Formation of lanthanide luminescent di-metallic helicates in solution using a bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligand

Abstract

Bis-tridentate (1,2,3-triazol-4-yl)picolinamide ( tzpa ) was used to form Tb( iii ) double- and triple-stranded di-metallic helicates in solution, where changes in the absorption and the Tb( iii ) emission were used to monitor the formation of these supramolecular systems.
