An oxa- and aza-calix[4]arene hybrid molecular cage with a large, shape-persistent cavity wrapped by aromatic rings was designed and synthesized via multifold efficient SNAr reactions. X-ray single-crystal analysis revealed that two THF molecules were encapsulated in the central cavity. Selective sensing of F- in apolar solvent leads to naked eye discriminable color change. Addition of CH3OH would recover the color of the molecular cage.
