Amphiphilic hydroxamic acid 2-(4-decyloxyphenyl)-4-hydroxy-3-oxo-3,4-dihydroquinoxalin-1-oxide was synthesized. The conditions of the formation of hydroxamic acid and its lead, europium, cadmium, and copper salt monomolecular layers were studied. Multimolecular systems were prepared by the Langmuir Blodgett method from various solvents, including chloroform, carbon tetrachloride, and toluene. The films were characterized by small angle X-ray scattering, UV and IR spectroscopy, ellipsometry, and atomic-force microscopy. The UV data and monolayer compression isotherms showed changes in the state of hydroxamic acid in various solvents in the presence of light and in the dark. The suggestion was made that changes in solutions were related to aggregation phenomenon.
