摘要

采用紫外光谱和荧光光谱研究了木质素模型化合物愈创木酚(guaiacol)在[C4mim]Cl-H2O体系中的溶解行为。分析了[C4mim]Cl-H2O二元体系和[C4mim]Cl-H2O-guaiacol三元体系的谱图

发现在不同[C4mim]Cl浓度下

紫外光谱中芳香环的K带与B带的变化不同

对愈创木酚的溶解影响也不相同;愈创木酚的加入会使[C4mim]Cl-H2O出现荧光猝灭现象

其原因在于愈创木酚与[C4mim]Cl-H2O形成氢键

此弱分子间作用力影响了溶液的光谱行为。

Abstract

The dissolution behavior of guaiacol which used as model compounds of lignin in [C4mim]Cl-H2O was investigated by UV spectra and fluorescence spectra. By analyzing the spectrogram of [C4mim]Cl-H2O binary system and [C4mim]Cl-H2O-guaiacol ternary system

the results show that the change of K band and B band of aromatic ring in UV spectra were different in different concentration of [C4mim]Cl

which affects the dissolution of guaiacol. The addition of guaiacol induced fluorescence quenching

because guaiacol forms hydrogen bond with [C4mim]Cl-H2O and weak intermolecular interactions affect the spectral behavior of solutions.
