| Abstract | ||
| The bis (P-substituted-2-methoxy aniline benzylidene-4-oxy) Octamethane was prepared and used as a donor to form 1:2 complexes with (2, 3-Dichloro-5, 6-dicyanobenzoquinone) (DDQ), respectively. The equilibrium constants (K), molar absorptive extinction coefficients (ε ) and the dissociation energies of the charge transfer complexes excited states (w) have been calculated and discussed. The ionization potentials of Schiff bases have been determined and has been concluded that these complexes are predominantly of the (n → π) type. | ||
