Abstract
The stability constants K of 1 : 1 complexes formed in aqueous solutio n between several monosubstituted benzenes (C(6)H(5)X) and methanes (C H(3)X) as guests and cyclotetrachromotropylene as host were determined by proton NMR spectroscopy. Variations of K with the substituent X ar e attributed to the electronic effect of X and the presence of C-H or aromatic pi bonds, if any, interacting with the host pi bonds.
