摘要
利用光谱电化学方法来研究冠醚类化合物的文章尚未见报导.本文在测定用凝胶法合成的[Co(H_2O)(NCS)_2](18-C-6)的核磁共振谱和红外光谱的基础上,使用循环伏安法和薄层光谱电化学技术,在金微栅电极上测定了此配合物在乙腈溶剂中的第一步克式量电势(E^0′)和电子转移数(n),并推测了电还原反应机理.
The reduction of the title complex on a micro golden grid electrode using thin layercyclic voltammetry and spectrcelectrochemistry techniques was studied. The results showedthat the transfer number of the first step reduction of Co(Ⅱ) was 1, and E^0= -0.583V(vsSCE). A mechanisum was Proposed.
