Spectral Study of some Charge Transfer Complexes Derivedfrom Schiff base of 3- Methoxy -4-hydroxy benzaldehydewith some Electrone acceptors

A new series of schiff bases were obtained by condensation of 3- methoxy -4-hydroxy benzaldehyde (vanillin) with seven aromatic amine .these bases were identified by infrared spectra and melting point . the effect of the substituents (x) on the amino ring has been studied . the charge transfer complexes (ctc) of the schiff bases as a donor molecules with various electron acceptors as(ddq ,p-ca ,o-ca ,-m-dn and pf (used for the first time as acceptor) in methylene chloride and methanol (solvent ) were estimated , the physical parameters of the ct complexes were calculated by applying the benesi –hildebrands equation for 1:1 ct complexes . the study also involved precipitation of one schiff bases (1)with three electron acceptors as ct complexes and identified these complexes by ir ,melting point, uv-visible and the colures .
