Abstract
The interaction of styryl derivatives of pyridine N-oxides with proton donors in various solvents was studied. UV-Vis spectroscopy and thermogravimetric analysis were applied to determine the spectral and thermo-chemical characteristics of the resulting molecular complexes. The dependences of the thermodynamic parameters of the complexes on the N-oxide structure and on the solvating medium were established. The DSC method was used to determine the temperature and enthalpy characteristics of the desolvation and melting processes for both N-oxides and their complexes with proton donors.
