'Organically-Derivatized Polyoxometalates: Tuning of Bioactivity by Ligand Functionalization'


Polyoxometalates (POMs) are discrete polynuclear metal oxides with a large structural and compositional variety, and a multitude of properties resulting in applications in fundamental and applied science.1

In recent years our group has developed the class of organoantimony(III)-containing POMs and we have demonstrated bioactivity with a focus on bacterial inhibition. Most importantly, it was shown that the number and type of grafted organoantimony(III) groups have a strong influence on the resulting bioactivity of the polyanion.2

Here we show recent developments in this area of research.
