Macrocyclic BODIPY/dipyrrin tetramers and pentamers connected by m‐phenylene linkers were synthesized. Their uniquely folded shapes were revealed by a single‐crystal X‐ray diffraction analysis, and their dynamic structural behaviors in solution were investigated by variable‐temperature NMR measurements. The BODIPY oligomers exhibited strong emission properties without quenching. Furthermore, the BODIPY pentamer interacted with an ammonium cation utilizing the negatively charged binding pockets in which the polarized Bδ+–Fδ− bonds are present.
