| 摘 要： | 在苄叉丙二腈衍生物系列中,N,N-二烷基氨基苄叉丙二腈及其类似化合物是研究和应用较多的一类。它们曾作为分子探针应用于高分子微环境特性和高分子聚合过程的研究。作为一种分子内的电荷转移络合物,它们在不同溶剂中的光谱行为也进行过研究,从而为进一步的开拓应用提供了重要依据。和前者相比,对-羟基苄叉丙二腈无论在基础研究或实际应用上都显得比较薄弱。正因如此,本工作合成了该化合物并对它进行了初步研

| Abstract: | The absorption spectra of 4-hydroxybenzylidene malononitrile in different solvent systems have been studied in this work. It was found that this compound has a proton equilibrium under the different pH condition that results in a variation of absorption spectra observed. Thereby, the title compound is expected to be used as a new acidic indicator in nonaqueous media. |
