Abstract

An approximately linear correlation has been found between the enthalpy of complexation and the area of overlap of the chromophores using published structural and thermodynamical data on the self- and hetero-association of aromatic molecules measured under similar solution conditions. This finding is consistent with the assumption that short-range van-der-Waals forces dominate over other contributions to the enthalpy of stacking of aromatic molecules. It provides a 'model-independent' approach for a priori estimation of the enthalpy of aromatic-aromatic stacking interactions from knowledge of the structural properties or vice versa.
