Two different hybrid cavitand-resorcin[4]arenes are shown to be effective and selective receptors for the molecular inclusion of positively charged organometallic sandwichcomplexes of appropriate size. The binding constants of the 1 : 1 complexes formed with a series of neutral and positively charged metallocenes have been calculated using different titration techniques. The motion of the included

Water stabilized, deep cavitands with three walls and an open side are shown to be receptors for amines and ammonium cations bearing bulky aliphatic groups. The missing wall allows the binding of guests not accommodated by the four-walled counterparts.
