centres. Calixsalens form tail-to-tail dimers that are assembled into higher-order structures in the solid state. The formation of these dimers is accomplished by enantioselective self-recognition of chiral calixsalen units driven by non-covalent interactions only.

芳烃。Calixsalen的形成是高度立体选择性的,产生的外消旋混合物包含在其立体成因中心具有绝对构型的all-R或all-S的同手性产物。杯形尾巴形成从尾到尾的二聚体,这些二聚体以固态组装成更高阶的结构。这些二聚体的形成是通过仅由非共价相互作用驱动的手性杯
