Spectral studies for some charge transfer complexes Derived from Oxadiazole compounds and some electronic acceptors

Abstract

New charge-transfer (CT) complexes are prepared derived from 1,2,4 and 1,3,4-Oxadiazoles compounds as donor molecules with three acceptors molecules dinitrobenzene, 2,4,6-trinitro benzene and 2,4,6 trinitrophenol. The formation of CT complexes were identified by FT-IR , melting points and UV-Vis spectra. The type of bonding between the donor and acceptor depends on the interaction between components were studies by UV-Vis spectra . The physical parameters of CT complexes have been estimated at the max of each of them. From using Benesi-Hildebrands equation at 25 oC,the equilibrium constant and thermodynamic parameters have been calculated.
