Abstract
The recently published most complete set of thermodynamical data on self and heterocomplexation of aromatic molecules measured under comparable experimental conditions were analyzed The main aim of this study is to get insights into contribution of various entropic factors to pi stacking in aqueous solution It was found that the experimental entropy change on pi stacking is determined by counterbalancing effects of two principal factors ie the hydrophobic interaction positive contribution and the loss of degrees of freedom negative contribution modulated by the electrostatic contribution Other factors including the mixing entropy contribution were shown to be less important
