The host–guest complexation between a porphyrin‐based 3D tetragonal prism ( H ) and electron‐rich pyrene is investigated. This host–guest molecular recognition is further utilized to suppress the liquid‐crystalline behavior of a nematic molecule ( G ) containing cyanobiphenyl mesogens functionalized with a pyrenyl unit. Furthermore, coronene, with an increased number of π‐electrons, is used as a competitive guest to recover the liquid‐crystalline behavior of G . This supramolecular approach provides a glimpse of the new possibilities to modulate the structures of the mesophases.
