摘    要:将Dawson结构的18-钼砷酸(As2Mo18)与喹啉形成的电荷转移盐分别与聚乙烯醇(PVA)和聚乙烯吡咯烷酮(PVP)进行薄膜组装,得到具有可逆光致变色性的H6As2Mo18O62·9C9H7N·1.5C2H6O/PVA和H6As2Mo18O62+9C9H7N·1.5C2H6O/PVP杂化薄膜,通过热重、IR、紫外-可见吸收光谱、循环伏安对杂化薄膜进行了表征,并对其光致变色性进行了研究。结果表明,光照后杂多酸与聚合物之间发生了电荷转移,杂多阴离子中的Mo^Ⅵ被还原为Mo^Ⅴ,同时聚合物被氧化。

关 键 词:杂多酸  喹啉  聚乙烯醇  聚乙烯吡咯烷酮  光致变色

Abstract:The charge-transfer complex of H6As2Mo18O62/quinoline was assembled in poly(vinyl alcohol) (PVA) matrix and polyvinylpyrrolidone(PVP) matrix. Two reversible photochromic hybrid films of H6As2Mo18O62·9C9H7N·1.5C2H6O/PVA and H6As2Mo18O·9C9H7N·1.5C2H6O/PVP were obtained. The two hybrid films were characterized by TG, IR, UV-Vis and CV. The results showed that the intervalence charge transfer(Mo^V→Mo^Ⅵ) underwent between the heteropolyacid and the polymer after UV irradiation of the hybrid films, accompanying with the reduction of Mow to Mov and simultaneous oxidation of the polymer.
Keywords:heteropolyacids  quinoline  poly(vinyl alcohol)  polyvinylpyrrolidone  photochromism
