| Effect of Acidity and Polarity of Solvents on the UV-Visible Spectra of Amphiphilic Ligand |

| 摘要: 研究了溶剂的极性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带分裂为两个吸收峰。HL存在明显的浓度效应。非极性和弱极性溶剂对HL的紫外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. |
