Some Spectroscopic and Thermodynamic Studies of Charge Transfer Comlexes of DDQ and Some Phenol Derivatives


The π→π* charge transfer(CT) complexes of 2,3-dichloro-5,6-dicyanobenzoquenone (DDQ) with some phenol derivatives have been investigated spectraphotometrically in chloroform solution. The equilibrium constant (K) and extinction coefficient (ε) and the dissociation energies of the complexes excited state (w) of charge transfer have been calculated and discussed. The ionization potential of phenol derivatives have estimated.
