Abstract: The luminescent properties of boron difluoride enaminedibenzoylmethanates and their oxygen analogues in solutions and crystals were investigated. During the transition from dilute solutions to concentrated solutions and crystals, a significant bathochromic shift in the maxima of the luminescence and excitation spectra is observed. It is established that the luminescence of crystals and concentrated solutions has an excimer nature.

Keywords: boron difluoride complexes, luminescence, excimers.
