摘　　要：以 12 -钼磷酸和碱性染料结晶紫为原料 ,制备了具有可逆光致变色特性的杂多配合物 ,根据 X-射线粉末衍射 ,红外、紫外及可见光谱、差热、热失重分析等手段的测试结果表明 ,该配合物中结晶紫与 12 -钼磷酸之比为 4∶ 1;有机阳离子与杂多阴离子间以配键形式相结合 ;配合物的光致变色性能是由于在光的照射下 ,发生了光电子转移反应 ,形成多价 Mo( , )Using 12-Molybdenum phosporic acid and crystal violet as raw material, the photochromism complex is synthesized and characterized by elemental analysis, X-ray powder diffraction analysis, IR and UV-Vis spectroscopy, TG-DTA thermal analysis. The results show that crystal violet not do coordinate with heteropolyanion, but with protons in heteropoly acid by coordination bond and the Keggin structure of complex do not change. Photochromism of complex undergoes electron transfer reaction on light to form multivalent molybdenum complex and accompanied by a color change from grin-green to blue.
