  Deposition of II‐VI Thin Films by LP‐MOCVD Using Novel Single‐Source Precursors

  摘要：

  AbstractThin films of several zinc or cadmium chalcogenides have been deposited on glass substrates by low pressure metal‐organic chemical vapour deposition (LP‐MOCVD) using single‐source precursors, [M{(EPiPr2)2N}2] (M = CdII, ZnII and E = S, Se). X‐ray single crystal structures show that [Zn{(EPiPr2)2N}2] (E = S or Se) and [Zn{(SePPh2)2N}2] are tetrahedrally distorted. TGA analyses showed that the precursors are volatile, making them suitable for MOCVD studies. As‐deposited films were polycrystalline as confirmed by X‐ray powder diffraction (XRPD) and their morphologies were studied by scanning electron microscope (SEM). (© Wiley‐VCH Verlag GmbH & Co.

For this series of complexes the phosphorus magnetic shielding tensors are essentially identical, the selenium magnetic shielding tensors are also very similar with respect to each other, and the magnetic shielding tensors of the central metals, cadmium and mercury, display

  Reaction of (Pr2PCl)-Pr-i with (Me3Si)(2)NH gives (Pr2PNHPPr2)-Pr-i-P-i (not isolated) which was oxidised with sulfur/selenium/oxygen to give (Pr2P)-Pr-i(E)NHP(E')Pr-i(2) (E, E'=Se; E=Se, E'=S; E=S, E'=O; E,E'=O). These neutral LH molecules readily undergo deprotonation/complexation to form simple ML, species and demonstrative examples with Zn, Cd, Pd, Pt are reported. The X-ray structure of two examples of (Pr2P)-Pr-i(E)NHP(E')Pr-i(2) (E, E' = Se, E,EI = O) are reported. The molecules pack into infinite chains via H...E Hydrogen bonds. The X-ray structures of three typical metal complexes which illustrate tetrahedral (Cd[((Pr2PSe)-Pr-i)(2)](2)) and square planar (Pt[N((Pr2PSe)-Pr-i)(2)](2)) coordination at the metal centre as well as the ability of the ME2P2N ring to adopt the pseudo-chair conformation (Pt[(Pr2P)-Pr-i(Se)NHP(S)Pr-i(2)](2)) are also reported.
