【摘要】 分别以2种V形羧酸[1,3-苯二甲酸（H₂BDC）和5-羟基-1,3-苯二甲酸（H₂OIP）]与钼酸铵进行反应,得到了2种有机酸根与无机酸根缩合构成的杂化砷钼酸盐:（NH₄）₁₇H₄[(AsMo₆O₂₁)₂(AsMo₆O₂₃)（BDC）₄]·28H₂O（1）和（NH₄）₅Cs₈H₆[(AsMo₆O₂₁)₃（OIP）₅]·40H₂O（2）.利用单晶X射线衍射对2种化合物进行了结构分析,发现二者均为三聚结构.对2种化合物的光致变色及热致变色性质进行了研究,发现在氙灯照射下2种化合物均可在5 min内变色.当将2种化合物的样品加热到373 K时,均出现颜色变化,并随着温度升高颜色逐渐加深.光致变色与热致变色过程前后的EPR检测结果均提示化合物的颜色变化与Mo^VI转化为Mo^V有关.更多还原

【Abstract】 Benzene-1,3-dicarboxylic acid（H₂BDC） and 5-hydroxy-1,3-benzene dicarboxylic acid（H₂OIP） have been employed to synthesis two organic-inorganic hybrid arsenomolybdates,（NH₄）₁₇H₄[(AsMo₆O₂₁)₂(AsMo₆O₂₃)（BDC）₄]·28H₂O（1）and（NH₄）₅Cs₈H₆[(AsMo₆O₂₁)₃（OIP）₅]·40H₂O（2）. X-Ray crystallographic study indicated that both of the two compounds are trimers. The photochromic properties have been studied. Under the irradiation of a Xe-lamp,the two compounds changed their colors within 5 min. The thermochromic study of the two compounds indicated that they changed color at 373 K,and their color deepened on the increase of temperature.更多还原
