Resorcin[4]arene cavitands are well-known supramolecular hosts, and their outstanding guest-binding abilities in solution have been studied in detail in recent decades. In a systematic approach, different resorcin[4]arene cavitands and container molecules are characterized as affinity materials for gravimetric sensing using high-fundamental-frequency quartz crystal microbalances. Analysis of their affinity toward a series of various analytes reveals a remarkable dependence of both selectivity and sensitivity on the shape, accessibility, and size of the cavity, along with their supramolecular interactions with the host molecules.
间苯二酚[4]芳烃穴状配体是著名的超分子主体，近几十年来，人们对其在溶液中出色的客体结合能力进行了详细研究。采用系统方法，使用高基频石英晶体微天平将不同的间苯二酚[4]芳烃穴状配体和容器分子表征为用于重量传感的亲和材料。对它们与一系列不同分析物的亲和力分析表明，选择性和灵敏度都显著依赖于腔体的形状、可达性和尺寸，以及它们与主体分子的超分子相互作用。
