A catenated anion receptor 7 comprising two indolocarbazole units was prepared by olefin ring-closing metathesis using Grubbs' catalyst. Receptor 7 possesses a cage-like cavity where anions are encapsulated by forming four hydrogen bonds in the order of Cl- > AcO- > N3- > H2PO4- > Br- > HSO4- > I- ≈ NO3- in 1% H 2O/acetone.
