Perfluorosulfonic membranes were modified by Schiff bases by sorption of molecules on sulfonic groups of the membranes and by coordination attachment to preliminarily implanted La 3+ cations. The fixation of the molecules in nanosized cavities of membranes is responsible for their luminescence at room temperature in a violet-blue spectral range. The choice of guest molecules of bases and the mode of their immobilization in a membrane provides certain possibilities of regulating the position of the de-excitation band of film luminophores.
