liability allows for exfoliation of the material which results in the dispersion of the active sites and the enhancement of the visible-light trapping capacity. Using this copper(II) coordination polymer, a series of click reactions were successfully conducted under household light irradiation in the air at room temperature. And 1,4-substituted triazoles were the single products in good yields. Moreover, the
已经开发出二维Cu(II)配位片。通过将设计良好的生色团连接基引入配位聚合物中,长的共轭体系导致最大的UV-vis吸收波长红移到可见光区域(最大550 nm)。相邻的板材通过π⋯π堆积和C–H⋯π相互作用以ABAB方式组装,从而形成三维结构。层间堆叠模式很重要,因为它的责任在于会剥落材料,从而导致活性部位分散并增强可见光捕获能力。使用这种铜(II)配位聚合物,在室温下在空气中的家用光照射下成功进行了一系列点击反应。1,4-取代的三唑是高收率的单一产品。而且,可以容易地从反应混合物中除去催化剂。
