摘要: 本文测试了两个三苯二(口恶)嗪化合物在18种溶剂中的电子吸收光谱和荧光发射光谱。计算了这些化合物的荧光量子产率。发现化合物的荧光光谱的νmaxF与溶剂的(n2-1)/(2n2+1)和ET(30)以及化合物的荧光光谱的Stokes位移△νs与溶剂的ET(30)均存在着良好的线性关系。醇类溶剂与溶质间的氢键作用以及含卤素溶剂的“外部重原子效应”导致化合物的荧光量子产率明显减小。

Abstract: The fluoiescence spectra of two triphenodioxazines in 18 solvents were studied.The fluorescence quantum yields of the compounds were calculated.It was found thatthe νmaxF of the fluorescence spectra of the compounds varied linearly with the (n2-1)/(2n2+1) and ET(30) of the solvents.The Stokes’ shifts vs of the fluorescence spectra of the compounds varied linearly with the ET(30) of the solvents.The hydrogen bonding interaction between the alcohol solvents and the solutes and the "external heavy atom effects" of the halogenated solvents decreased the fluorescence quantum yields of the compounds.
