摘要
合成了标题化合物,利用EA、1HNMR、IR表征了其结构;借助DSC、原位升温IR、13CNMR和分子荧光光谱法等研究了其热色性能。结果表明,温度变化引起的标题化合物的颜色变化,是由于异构体烯醇亚胺和酮胺式可逆性的互变导致的。
A novel Shiff base 2-N-（2-hydroxyl-naphthaldehyde）-imino-5-bromine-pyridine has been synthesized.The title compound was characterized by elemental analysis,1HNMR,and IR spectroscopy.The thermochromic properties were studied by DSC analysis,1HNMR,in-situ elevated temperature IR,13CNMR and fluorescence spectroscopy.The test results showed that the reversible thermochromism was resulted from the reversible tautomerism of enol-imine and keto-amine forms.
