  扩展用分子金属硫属化物配体封端的胶体纳米晶体的化学多功能性

  摘要：

  我们开发了不同的策略来合成用分子金属硫属化物络合物 (MCC) 稳定的胶体纳米晶体。带负电的 MCC，例如 SnS(4)(4-)、Sn(2)S(6)(4-)、SnTe(4)(4-)、AsS(3)(3-)、MoS(4) (2-)，可定量置换纳米晶表面的有机配体，稳定不同极性介质中的纳米晶溶液。我们展示了由金属、半导体或磁性材料组成并覆盖有各种 MCC 配体的全无机纳米晶体可以使用方便且廉价的化学品和环境友好的溶剂（如水、甲酰胺或二甲亚砜）合成。发现温和合成路线的发展对于高发光全无机纳米晶体的设计至关重要，例如分别用 Sn(2)S(6)(4-) MCC 封盖的 CdSe/ZnS 和 PbS。我们还从无机封端的胶体纳米晶体和聚电解质制备了导电和发光的逐层组件。在用 Na(2)Sn(2)S(6) 稳定的 5 nm Au 纳米晶体的密堆积薄膜中，我们观察到非常高的电导率 (>1000 S cm(-1))。

  Mesostructured chalcogenide-based materials with long-range order and semiconducting properties can be prepared using suitable molecular building blocks, linkage metal ions and surfactant molecules. In this paper we present surfactant templated, open framework platinum tin selenicle and telluride materials assembled using K(4)SnQ(4) (Q = Se, Te) salts and K2PtCl4 as precursors and a study of pore and wall organization. We find that materials prepared in water exhibit disordered pore organization, whereas those prepared in formamide are long-range ordered with hexagonal symmetry. In formannide the [SnQ(4)](4-) anions undergo condensation-oligomerization reactions that produce different chalcogenido molecular species, whereas in water the anions remain intact. In addition to solvent, the pore organization and overall quality of the mesostructured materials strongly depend on the surfactant molecules, i.e., chain length and headgroup size. For example, highly ordered mesostructured platinum tin selenides with hexagonal symmetry were obtained using the hydroxyl-functionalized surfactants CnH2n+1N(CH3)(CH2CH2OH)(2)Br (n = 16, 18, and 20), but when the headgroup was triethylammonium, hexagonal pore order was achieved only for n = 20 and not for n = 16 and 18. The experimental results imply that in order to achieve highly ordered chalcogenide frameworks a single building anionic block might be insufficient. Finally, we also report the first examples of hexagonal mesostructured Pt/Sn/Te materials based on K4SnTe4 as the precursor. The tellurides behave differently for their selenium analogues and have very low energy band gaps, in the range 0.5-0.7 eV.
