Abstract

Charge-transfer complexes of some heteroarylthiourea derivatives with π-accptors have been studied spectrophotometrically in CH<sub>2</sub>Cl<sub>2</sub>. Spectral data, stability constants and enthalpies of complexation are reported. From the energies of the CT transition, ionization potentials of the donors have been obtained. Effects of donor molecular structure, π-acceptor electron affinity and nature of solvent on <i>K</i><sub>CT</sub> of complexes are investigated and discussed. It is deduced that the formed CT complexes are of <i>n</i>-π kind and of 1 : 1 stoichiometry.
