Abstract

Abstract: We describe synthesis routes from fluorinated ethylzinc alkoxides to ether adducts of fluorinated binary homoleptic zinc alkoxides with fluorinated residues such as OR F (OC(CF3 )3 ), OR HF (OC(H)(CF3 )2 ), OR HT (OC(CH3 )(CF3 )2 ), OR AF (perfluoroadamantoxy) and OR CY (OC(CF3 )(CF2 )5 ). Their structures depend on the nature of the fluorinated residue: perfluorinated alkoxides OR XF tend to give monomeric ether adducts (ether)2 Zn(OR XF )2, while partially fluorinated residues OR YF lead to dimers of type (ether)( YF RO)Zn(μ‐OR YF )2 Zn(OR YF )(ether). The monomeric (Et2 O)2 Zn(OR F )2 was tested for its possibility to form fluorine doped zinc oxide upon thermal decomposition in inert atmosphere. Indeed, upon thermal degradation, homogenously doped materials (EDX mapping) with fluoride contents of 5.5 to 6 weight‐% form (EDX, ion chromatography). Abstract : A simple process for the preparation of a series of highly and per‐fluorinated zinc alkoxides is presented. Evidence for the application of (Et2 O)2 Zn(OR F )2 (R F =C(CF3 )3 ) as molecular single source precursor for fluorine doped zinc oxide is presented.
