1,3‐Bis(pentafluorophenyl‐imino)isoindoline (AF) and 3,6‐di‐tert‐butyl‐1,8‐bis(pentafluorophenyl)‐9H‐carbazole (BF) have been designed as preorganized anion receptors that exploit anion–πinteractions, and their ability to bind chloride and bromide in various solvents has been evaluated. Both receptors AF and BF are neutral but provide a central NH hydrogen bond that directs the halide anion into a
