我们精心设计了一种新策略，在室温下使用简单的溶液相方法在铜基板上形成倒锥形硫氰酸亚铜（以下简称CuCNS）阵列。该方法由硫氰酸铵溶液与铜基材本身在甲酰胺的协助下发生液固反应组成。新型 CuCNS 阵列大致垂直于铜基板表面。每个单晶都呈现出倒锥状的形态（即尖端指向铜基板的表面，锥体的另一大端暴露在外，就像一支飞镖刺入铜基板）。根据结构和化学键分析，CuCNS 晶体倾向于沿 c 轴生长，这对于在铜基板上形成 CuCNS 阵列至关重要。这种方法还提供了一种在不同铜基板上产生不同图案的简便策略，这可能适用于合成具有各种潜在应用的其他无机材料。
A new strategy has been well designed to form upended taper-shaped cuprous thiocyanate ( hereafter abbreviated as CuCNS) arrays on a copper substrate with use of a simple solution-phase method at room temperature. This method consists of a liquid-solid reaction between a solution of thiocyanate ammonium and the copper substrate itself in the assistance of formamide. Novel CuCNS arrays are approximately perpendicular to copper substrate surfaces. Every single crystal shows an upended taper-like morphology (i.e., the tip end points into the surface of copper substrate and the other big end of the taper exposes out, like a dart thrusting into the copper substrate). On the basis of structure and chemical bond analysis, CuCNS crystals tend to grow along the c-axis, which is essential for the formation of CuCNS arrays on a copper substrate. This approach also provides a facile strategy to produce different patterns on different copper substrates, which may be applicable to the synthesis of other inorganic materials with various potential applications.
