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...pi interactions were investigated, and these factors play significant roles in the complexation of these hostguest systems.
