摘 要：Nanoparticles of 1-pbenyl-3-naphthyl-5-((diniethylamino)phenyl)-2-pyrazoline were prepared using the reprecipitation method. We found that pyrazoline nanoparticles possess a special size dependence in their optical properties. The organic thin films of stearic acid/pyrazoline nanoparticles was prepared by transferring Langmuir m0onolayer of stearic acid/pyrazoline nanoparticle onto the solid substrate. The complex of stearic acid/pyrazoline nanoparticle was studied with pressure-area isotherm at me air/water interface and identified with linearly increasing optical absorbance around 370 nm by increasing the number of deposited layers. The in situ domain structure and molecular orientation of the complex were measured with BAM. The surface morphology of the Langmuir-Blodgett film was observed with AFM. The dispersion of pyrazoline nanoparticle in the film was studied with TEM.
