氨基酸衍生物有机凝胶的X射线衍射行为研究

Research on Amino Acid Derivatives Organogels by X-ray Diffraction

以X射线衍射分析研究了氨基酸衍生物有机凝胶的凝胶态、干凝胶态和固态的凝胶分子的晶体差异,证明了在形成有机凝胶后,氨基酸衍生物类凝胶因子以自组装方式发生了重排,分子之间的相对位置发生了变化.因此,可以将X射线衍射分析作为判断有机凝胶自组装发生过程的判据,与傅立叶红外光谱(FT-IR)分析结合可以用于说明有机凝胶形成机理.

The crystal types of the gels,dry gels and gelators of amino acid derivatives were studied in X-ray diffraction analysis. We proved that after the formation of organogel,amino acid derivatives gelators rearrange by self-assemble and the relative position betw een the molecular changes. Therefore,X-ray diffraction analysis can be seen as the criterion to determine the organogel's self assembly process,combining w ith Fourier Transform Infrared Spectroscopy( ft-ir) analysis,it can be used to illustrate the mechanism of the formation of the organic gel.
