水杨醛缩甲基氨基硫脲的合成及其光化学性质研究

Studies on the Synthesis,Structures and Photochemical Properties of Salicylaldehyde N(4)-Methyl-Thiosemicarbazone

合成了一个新的光致变色化合物水杨醛缩N(4)-甲基-氨基硫脲,用元素分析、IR、1HNMR、紫外可见光谱等方法对化合物进行了表征及结构确证,并用对化合物的变色机理进行了探讨。

A novel compound of salicylaldehyde N（4）-methyl-thiosemicarbazone with photochromism in the solid state was synthesized and characterized by crystal structure,element analysis,IR,1H NMR and Time-dependent UV-Vis reflection spectra.An intramolecular proton transfer phototautomeric mechanism along the hydrogen bridge bond was proposed.
