The readily available ex-chiral-pool building block (-)-isosteviol was combined with the C 3-symmetric platforms hexahydroxytriphenylene and hexaaminotriptycene providing large and rigid molecular architectures. Because of the persistent cavities these scaffolds are very potent supramolecular affinity materials for head space analysis by quartz crystal microbalances. The scaffolds serve in particular as templates for tracing air-borne arenes at low concentration. The affinities of the synthesized materials towards different air-borne arenes were determined by 200 MHz quartz crystal microbalances.
现成的外消旋手性池砌块(-)-异甜菊醇与 C3 对称平台六羟基三苯和六氨基三芴结合，提供了大而刚性的分子结构。由于这些支架具有持久的空腔，因此它们是通过石英晶体微天平进行顶空分析的非常有效的超分子亲和材料。这些支架特别可用作追踪低浓度空气中芳烃的模板。通过 200 MHz 石英晶体微天平测定了合成材料对不同空气传播芳烃的亲和力。
