Abstract
Dipyrromethane dimers linked via a boron-bridged 1,3-propanedione moiety exhibited efficient anion-binding abilities. Trifluoromethyl and pentafluorophenyl moieties substituted at the meso positions of dipyrromethane induced chirality in the ?-electronic systems, whose conformations were controlled by anion binding. Anion complexes of the oligopyrrole-based chiral ?-electronic systems exhibited anion-dependent chiroptical properties, as seen in circular dichroism. © 2025 American Chemical Society.
