Stilbene-bridged tert-butylcalix[4]arene as photoswitchable molecular receptors.
Using a designed control of conformations of tert-butylcalix[4]arene between cone and pinched cone, a highly selective receptor for small electron-deficient molecules with photoswitching binding ability was attained. [reaction: see text]
