Problems solved by technology

Thin films can be fabricated by PCVD (Plasma-Induced Chemical Vapor Deposition) and sputtering, but these methods have structural problems and photoelectronic quality problems (T.W.F.Russel, B.N.Baron and R.E.Rocheleau, J.Vac.Sci.Technol.B2(4 ), 1984, 840; Sanjay Mathur, Hao Shen, Vladimir Sivakov, and Ulf Werner, Chem.

Embodiment 1

[0047] (Dimethylamino-2-methyl-2-propoxy)Sn(II)[Sn(dmamp) 2 ] preparation

[0048] SnCl at room temperature 2 (1g, 5.27mmol) and lithium bis(trimethylsilyl)amide [Li(btsa)] (1.76g, 10.54mmol) were charged into a 250mL Schlenk flask, ether (50mL) was added in the flask, and then Stir for 3 hours. The mixed solution was filtered to remove LiCl, and the solvent was removed from the filtrate under vacuum. at 10 -2 torr was fractionally distilled at 100°C to obtain Sn(btsa) 2 . Sn(btsa) 2 (1 g, 2.28 mmol) was dissolved in n-hexane. 2 equivalents of dimethylamino-2-methyl-2-propanol (0.53 g, 4.56 mmol) were slowly added thereto at room temperature, followed by stirring for 6 hours.

[0049] After removing the solvent under vacuum, at 10 -2 fractional distillation of torr at 100°C to obtain pure Sn(dmamp) 2 Compound (91%).

Embodiment 2

[0054] (Dimethylamino-2-methyl-2-propoxy)Sn(II)[Sn(dmamp) 2 ] preparation

[0055] SnBr at room temperature 2 (1g, 3.59mmol) and dimethylamino-2-methyl-2-propoxysodium [Na(dmamp)] (1g, 7.18mmol) were charged into a 250mL Schlenk flask, and THF (50mL ), followed by reflux for 12 hours. The mixed solution was filtered to remove NaCl, and the solvent was removed from the filtrate under vacuum. at 10 -2 Fractional distillation of torr at 100°C afforded pure compound (93%).

[0056] C 12 h 28 N 2 o 2 Sn H 2 Elemental analysis of O {calculated (measured)}: C, 39.05 (37.92); H, 8.19 (7.66); N, 7.59 (8.02)

[0057] Therefore, it was confirmed that the same compound as that of Example 1 was produced.

Embodiment 3

[0059] (Dimethylamino-2-methyl-2-butoxy)Sn(II)[Sn(dmamb) 2 ] preparation

[0060] SnCl at room temperature 2 (1g, 5.27mmol) and lithium bis(trimethylsilyl)amide [Li(btsa)] (1.76g, 10.54mmol) were charged into a 250mL Schlenk flask, ether (50mL) was added in the flask, and then Stir for 3 hours. The mixed solution was filtered to remove LiCl, and the solvent was removed from the filtrate under vacuum. at 10 -2 torr was fractionally distilled at 100°C to obtain Sn(btsa) 2 . Sn(btsa) 2 Dissolved in n-hexane. 2 equivalents of dimethylamino-2-methyl-2-butanol (0.59 g, 4.56 mmol) were slowly added thereto at room temperature, followed by stirring for 6 hours. After removing the solvent under vacuum, at 10 -2 fractional distillation of torr at 120°C to obtain pure Sn(dmamb) 2 compound (89%).

[0061] The Sn(dmamb) prepared in embodiment 3 2 compound 1 H-NMR is shown in Figure 5 middle.

Abstract

The present invention relates to novel tin amino-alkoxide complexes and a method for preparing the same, precisely novel tin amino-alkoxide complexes represented by formula 1 and useful as a precursor for tin and tin oxide thin films and a precursor for the production of nano-sized tin and tin oxide particles and a method for preparing the same. [Formula 1] Sn[O-A-NR1R2] 2 In formula 1, A is linear or branched (C2-C10) alkylene substituted or not substituted with halogen; R1 and R2 are independently linear or branched (C1-C7) alkyl substituted or not substituted with halogen.

Description

technical field [0001] The present invention relates to novel amino-alkoxytin complexes, more precisely the present invention relates to aminoalkoxyl groups useful as precursors for tin and tin oxide thin films and for the manufacture of nano-sized tin and tin oxide particles Tin complexes and methods for their preparation. Background technique [0002] Tin oxide was first reported in 1976 and is known as a transparent conductive oxide having visible light transmittance, infrared reflectivity, and low electrical resistance. Because of these characteristics, tin oxide has been widely used in gas sensors, solar cell electrodes, and low-resistance glass coatings, among others. A number of research groups are investigating tin alkoxides, amides and chalcogenides in monomeric form and with 2- or 4-coordinated structures. For the manufacture of tin, tin oxide, and tin-containing materials, materials such as SnCl 4 , Sn(CH 3 ) 4 , (CH 3 ) 2 SnCl 2 , Sn(C 4 h 9 ) 2 (CHCOO...
