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