200–400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability and solvent–solute hydrogen-bonding interactions were analyzed by means of the linear solvation energy relationship concept proposed by Kamlet and Taft. The lipophilicities of the investigated hydantoins were estimated by calculation of their log P values. The quantitative relationship between the ratio
摘要合成了一系列5-取代的5-苯基乙内酰脲,并在不同极性的选定溶剂中于200-400 nm范围内记录了它们的紫外吸收光谱。借助Kamlet和Taft提出的线性溶剂化能量关系概念,分析了溶剂的偶极/极化性和溶剂-溶质氢键相互作用的影响。通过计算它们的log P值来估计所研究的乙内酰脲的亲脂性 。讨论了特定溶剂相互作用的贡献比与相应的亲脂性参数之间的定量关系。相关方程式与相应的ED 50组合值和不同的理化参数来生成新的方程式,以证明溶质-溶剂相互作用与结构-活性参数之间的合理关系。为了确定不同溶剂中吸收带的光谱分配,进行了量子化学计算。 图形概要
