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.
