Polyaza[n]cyclophanes containing the 2,2′-biphenyl subunit are prepared in good yields by reaction of the corresponding pertosylated polyamine and 2,2′-bis(bromomethyl)biphenyl in basic media followed by detosylation with Na/Hg; the dynamic behaviour of those receptors is clearly affected by their interaction with different cationic and anionic guests.
