Fluorophore-Functionalized and Top-Covered Resorcin[4]arene Cavitands

This review describes our recent developments in the field of resorcin[4]arene cavitands. We present the syntheses of cavitands bearing pyrene, anthracene, and BODIPY dyes as fluorophores on the cavitand walls. These systems have been used to examine the conformational switching process between the closed vase and the open kite forms that are characteristic for this class of cavitands. In a second research direction, we prepared top-covered resorcin[4]arene-based, switchable container molecules, and investigated their binding and switching properties.
