Abstract

Spectral characteristics and thermodynamic properties of charge-transfer molecular complexes of some heteroarylthioureas with π-acceptors DDQ, TCNE and CHL are investigated and discussed. It is deduced that the formed CT complexes are of n-π kind. Moreover, 1:1 solid CT complexes are synthesized and characterized.
