Atmospheric pressure deposition of fluorine-doped SnO2 thin films from organotin fluorocarboxylate precursors

Abstract: Nine organotin fluorocarboxylates R n SnO 2 CR f (n = 3, R = Bu, R f = CF 3 , C 2 F 5 , C 3 F 7 , C 7 F 15 ; R = Et, R f = CF 3 , C 2 F 5 ; R = Me, R f = C 2 F 5 ; n = 2, R = Me, R f = CF 3 ) have been synthesized; key examples have been used to deposit fluorine-doped SnO 2 thin films by atmospheric pressure chemical vapour deposition. Et 3 SnO 2 CC 2 F 5 , in particular, gives high-quality films with fast deposition rates despite adopting a polymeric, carboxylate-bridged structure in the solid state, as deter… Show more

“…Similarly to triorganotin(IV) trifluoroacetates discussed (vide supra), there are two characteristic quartets in the 13 C NMR spectra, first one at 161.0 ppm (COO) with coupling constant 2 J( 19 F, 13 C) ¼ 38.5 Hz and the second one at 115.9 ppm (CF 3 ) with naturally higher coupling constant 1 J( 19 F, 13 C) ¼ 282.2 Hz. Only one signal in 19 F NMR spectrum at À75.0 ppm attributed to the CF 3 moiety is found. According to the 13 C and 19 F NMR spectra we suggest on the equality of both CF 3 COO substituents in solution.…”

“…The exceptional structure is that of Me 2 Sn(O 2 CCF 3 )(OH 2 ), i.e. featuring the somewhat electron-donating tin-bound methyl groups [66]. Here, the carboxylate ligands form quite asymmetric bonds to tin with two Sn-O bonds, i.e.…”
