| 摘 要： | 研究了溶剂生和溶液的酸度对两亲配体Ｎ－十六烷基－８－羟基－２－喹啉甲酰胺（ＨＬ）紫外－可见光谱的影响。在碱性介质中，ＨＬ的吸收带＾１Ｂｂ、＾１Ｌａ和＾１Ｌｂ均产生红移；在酸性介质中，ＨＬ的吸收带不仅红移，而且＾１Ｌｂ带分开明为两个吸收峰。ＨＬ存在明显的浓度效应。非极性和弱极性溶剂对ＨＬ的紫餐可见光谱的影响服从Ｂａｙｌｉｃｓ方程；极性溶剂对ＨＬ的紫外可见光谱的影响服从ＭｃＲａｃ方程。

| Abstract: | The UV-visible spectra of an amphiphilic derivative of 8 hydroxyquinoline, N-hexadecyl-8 hydroxy 2 quinoline carboxamides were investigated. The positions of 1La and 1Bb bands of the derivatives were investigated as a function of solvent. Apparent concentration effect and acid base equilibrium in polar solvent were observed. |

| Keywords: | UV-visible spectra amphiphilic ligand polarity of solvents acidity |
