Abstract
Charge transfer complexes of substituted aryl diphenylmethyl sulphides, X1C6H4(X2C6H4) CH—S—C6H4Y, with tetracyanoethylene, 2,3-dichloro-5,6-dicyano-p-benzoquinone and chloranil have been studied spectrophotometrically. The energy of the charge transfer transition is influenced by the substituents in Y, but is not affected by the substituents in X. The ionization potentials calculated from the energy of charge transfer transitions are in good accord with those measured by photoelectron spectroscopy. The nature of the donor orbitals is also discussed.Keywords
