Résumé
A family of p-cyclophanes based on bis- or tetrafunctionalized 1,4-bisthiophenol units linked by disulfide bridges was obtained by self-assembly on a gram scale and without any chromatographic purification. The nature of the functionalities borne by these so-called dyn[4]arenes plays a crucial role on their structural features as well as their molecular recognition abilities. Tuning these functions on demand yields tailored receptors for cations, anions, or zwitterions in organic or aqueous media.
