Cavity‐extended pillar[5]arenes containing electron‐rich naphthyl groups have been demonstrated to have enhanced binding affinity to linear guests containing electron‐deficient pyridinium units. The importance of size effect, charge density, cooperative effect, and C–H ··· π interactions were investigated, and these factors play significant roles in the complexation of these host–guest systems.
