Chloride, acetate and benzoate anions binding with relatively low affinities are kinetically trapped between the straps within the cavity of a doubly strapped calix[4]pyrrole receptor. The complexation is accompanied by a conformational change of the host reminiscent of an insect being captured in a Venus flytrap.
