Abstract
A number of terbium(III) homoleptic complexes exhibit reversible protonation reactions with strong acids, suggesting possible application as chemical sensors. One such species, Tb(bpy)2(NO3)3 (bpy = 2,2’-bipyridine), has been successfully synthesized in our laboratories and characterized by FTIR, NMR, and off-site elemental analysis. Crystal growth will allow the unambiguous elucidation of the structure. Upon protonation, the strong ultraviolet absorption signature is red-shifted by 0.30 eV. An acid titration in aqueous solution will give insight into the thermodynamic parameters governing the reversible reaction.
