Abstract
Anion-π interactions between the Lewis basic anion fluoride and π-acidic naphthalene diimide was systematically studied in a series of cyclophanes in which the properties are modulated through the influence of a second, electron-rich aromatic unit. The systems and subsequently generated radical anions, upon addition of fluoride, were studied by absorption spectroscopic and EPR techniques. The results infer a modulation as a result of the nature and strength of the π-π interaction in the macrocyclic structure.
