Abstract

We report the synthesis and investigation of the vase–kite conformational switching of bridged calix [4] resorcinarene-based cavitands bearing iodo or ethynyl substituents on the upper rim of the cavity. These reactive centers make the cavitands versatile platforms for further modular extension by means of Sonogashira cross-couplings, thereby enabling the construction of diverse functional architectures that are switchable between two highly ...
