摘要：本文测定八种2-(p-取代苯乙烯基)噻唑碘盐染料的电子光谱。研究其吸收光谱的λ_(max)与取代基常数σ之间的定量关系,以λ_(max)值对Δσ(σρ-σm)作图呈线性趋势。并发现这些染料吸收带的溶剂效应符合 Nicol 理论。
The electronic spectra of eight 2-(p-substituted styryl)thiazolium iodides have been determined.The quantitative relationship between the λ_(max) of the compounds and the Hammett constant has been studied.The λ_(max) values of absorption spectra were plotted against the Δσ(σ_p-σ_m)with a linear tendency.It was found that the solvent effects on the absorption bands of these dyes conformed with Nicol theory.
