Synthesis and Characterisation of the Sodium and Lithium Cryptates of Macrobicyclic Ligands Incorporating Pyridine, Bipyridine, and Biisoquinoline Units

Synthetic procedures have been developed for the preparation of sodium and lithium cryptates of the macrobicyclic ligands 1-11 containing pyridine, bipyridine, and biisoquinoline groups.They involve stepwise construction of the bicyclic system as well as direct macrobicyclisation procedures (Scheme 1) and give access to both symmetrical and dissymmetrical structures.Marked cation template effects have been found that facilitate the cyclisation processes.The ligands 1-11 were isolated as their cryptates with Na+ or Li+ cations.

New 2,2'-Bipyridine Derivatives and Their Luminescence Properties with Europium(III) and Terbium(III) Ions

Twenty differently substituted 2,2',2",2"'-III and TbIII ions.The relative luminescence yields, excitation maxima, and emission decay constants were determined for the corresponding EuIII and TbIII chelates.The substituents at the bipyridine moiety had a significant effect on the luminescence properties: the best relative luminescence yields R were obtained for ligands with electron-donating substituents (e.g.Me, Ph), electron-withdrawing substituents (e.g.NO2, COOH) had a reverse effect.However, no clear correlation between the relative luminescence yields and the substituent parameters was found.
