From Siderophores and Self-Assembly to Luminescent Sensors: The Binding of Molybdenum by Catecholamides

Research output: Contribution to journalLiterature reviewpeer-review

Abstract

Molybdate reacts readily and instantly with 2,3-dihydroxy-benzamide-containing ligands (catecholamides) to give stable cis-dioxido-Mo-VI complexes. This reaction is of biological relevance, because it results in the competition of molybdate with Fe-III for siderophores of the catecholamide type. These siderophores are secreted by bacteria to acquire essential Fe-III and help the cells to cope with variations in metal ion concentrations in their environment. This microreview summarises the insights obtained in this area and analyses the structures of the Mo-VI complexes formed. In addition, the scope of the structure-defining potential of the cis-dioxido-Mo-VI unit in the self-assembly of supramolecular structures is illustrated. The final part of the review describes how catecholamide units can be used in the development of luminescent chemosensors for molybdate. ((C) Wiley-VCH Verlag GmbH & Co.
