不同溶剂中POPOP的荧光光谱及其特性研究
首发时间:2013-12-13
摘要:本文研究了POPOP在苯、二氧六环、乙酸乙酯、四氢呋喃、三氯甲烷、N,N-二甲基甲酰胺、吡啶和丙酮8种溶剂中的荧光光谱以及POPOP在四氢呋喃溶液中的光谱特性。结果显示,随溶剂极性增强,POPOP的荧光峰逐渐红移,由此计算得出POPOP在相应的8种溶剂中的跃迁能 。通过不同浓度的POPOP在在四氢呋喃中光谱特征,揭示了其在该溶液中的发光机理。

Study on the fluorescence spectra characteristic of POPOP in different solvent
Abstract:The fluorescence spectra of POPOP in benzene, dioxane, ethyl acetate, tetrahydrofuran, chloroform,dimethylformamide, pyridine and acetone solvents were studied. The results showed that the fluorescence peak of POPOP gradually shifts to long wavelength with the increased solvent polarity and the transition energies were calculated according to maximum peaks. Fluorescence spectra characteristics of POPOP in tetrahydrofuran solution reveals its luminescence mechanism.
Keywords: 1,4-bis-2-(5-phenyloxazolyl)-benzene fluorescence spectra solution effects
