetrahydrofuran and C2H4Cl2 solutions.The bonding capability of different axial anion ligands was estimated as Cl-> I->ClO4->BF4-.
