Novel water-soluble bowl-shaped cyclophanes 1 and 2 were synthesized. Complexation study in 25% aqueous methanol revealed that 1 and 2 form 2:1 (host/guest) complexes with 1-anilinonaphthalene-8-sulfonate (ANS). The emission wavelength of ANS encapsulated by 1 and 2 as well as the related monocyclic cyclophanes was usefully employed to demonstrate that the host/guest ratio of the complex significantly affects the micropolarity of the guest-binding site of these cyclophanes.
