Abstract
The rare earths are a group of elements ranging from cerium to lutetium (inclusive of lanthanum, yttrium and scandium), whose peculiar magnetic, spectroscopic and chemical properties have resulted in wide and extensive studies of their compounds. Their current and potential applications have stimulated great interest and include their use as luminescent probes, contrast agents for magnetic resonance imaging (MRI), diagnostic/therapeutic radioisotopes, as well as catalysts for the hydrolysis of DNA and RNA. Our studies have been inspired by these applications and have thus far produced novel polynucleating macrocyclic and acyclic Schiff's base chelates with unusual recognitive sites. These were synthesized by templated condensation reactions in the presence of rare earth salts, and were definitively characterized by single crystal X-ray diffraction. Structural, luminescence spectroscopic and decay dynamical results will be presented.....
