Abstract
The photochemical behavior of β-diketonates of boron difluoride in poly(methyl methacrylate) was studied. Excimers of boron chelates are formed in the course of UV irradiation of polymer compositions accompanied by a bathochromic shift of the luminescence spectrum. The intensification (quenching) of luminescence of the polymer compositions during irradiation depends on the ratio of the quantum yields of the monomer and excimer luminescence of boron difluoride β-diketonates.
