  The deposition of PbS and PbSe thin films from lead dichalcogenoimidophosphinates by AACVD

  摘要：

  Lead sulfide and lead selenide thin films have been deposited from dichalcogenoimidophosphinate lead (II) complexes by AACVD. The synthesis of the precursors, [Pb((S)PPh2)(2)N)(2)] and [Pb((Se)PPh2)(2)N)(2)], is reported and the single crystal X-ray crystal structure of [Pb((S)PPh2)(2)N)(2)] determined. The films were characterised by p-XRD and SEM. (C) 2016 The Authors. Published by Elsevier B.V.

  Group 14 metal complexes of heavy chalcogen-centered anions, M[((TePPr2)-Pr-i)(2)N](2) (5, M = Sn: 6, M = Pb) and M((TePPr2NPPr2Se)-Pr-i-Pr-i)(2) (7, M = Sn: 8, M = Pb), were synthesized in 64-89% yields by metathesis of alkali-metal salts of the ligands with group 14 metal dihalides. Crystallographic characterization of the complexes revealed that 5, 6, and 8 engage in metal ... chalcogen secondary bonds to generate dimers. whereas 7 is monomeric in the solid state. Multinuclear (H-1, P-31, Se-77, and Te-125) solution NMR data for these homoleptic complexes evinced dynamic behavior leading to the equivalence of the two ligand environments. The Pb-II complex 6was utilized as a single-source precursor to mi,,rometer-scale lead telluride particles via two divergent techniques: aerosol-assisted chemical vapordeposition of the cDmplex in THF/CH2Cl2 solution onto glass substrates yielded rectangular prisms, while solution injection of 6 in trin-oclylphosphine onto Si/SiO2(100) substrates heated to 200-220 degrees C resulted in the formation of wires. PXRD and EDX analysis of the products confirmed the phase purity of the PbTe materials.
