Abstract:
A method for forming a fluorinated oxostannate film involves vaporizing a volatile fluorinated alkyltin compound having at least two hydrolytically sensitive functional groups or at least two reactive functional groups which are sensitive to oxidation at a temperature greater than 200° C.; providing a substrate; physisorbing or chemisorbing the fluorinated alkyltin compound onto the substrate; and exposing the physisorbed or chemisorbed fluorinated alkyltin compound to a sequence of hydrolysis, irradiation, and/or oxidation steps to form the fluorinated oxostannate thin film on the substrate. Fluorinated alkyltin compounds having formula (I) are also described, in which Rf is a fluorinated or partially fluorinated linear or branched alkyl group having about 1 to about 5 carbon atoms, X is a dialkylamino group having about 1 to about 4 carbon atoms, and n is 1 or 2: (RfCH2)nSnX(4-n) (I).
