摘要
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。
he interaction of phenols and their potassium salts as electron donor with electron acceptor tetracyanoethylene (TCNE) led to the formation of the charge transfer(CT) complexes in CH3CN. The CT spectra were measured by visible or/and ultraviolet spectrometry and ionization potential of the donor was calculated by comparison method. The results showed that 4cyanophenol did not form CT complex with TCNE. Phenoxides were better donors than corresponding phenols. Linear relations were found between the hνCT of complexes of phenols with TCNE and Hammett substituent constant σ.
