Abstract

The results of investigations of spectrally luminescent and acid-base properties of methoxysubstituted pyridiloxazoles 4PyOCH3PO and 4PyOCH3POCH2Ph+Cl- at optical excitation in solutions of different acidity and silicate thin films have been discussed. On the basis of comparison of the results of the carried out experiments and quantum-chemical calculation the possibilities of specific interactions of phosphor molecules by one or several from proton acceptor molecule centre (nitrogen atom of pyridine cycle, nitrogen and oxygen atoms of oxazole cycle and methoxy-(-OCH3) group) with solvate shell were analyzed. Quantitative features of bacisity characterizing efficiency of ion form formation were determined. Mechanisms of interaction of dye molecules with surface of nano-dimensional pores of polymeric silicate matrices were determined.
