摘要

Resorcin[4]arenes and related cavitands are bowl-shaped macrocyclic compounds possessing rigid cavities that enable highly selective molecular recognition. In this lecture text, we describe their structural principles, conformational behavior, and electronic properties, alongside key functional applications. Special attention is given to the resorcin[4]arene-based framework, which forms the cornerstone of modern cavitand design. The dynamic vase–kite equilibrium is discussed as a central conformational feature, influencing the host–guest interactions. Through selected examples, we illustrate how fine-tuning the cavitand structure leads to diverse and controllable recognition profiles, underlining their importance in the broader context of supramolecular chemistry.
