The effect of solvation on spectral-luminescence properties of 2,2-difluoro-4-methylnaphto-[2,1-е]-1,3,2-dioxaborine

Abstract

The processes of formation and dissociation of aggregates and formation of solvates of 2,2-difluoro- 4-methylnaphto-[2,1-е]-1,3,2-dioxaborine (1) with the chloroform molecule have been investigated by the methods of stationary and time-resolved spectroscopy. It has been revealed that, in the case of solutions in chloroform, a slow (within 1 h) dissociation of aggregates under the effect of solvent molecules takes place. It has been demonstrated that using chloroform as a solvent allows varying the content of luminophor aggregates in the polymeric composite and, thus, controlling the material spectral-luminescence properties.
