Aggregation-induced emission based on a fluorinated macrocycle: visualizing spontaneous and ultrafast solid-state molecular motions at room temperatureviaF⋯F interactions

Abstract

We report the first example of fluorinated macrocycle, where two adjacent6F-2macrocycles were linked by two C–F⋯F–C halogen interactions, which endowed the molecule with autonomous and rapid MFC reversibility, within 100 s, at room temperature.
