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 π-electronic systems, whose conformations were controlled by anion binding. Anion complexes of the oligopyrrole-based chiral π-electronic systems exhibited anion-dependent chiroptical properties, as seen in circular dichroism.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
