Two carbazole disulfonamide-diamide macrocycles with semi-flexible meta-xylyl linkages for anion recognition

Abstract

Two novel carbazole disulfonamide-diamide macrocycles 1 and 2 with the semi-flexible meta-xylyl linkages were designed, synthesized, and assessed for their anion binding properties, via 1H NMR and UV-vis titration studies....

A Carbazole-1,8-Disulfonamide-Derived Cryptand Receptor for Anion Recognition

“…So far, a limited number of anion receptors employing the carbazole-1,8-disulfonamide moiety as the binding motif have been reported by others and us. − Clearly, all of these receptors can be categorized into cleft-shaped or cyclic geometries. To the best of our knowledge, the development of cryptand-like anion receptors based on the carbazole-1,8-disulfonamide moiety is still unprecedented.…”
