本文以八种取代酚及相应的取代酚钾作为电子给体，以四氰基乙烯（ＴＣＮＥ）作为电子受体，在乙腈溶液中用紫外可见分光光度法测定了取代酚及相应的取代酚钾与ＴＣＮＥ作用的电荷转移络合物的光谱，以其ＣＴ光谱用比较法计算了取代酚及相应的取代酚钾的电离势．结果表明，除４－氰基苯酚外，其余取代酚及取代酚钾均可与ＴＣＮＥ形成电荷转移络合物，取代酚钾比相应的取代酚有更好的给电子能力，取代酚的电子转移能与Ｈａｍｍｅｔ取代基常数有较好的线性相关关系
In this paper, eight kinds of substituted phenols and corresponding substituted potassium and potassium as electron donors, tetracyanoethylene (TCNE) as electron acceptor in acetonitrile solution was measured by UV-Vis spectrophotometry to replace the corresponding phenol and potassium The spectra of the charge-transfer complexes with TCNE were compared with those of substituted phenols by the comparison of their CT spectra. The results showed that except for 4-cyanophenol, all the substituted phenols and potassium substituted phenols could form charge-transfer complexes with TCNE. The substituted phenols were more electron-donating than the corresponding substituted phenols. The electron transfer of substituted phenols It has a good linear relationship with Hammet substituent constants
