A nanowire array with two types of bromoplumbate chains and high anisotropic conductance

Abstract

Crystalline nanowire arrays would create great opportunity for novel electrical application. Herein, we report a metal halide-based crystalline nanowire array, which was the first example constructed from two types of bromoplumbate anion chains. The single crystal shows high anisotropic conductivity with semiconducting transport along the c axis and an insulating feature perpendicular to the c direction.

Crystal structure of the lead-containing organic–inorganic hybrid: (C18H26N2)3[Pb4I14(DMSO)2]·2DMSO

“…Organic-inorganic hybrid materials have attracted more and more attention from researchers because of their interesting physical properties and novel functionalities, such as magnetism, ferroelectricity, electrical/optical properties and photochromism (Yao et al, 2017). The inorganic components provide rich structural possibilities, including discrete clusters, chains, layers and open frameworks, which dominate the significant electrical, optical and magnetic properties in hybrids (Sun et al, 2018). The organic moieties may exhibit unique molecular properties such as hyperpolarizability, photochromicity and polymerizability (Tang & Guloy, 1999).…”

Two-Dimensional and Emission-Tunable: An Unusual Perovskite Constructed from Lindqvist-Type [Pb6Br19]7– Nanoclusters

“…The whole size of the [Pb 6 Br 19 ] 7– cluster is about 1.23 × 1.23 × 1.23 nm 3 , which is much larger than the Lindqvist-type metal–oxygen clusters in polyoxometalate chemistry (Figure S2). As far as we know, such a Lindqvist-type [Pb 6 Br 19 ] 7– cluster is very scarce, although various haloplumbate clusters have been reported so far …”

Porous and Water Stable 2D Hybrid Metal Halide with Broad Light Emission and Selective H2O Vapor Sorption

“…Sun et al. reported the formation of a 1D structure consisting of two types of metal clusters [Pb 18 Br 54 ] n 18n− (chain 1) and [Pb 6.5 Br 19 ] n 6n− (chain 2) based on PbBr 6 octahedra [76] . Li et al., synthesized a 2D metal halide material consisting of a Lindqvist‐type [Pb 6 Br 19 ] 7− cluster of PbBr 6 octahedra [77] .…”

“…Sun et al reported the formation of a 1D structure consisting of two types of metal clusters [Pb 18 Br 54 ] n 18nÀ (chain 1) and [Pb 6.5 Br 19 ] n 6nÀ (chain 2) based on PbBr 6 octahedra. [76] Li et al, synthesized a 2D metal halide material consisting of a Lindqvist-type [Pb 6 Br 19 ] 7À cluster of PbBr 6 octahedra. [77] The same group reported the acquisition of a quite interesting 3D metal halide material constructed from an unprecedented Lindqvist-type highly coordinated [Pb 6 Br 25 ] 13À cluster based on six-, seven-and eight-coordinate Pb 2 + atoms.…”
