通过DSC曲线,IR光谱,电子光谱和XRD谱分析,发现12-钼磷酸与葡聚糖在水溶液中可形成黄色包合物.以ESR,XPS,IR和电子光谱等手段研究此黄色包合物在紫外光照射下的光致变蓝紫色,是由于其光电子转移反应产物多价态钼(Ⅵ,Ⅴ,Ⅳ)配合物呈蓝紫色,而另一产物带部分羰基葡聚糖为无色所致.由DSC曲线,电子光谱,IR光谱和XRD谱测试结果得知,随着光化反应产物的生成,两者分子间产生包合作用,从而提高光致变色的稳定性.
It was found by DSC, IR, EDS and XRD spectra that the inclusion complex of 12-molybdophosphoric acid and dextran could be formed in aqueous solution. The yellow inclusion complex was studied by means of ESR, XPS, IR and electron spectroscopy The photochromic blue-violet under UV irradiation is due to the blue-violet color of its multivalent molybdenum (VI, Ⅴ, IV) complex as the product of its photoelectron transfer reaction and the partial absence of some of its carbonyl-dextran Induced by DSC curve, electron spectroscopy, IR spectroscopy and XRD spectrum test results show that, with the photochemical reaction product generation, the inclusion of the two molecules to enhance the stability of photochromism.
