Abstrakt: The attractive interaction between carbonyl oxygens and the π-face of aromatic surfaces was studied using N -phenylimide molecular rotors. The C═O···Ar interactions could stabilize the transition states but were half the strength of comparable C═O···C═O interactions. The C═O···Ar interaction had a significant electrostatic component but only a small orbital delocalization component.
