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
提出了构象适应性大环,即zorb [4]芳烃,其以多种构象存在于未络合状态。zorb [4] arene的结合腔被隐藏,这是由于构象塌陷或自我包裹。具有长烷基链的zorb [4]亚芳基表现出令人惊讶的低熔点,因此在室温下以油形式存在。客体分子的结合诱导了zorb [4] arene的折叠和构象刚性,并导致定义明确的三维结构,这些结构可以在溶剂蒸发后进一步自组装成纳米片或纳米管,具体取决于客体分子及其构象可以诱发。
