合成了杯[4]芳烃构建的双咪唑季铵盐化合物1(BIQ-Calix),利用表面压一面积(π-A)等温线、压缩/扩张循环等温线与膜弛豫等温线、紫外与红外光谱、原子力显微镜等手段研究了该化合物在空气/水相界面、空气/二元羧酸水溶液界面的成膜性能。结果表明:化合物1在水或者二元羧酸乙二酸,丙二酸,丁二酸水溶液的亚相表面均能很好的形成稳定的Langmuir膜,其崩溃压分别为24 mN·m-1,30 mN·m-1,33 mN·m-1和28 mN ·m-1,平均单分子面积分别为2.0 nm2,2.3 nm2,2.5 nm2和2.2 nm2,并能与二元羧酸阴离子一起转移到固体基片上形成LB膜,且化合物1形成的LB膜为H-聚集体。
Bisimidazolium quaternary based on calix [ 4 ] arene 1 ( BIQ-Calix ) was synthesized. Its Langmuir-Blodgett ( LB ) film on air/water surface or air/dicarboxylic acid interface were characterized by surface pressure-area isotherms, the compress and out-spread isotherms,and monolayer relaxation isotherms,the corresponding LB films were investigated using UV-Vis and FT-IR spec-troscopy and atomic force microscope(AFM). The results indicated that 1 could form stable monolayer or multilayer film on air/wa-ter,oxalic acid,malonic acid and succinic acid interface with the collapsed surface pressure were 24,30,33,and 28 mN·m-1 ,and the limiting area per molecule were 2. 0,2. 3,2. 5 and 2. 2 nm2 ,respectively. The hybrid LB films of 1 and dicarboxylic acid with H aggregate could be transferred to solid substrate successful.
