Ac. Try et al., REVERSIBLE 5-COMPONENT ASSEMBLY OF A [2]CATENANE FROM A CHIRAL METALLOMACROCYCLE AND A DINAPHTHO-CROWN ETHER, Chemical communications, (6), 1998, pp. 723-724
Addition of a dinaphtho-crown ether to the components of a chiral meta
llomacrocycle affords a [2]catenane as the exclusive thermodynamic pro
duct; the reversible assembly process is driven by a combination of zi
nc(II)-bipyridyl ligation and pi-donor/pi-acceptor interactions betwee
n the electronically complementary aromatic components.
