【摘要】 本文综述了光致变色信息存储原理和光存储材料螺吡喃的研究进展，合成了9种螺吡喃单体和一个螺吡喃共聚物。所合成的目标化合物结构式如下： 采用红外光谱、核磁共振氢谱和质谱分析对化合物结构进行了表征，并采用紫外光谱仪对目标化合物进行了吸收光谱、耐疲劳性、热稳定性、量子产率等光致变色性能研究。结果发现含羟基螺吡喃单体在紫外光下是无光致变色性的，而螺吡喃共聚物有良好的光致变色性质。更多还原

【Abstract】 The optical information memory principle of photochromic material and the research development are reviewed in the paper. Eight spiropyran monomers and one spiropyran polymer have been synthesized .The structures of the target compounds are as follows : Monomer:The structures of all the compounds are characterized by 1H NMR,IR and Ms. And the photochromic properties such as the absorpting spectra,fatigue resistance, thermal stability, quantium yeild ,etc. are investigated by UV, which shows that spiropyran monomers having hydroxy take on no photochromic properties in ultraviolet while the spiropyran polymer takes on good photochromic properties.更多还原
