Luminescence of 4,7-diphenyl-1,10-phenanthroline forms bound in NAFION membrane

The fixation of 4,7-diphenyl-1,10-phenanthroline on walls of nanosized cavities of a Nafion perfluorosulfonic membrane was realized by two methods: by sorption of molecules on the sulfo groups of the membrane and by coordination attachment to previously grafted La 3+ and Tb 3+ cations. The bright luminescence of the molecule forms bound in the membrane is recorded at room temperature in the range of 400–500 nm.
