| 摘 要： | 以2,4-二硝基苯肼与取代苯甲醛为原料,通过室温固相反应合成了6种席夫碱衍生物,用元素分析、核磁共振等方法对产物进行了表征,并利用DSC技术对其变色过程进行了研究。用密度泛函理论的B3LYP方法对产物的分子结构进行优化,从理论上探讨了他们的变色机理。研究表明,此类席夫碱衍生物作为热致变色材料具有变色敏锐、颜色对比明显、可逆性好以及变色温度高等特点,是一类具有良好应用前景的可逆热致变色材料。

| Abstract: | In this paper,six schiff bases were prepared by solid state reaction of 2,4-dinitrophenylhydrazine with benzaldehyde at room temperature.Element analysis and H1NMR confirmed the structure of the product and the color change process were studied by DSC spectra.Molecular structure of the product was optimized by B3LYP method of DFT theory,and then the thermochromic mechanism was discussed.The research results show that the thermochromism materials have the advantages such as sharp swift color change speed,obvious color contrast,good reversibility and high color change temperature.In conclusion,the materials have good applied future. |
