Vapour-phase thioethers play an important role in a wide number of fields, including plant biology, chemical weapon disposal, and brewing but few sensor materials are known. The emissive coordination polymer CuAuCN does not react with vapour phase dimethyl sulphide (DMS) or diethyl sulphide (DES) despite the independent synthesis of emissive CuAuCN and CuAuCN from their constituent components in solution. However, the doped CuAuCN rapidly reacts in the solid state with both of these vapour phase thioethers reversibly, with a change in emission from 380/560 nm to 460 nm (DMS) or 420 nm (DES), illustrating that doping the inactive parent CuAuCN with Cu(i) generates an active sensor material. This response can be thermally cycled with little to no loss in functionality. CuAuCN, CuAuCN, and CuAuCN were structurally characterized as 3-D network structures supported by aurophilic interactions.
气相硫醚在包括植物生物学、化学武器处理和酿造在内的众多领域中发挥着重要作用，但已知的传感器材料却很少。发光配位聚合物CuAuCN不与气相二甲基硫醚（DMS）或二乙基硫醚（DES）反应，尽管在溶液中由其组成成分独立合成了发光的CuAuCN和CuAuCN。然而，掺杂的CuAuCN在固态下与这两种气相硫醚都能快速可逆地反应，发射光从380/560 nm变为460 nm（DMS）或420 nm（DES），这表明用Cu(i)掺杂无活性的母体CuAuCN可生成一种活性传感器材料。这种响应可以进行热循环，功能几乎没有损失。CuAuCN、CuAuCN和CuAuCN的结构表征为通过亲金相互作用支撑的三维网络结构。
