摘要
合成了两种新型的含三甲胺和十八叔胺阳离子基团的螺吡喃染料,采用核磁共振氢谱、质谱、二维谱等手段,对染料及其中间体进行了结构表征。利用紫外—可见光谱研究了化合物的光致变色性。结果表明,含三甲胺阳离子基团的螺吡喃染料具有逆光致变色性和酸致变色性;含十八叔胺阳离子基团的螺吡喃染料仅仅表现出正常的光致变色性。
Two novel spirpoyran dyes containing trimethyl amine and octadecylpropan amine cationic moiety were synthesized.The chemical structures of the dyes and their intermediates were characterized by API-ES-MS,1H-NMR,g-COSY and g-HSQC.The relationship between chemical structures and their photochemical properties were studied with UV-visible spectra.The results showed that spiropyran containing trimethyl amine cationic moiety exhibits negative photochromic properties and acidchromic properties,but the spiropyran containing octadecylpropan amine cationic moiety only presents normal photochromic properties.
