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 i
nteraction with different cationic and anionic guests.
