Luminescence and sensory properties of PMMA films doped with a boron chelate

The optical sensory properties of polymethylmethacrylate films doped with 2,2-difluoro-4-methylnaphtho-[2,1- e ]-1,3,2-dioxaborine ( 1 ) for water vapor are found. A mechanism of the optical response is proposed: water molecules contribute through hydrogen bonds to the dissociation of aggregates of...

Description
Summary:The optical sensory properties of polymethylmethacrylate films doped with 2,2-difluoro-4-methylnaphtho-[2,1- e ]-1,3,2-dioxaborine ( 1 ) for water vapor are found. A mechanism of the optical response is proposed: water molecules contribute through hydrogen bonds to the dissociation of aggregates of 1 having intense excimer luminescence of J -aggregates. A sharp quenching of luminescence is observed. The spectrum of the films after exposure to water vapor corresponds to the monomer luminescence of 1 .
