Abstract: The composition and structure of the title compound are verified by elemental analysis,UVVis and IR spectra. It forms a well-behaved monomolecular layer at the air-water interface. The surface pressure-molecular area isotherms depend on the pre-treatment. The UV-Vis spectra of the LB film indicate that molecular interaction come mainly from the same layer. Polarized UV-Vis spectra show that the porphyrin rings in the LB film are tilted to the film plane.

Key words: porphyrin, LB film, structure
