Metacyclophanes were prepared by cyclization reactions between bis(chloromethyl) compounds and piperazine, primary amines, or ethylene glycol. The 1H nmr relaxation time (T1) measurements indicated that the macrocycles feature the up and down motion of the aromatic units around the XCH2Ar (X = N, O) methylene moieties as the axes. Metacyclophanes incorporating piperazine units showed high complexation
