Abstract
Thallium salens can be synthesized by reacting thallium alkoxide with a salen ligand. As examples of the invention, the dinuclear complexes Tl-(salo-Bu) and Tl-(saloPh-Bu) were synthesized by the reaction of thallium ethoxide with (H-salo-Bu) or (H-saloPh-Bu). These thallium salens may have applications as fluorescent tracers (or taggants) for subterranean fluid flows.
