Schiff碱型的罗丹明B类衍生物的合成及晶体结构分析

Syntheses and Crystal Structure Analysis of Rhodamin B Derivatives Schiffbase Type

利用罗丹明B与乙二胺合成出一种新的6齿Schiff碱化合物,利用X-衍射和红外光谱对化合物晶体进行检测和表征,最后测定了不同p H值时的紫外吸收光谱,发现随着pH值的增加,吸光度也随着增加。

In this paper,a new Schiff base compound was formed by the Rhodamin B and ethylenediamine.The crystalline structure of the compound was characterized in the X-ray diffraction and FT-IR spectrum.Finally,UV absorption spectra of different pH value were determined,and it was found that the UV absorption increased with the pH increasing.
