Exciplexes of Fluorinated and Methylated Derivatives of Dibenzoylmethanatoboron Difluoride with Benzene and Toluene on the Surface of Trimethylsilylated Aerosil

It has been shown that the introduction of electron-donating or electron-withdrawing groups in the para-position of dibenzoylmethanatoboron difluoride (DBMBF2) makes it possible to control the fluorescenсe characteristics of fluorophore exciplexes with methylbenzenes (MB). The fluorescent properties of DBMBF2/MB exciplexes at the gas–solid interface have been studied using the example of DBMBF2 adsorbed on the surface of trimethylsilylated aerosil.
