  PbCl2、PbBr2 和混合卤化铅（Cl、Br、I）PbXnY2−n 薄膜的原子层沉积

  摘要：

  原子层沉积在具有高纵横比特征的基板上提供出色的薄膜均匀性和保形性。这些品质对于应用于串联太阳能电池、晶体管和发光二极管的混合卤化物钙钛矿薄膜至关重要。混合卤化物钙钛矿的光学和电子特性可以通过调节不同卤化物的比例来调节。到目前为止，ALD 仅能够沉积碘基卤化物钙钛矿，而其他卤化物工艺则缺乏。我们描述了用于 PbCl 2和PbBr 2的六种新的低温 (≤100 °C) ALD 工艺，它们是使用 ALD 沉积混合卤化物钙钛矿的关键步骤。双[双(三甲基甲硅烷基)酰胺]-GaCl 3和-TiBr 4铅工艺分别产生最纯净、结晶、均匀和保形的 PbCl 2和PbBr 2薄膜。我们表明，这两种工艺与文献中的 PbI 2工艺相结合可沉积混合卤化铅薄膜。四种不太理想的工艺表明，卤化铅沉积工艺中的反应副产物可能会导致薄膜蚀刻或将它们自身结合到薄膜中。

  N-Silyl-aminotin trichlorides, R¹R²N-SnCl₃[R¹ = R² = SiMe₃ (1a), R¹ = SiMe₃, R² = ^tBu (1b), R = SiMe₃, R² = 9-borabicyclo[3.3.1]nonyl (1c), R¹R² = Me₂ SiCH₂CH₂SiMe₂ (1d)] were prepared by the reaction of tin tetrachloride with the respective bis(amino)plumbylenes, (R¹R²N)₂Pb 4. The analogous reactions with bis(amino)stannylenes, (R¹R²N)₂Sn 3, afforded only mixtures of the aminotin trichlorides 1 and bis(amino)tin dichlorides, (R¹R²N)₂ SnCl₂ 2 . The products were characterised by ¹H, ¹¹B, ¹³C, ¹⁵N, ²⁹Si and ¹¹⁹Sn NMR spectroscopy, and the NMR data of 1 were compared with those of the corresponding N-silylamino(trimethyl)tin compounds 8.

• Tin–carbon bond formation by simple addition of cyclic dienes to a bis(amino)stannylene: a mechanistic study
  作者：Michael Veith、Michael Olbrich、Wang Shihua、Volker Huch

  DOI：10.1039/dt9960000161

  日期：——

  The addition of cyclopentadiene and indene to Bu'NSiMe(2)NBu'Sn resulted in the formation of 'adducts' (X-ray structural characterisation) through tin-carbon bonding and hydrogen migration to one of the nitrogen atoms. In the cyclopentadienyl compound pi bonding is observed (Sn-C 2.47-2.76 Angstrom) whereas the indenyl derivative displays a sigma-bond (Sn-C 2.343 Angstrom). In a similar reaction of Bu'NSiMe(2)NBu'E (E = Ge or Pb) with cyclopentadiene either the starting compounds or plumbocene along with an amine were isolated. At room temperature the reaction between indene and the cyclic stannylene is an equilibrium, the rate constants of which were raised by a factor of 3.0 for the association and slowed by a factor of 4.2 for the dissociation when deuteriated indene was used. From the kinetic data, a concerted addition mechanism of the proton and the indenyl group is favoured over an ionic two-step mechanism. If the steric hindrance of the protic cyclic diene system is raised (pentamethylcyclopentadiene) no reaction between the stannylene and diene is observed.
