四硝基酞菁锌配合物的光谱电化学性质

Spectroelectrochemistry of Zn( Ⅱ) Tetranitrophthalocyanine Complex

带有各种取代基的酞菁配合物虽已有研究,但有关硝基酞菁锌配合物在溶液中的氧化还原产物研究尚未见报道.本文用薄层光谱电化学技术对该配合物的电解产物进行了研究. 1 实验部分 HDP-1型恒电位仪;F-78型脉冲极谱仪;UV-240型紫外可见分光光度计.四硝基酞菁锌(ZnTNPc)按文献合成和提纯.电化学实验在氮气中于三电极电解池中进行,工作电极(0.001cm^2)、辅助电极均为铂丝,银丝为参比电极,二茂铁作内参比物.支持电解质为0.1mol/L TBAP,ZnTNPc浓度为1.0×10^(-5)mol/L.光谱电化学实验方法见文献,电解液为0.3mol/L TBAP和1.0×10^(-4)mol/L ZnTNPc.

The electrochemistry of the title complex was studied in DMF. With the use of an optically transparent electrode, the electronic spectra of five different oxidation states were reported. The redox mechanism and the species on the electrode were also discussed.
