STRUCTURE-ENERGY AND SOLVENT-PROPERTY RELATIONSHIPS FOR ELECTRONIC ENERGIES OF CHARGE-TRANSFER COMPLEXES BETWEEN CERTAIN BENZENE-DERIVATIVES

A chemical model is proposed for describing charge-transfer complexes between aromatic amines and electron-accepting benzene derivatives containing a group having a double- or triple-bond conjugated with the benzene ring. According to this model, an electron migrates from the nitrogen atom of the amine to one of the atoms of the multiple-bonded group during charge-transfer interaction. Structure-property relationships were derived. Equations were derived for correlating the effect of variation in solvent on the transition energies of the complexes.
