| Outline of Final Research Achievements |
A molecular seesaw balance 1-MeI has been developed to measure pyridinium－π interactions. This balance adopts two distinct conformers, A and B, which are stabilized by a cation－π interaction and a π－π interaction, respectively. The conformer ratio was determined on the basis of the averaged 3J coupling constants for H1－C－C－H2 and the corresponding boundary J values for conformers A and B. The effects of the solvent and the counteranion on the ΔG values were investigated using this molecular balance. Thermodynamic parameters obtained from a van’t Hoff plot helped us to better understand the solvent and counteranion effects.
