Optical characteristics of some fluorinated poly(1,3,4-oxadiazole-ether)s in presence of SnO2, NiO and SnO2/NiO mixed-oxide nanoparticles (NPs) was investigated. The interactions between polymers and metal oxide NPs were studied by steady-state UV-Vis absorption and fluorescence spectroscopy techniques. The absorption and fluorescence signals of all investigated polymers was modified by presence of both pure and mixed-oxide nanoparticles. The moderate values of Stern-Volmer quenching constant and non-linear trend of Scott plot indicate the less affinity between metal oxide NPs and polymers. The solvation behavior of some fluorinated poly(1,3,4-oxadiazole-ether)s in chloroform-N,N-dimethylformamide and N,N-dimethylformamide-dimethylsulfoxide mixtures was discussed.
研究了一些含氟聚（1,3,4 - 恶二唑 - 醚）在存在二氧化锡、氧化镍和二氧化锡/氧化镍混合氧化物纳米颗粒（NPs）时的光学特性。通过稳态紫外 - 可见吸收和荧光光谱技术研究了聚合物与金属氧化物纳米颗粒之间的相互作用。所有研究聚合物的吸收和荧光信号都因纯氧化物纳米颗粒和混合氧化物纳米颗粒的存在而发生了改变。斯特恩 - 沃尔默猝灭常数的适中值以及斯科特图的非线性趋势表明金属氧化物纳米颗粒与聚合物之间的亲和力较低。讨论了一些含氟聚（1,3,4 - 恶二唑 - 醚）在氯仿 - N，N - 二甲基甲酰胺和N，N - 二甲基甲酰胺 - 二甲基亚砜混合物中的溶剂化行为。
