摘　　要：制备了钼取代的keggin型结构杂多酸H_5SiW_(11)Mo·xH_2O(SiW_(11)Mo),采用紫外-可见吸收光谱及傅里叶红外光谱对合成的杂多酸进行了表征。研究了取代型杂多酸及其与聚乙烯吡咯烷酮(PVP)形成的复合物的光致变色性能。通过正交实验,确定了影响复合物光致变色的关键因素及最优实验条件。结果表明:SiW_(11)Mo复合前后都具有可逆光致变色性,复合后的光响应速度和光致变色效率都明显提高。The compound H5SiW11 Mo · XH2O with Keggin structure is prepared and characterized by means of FTIR and UV -vis. The photochromic properties of the heteropoly acid and composite contained polyvinylpyrrolidone （PVP） and SiW11Mo are investiga By means of orthogonal experiment, we determine the optimized experimental condition. The results show that the heteropoly acid and composite have reversible photochromic properties before and after complex reaction. For product after complex reaction, their photochromic efficiency and respond speed are excellently improved.
