R. Stiller et Jm. Lehn, SYNTHESIS AND PROPERTIES OF SILVER(I) AND COPPER(I) HELICATES WITH IMINE-BRIDGED OLIGOBIPYIDINE LIGANDS, EUROPEAN JOURNAL OF INORGANIC CHEMISTRY, (7), 1998, pp. 977-982
Oligobipyridine ligands containing one or two imine bridges were found
to form double helicates by treatment with copper(I) or silver(I). Th
e properties of the complexes are similar to those of oxapropylene-bri
dged oligobipyridines. Titration of a mixture of the bis(bipyridine) a
nd the tris(bipyridine) Ligands with silver(I) hexafluorophosphate sho
wed that helicates formed with strict self-recognition.
