TL;DR: A series of N-arylimide molecular balances were designed to study and measure fluorine-aromatic (F-π) interactions, finding the attractive F-π interaction is electrostatically driven and is stronger than other halogen-π interactions.

Abstract: A series of N-arylimide molecular balances were designed to study and measure fluorine–aromatic (F–π) interactions. Fluorine substituents gave rise to increasingly more stabilizing interactions with more electron-deficient aromatic surfaces. The attractive F–π interaction is electrostatically driven and is stronger than other halogen–π interactions.
