摘要: 合成了两亲配体2-十六氨基甲酰基-8-羟基喹啉(简称HHQ),研究了亚相酸度及金属离子对HHQ成膜性能的影响。金属离子的半径、电荷及核外价电子层结构不同是影响HHQLang-muir单分子层膜性能的本质原因。从含有Ni2+、Cu2+离子的亚相表面所制备的多层LB膜的吸收光谱中产生了一个新的吸收峰。

Abstract: Anew amphiphilic ligand,2-hexadecylcarbamoyl-8-hydroxyquinoline(HHQ) was synthesized.The characteristics of monolayer of HHQwas investigated on subphases with different acidities and with different metal ions.The difference of the characteristics of HHQmonolayer is dependent on the difference of radii,nuclear charges and the structures of valence shell of metal ions.The 20-laver LBfilms of HHQon each side of the substrate were prepared by spreading a solution of HHQin chloroform,and UV-Vis absorption spectra of the LBfilms were recorded.Transitional metal ions can form complexes with HHQon the air/water interface,but alkali and alkali earth metal ions cannot.
