Nonsymmetrically Substituted Uranyl-Salophen Receptors: New Opportunities for Molecular Recognition and Catalysis

Abstract

This short review highlights recent results in the chemistry of nonsymmetrically substituted uranyl-salophen complexes with specific reference to their synthesis and properties. Their use as receptors and catalysts is also emphasized. The possibility of modulating their structure within wide limits by choosing the proper substituted aldehydes and/or ketones as starting materials, coupled with their inherent chirality offers new appealing opportunities for their applications.

Keywords:

• Nonsymmetrical salophen ligands
• Uranyl tetradentate Schiff base complexes
• Uranyl ion
