English abstract:
Novel surface-functionalized metal oxo clusters were obtained using an in situ surface-modification method based on the sol-gel process. A reaction of 2-bromoisobutyric acid with Zr(OPr)4 or Ti(OiPr)4 resulted in the compounds Zr5O4(BrC(CH3)2COO)10(OnPr)2(nPrOH)4 and Ti6O4(BrC(CH3)2COO)8(OiPr)8. The reaction of 2-bromopropionic acid with VO(OiPr)3 resulted in the cluster V3O3(BrC(CH3)COO)6(HOiPr). All obtained compounds have in common that the organic functionalities are exclusively located on the surface of the well-defined sub-nanometer metal oxo clusters. The prepared compounds were successfully used as macroinitiators in atom transfer radical polymerizations (ATRP) and produced inorganic-organic core-shell nanoparticles.
