提出了一种构象自适应的大环化合物，即zorb[4]芳烃。zorb[4]芳烃的结合腔是隐藏的，这是由于折叠构象或自包含。具有长烷基链的zorb[4]芳烃表现出令人惊讶的低熔点，因此在室温下以油的形式存在。客体分子的结合诱导zorb[4]芳烃的折叠和构象刚性，并导致明确的三维结构，其可以在溶剂蒸发时进一步自组装成纳米片或纳米管，这取决于客体分子和它们可以诱导的构象。
A conformationally adaptive macrocycle is presented, namely zorb[4]arene, which exists in multiple conformations in the uncomplexed state. The binding cavity of zorb[4]arene is concealed, either due to a collapsed conformation or by self-inclusion. The zorb[4]arene with long alkyl chains manifests itself with surprisingly low melting point and thus exist as an oil at room temperature. Binding of a guest molecule induces the folding and conformational rigidity of zorb[4]arene and leads to well-defined three-dimensional structures, which can further self-assemble into nanosheets or nanotubes upon solvent evaporation, depending on guest molecules and the conformations they can induce.
