Photoprocesses Behavior Of Some Biologically Active Bis-Oxadiazole Compounds

Abstract

The behavior of the absorption and fluorescence emission processes for
some bis-1, 3, 4-oxadiazole sulphonyl compounds were studied in toluene, ethanol
and di-methyl sulfoxide solvents. Fluorescence quenching processes of the
compound bis- [2, 2/-5 ethyl sulphonyl-1, 3,4-oxadiazole]-1,4-butane, (4-Et), in
toluene and ethanol using benzonitrile and benzophenone quenchers were studied
too. The complex quenching mechanism of 4-Et by benzophenone, according to
the obtained data, was proposed.
