| Abstract | ||
| The complexes of some Schiff bases derived from p-N,N-dimethylaminobenzaladehyde and some p-anilines derivatives were used as charge donor withTetracyano-pquinodimethane(TCNQ) and2,3-dichloro-5,6-dicyano-1,4- benzoquinone (DDQ) as acceptors in 1,2-dichloroethanehave been study by UV-visible spectrophotometer . The physical parameters such as ionization potentials of Schiff bases and dissociation energies of charge transfer complexes excited state have been calculated at max. By using Benesi- Hildebrand's equation , the equilibrium constants and molar extinction oefficient for CT complexes also determined .Molecular compounds with acceptor are formed through n→*transition .The effect of temperature on the equilibrium constant and other thermodynamic parameters and the conductivity for the interaction of Schiff bases and TCNQ and DDQ (CT complexes) in C2H4Cl2 solution have also been considered. | ||
