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.
