1,4-二(2-苯并(口恶)唑基)苯及其衍生物紫外光谱和荧光光谱的溶剂效应

Effects of Solvents on UV Spectra and FL Spectra for 1,4-Bis(Benzoxazol-2-yl)Benzene and Its 5,5’-Disubstituted Derivatives

测定了1,4-二(2-苯并(口恶)唑基)本及其5,5′-二取代衍生物共八种化合物在十五种溶剂中的紫外吸收光谱及1,4-二(2-苯并(口恶)唑基)苯在九种溶剂中的荧光发射光谱。用二元回归分析和两类溶剂参数的双参数方程处理数据,得到了较一元回归和单参数方程更好的相关关系。

The UV spectra of 1,4-Bis(benzoxazol-2-yl)benzene and seven 5, 5’-disubs-tituted derivatives in fifteen solvents were determined. The FL spectra of 1,4-bis-(benzoxazol-2-yl) benzene in nine solvents were also determined. By treating the data with dual regression analysis, as compared with by treating with mono-regression analysis, the better correlation coefficients were obtained. By introducing the degree of relative transformation, the solvent effects on the change of shape of fluorescence spectra have been discussed.
