Abstract
It was demonstrated that, in contrast to a solution in an organic solvent, the relaxation of the excited state of a fluorophore moiety proceeds mainly radiationless upon the formation of naphthalimide fluoroionophore complexes with complementary cations in a monolayer on a water surface. Apparently, this is due to the fact that the distribution of the energy levels of molecular orbitals in the fluoroionophore complexes with cations at the air-water interfaces changes in such a way that relaxation of the excited state via charge transfer within the complex molecule remains possible.
