Facile synthesis, precise species control and chemical transformation of highly conducting organic metal chalcogenides Cu_xBHT (BHT = benzenehexathiol; x = 3, 4, and 5.5)

Abstract

The design of conducting organic metal chalcogenides (OMCs) have attracted extensive attention for their applications in diverse areas. However, only a handful of OMCs exhibit appealing electrical transport properties due...

The Increasing Number of Electron Reservoirs in Nonporous, High‐Conducting Coordination Polymers CuxBHT (x = 3, 4, and 5, BHT = Benzenehexathiol) for Improved Faradaic Capacitance

“…Cu x BHTs were synthesized by changing stoichiometric ratios of Cu 2 O to BHT according to our group's previous report. [ 16 ] As shown in Figure a–c, the XRD patterns of Cu 3 BHT, Cu 4 BHT and Cu 5.5 BHT prepared by Cu 2 O and BHT are exactly the same as previously reported, [ 13,15 ] indicating that they have the same crystal structure. Furthermore, the element analysis and XPS results prove that the obtained samples have the same chemical composition as the previously reported samples (see Synthesis of Cu x BHT and Figure S1a–c, Supporting Information).…”

“…In addition, it has been found that Cu 4 BHT and Cu 5.5 BHT can be converted into Cu 3 BHT by chemical oxidation. [ 16 ] This prompted us to explore whether the electrochemical method can complete this transformation. The results show that Cu 4 BHT and Cu 5.5 BHT can be easily converted to Cu 3 BHT by simply performing a CV cycle within −1.2 to 0.5 V. As illustrated in Figure S19a,b (Supporting Information), the XRD patterns of Cu 4 BHT and Cu 5.5 BHT both show the peak corresponding to Cu 3 BHT located at 2θ = 26.1°, revealing the occurrence of the structural transformation.…”

Construction of conducting bimetallic organic metal chalcogenides via selective metal metathesis and oxidation transformation

“…Previous studies have shown that the structural transformation achieved by chemical oxidation was a synthetic shortcut to prepare OMCs 21 . To testify the universality of this chemical transformation strategy for OMCs, valence-variable cerium ammonium nitrate ((NH 4 ) 2 Ce(NO 3 ) 6 , CAN) was employed as the oxidizing reagent here (Methods, Supplementary Fig.…”

Highly Conductive Organic–Inorganic Hybrid Silver Sulfide with 3D Silver–Sulfur Networks Constructed from Benzenehexathiol: Structural Topology Regulation via Ligand Oxidation

“…Most of the reported conductive CPs with this type of ligand have two typical 2D structure patterns, one is a honeycomb structure with a ligand-to-metal ratio of 3:1 , and the other is a Kagomé lattice with a molar ratio of 3:2. , Despite their excellent performance, unfortunately, the lack of structural diversity and the finite choice of such ligands limit their wider research to a certain extent. However, our recent study on Cu–BHT CPs , shows that using the same metal nodes and organic ligands a series of (Cu x BHT) n ( x = 3, 4, 5.5) with different structures can be synthesized by regulating the oxidation levels of the ligands. Newly synthesized (Cu 4 BHT) n and (Cu 5.5 BHT) n have 3D structures, which are different from other conductive CPs based on BHT-like ligands.…”
