A simple pyrene-based triazole receptor has been synthesised and shown to self-assemble in the presence of ZnCl(2) in an exclusively 2:1 ratio, whereas a mixture of 2:1 and 1:1 ratios are observed for other Zn(2+) salts. The pyrene units are syn in orientation; this is supported by a strong excimer signal observed at 410 nm in the presence of ZnCl(2) in acetonitrile. DFT calculations and 2D NMR support the proposed structure.
已经合成了一种简单的基于吡咯的三唑受体，并在存在 ZnCl(2) 的情况下观察到其以 2:1 的比例自组装，而对于其他 Zn(2+)盐则观察到 2:1 和 1:1 的比例混合物。吡咯单元呈顺式取向；这得到了在乙腈中存在 ZnCl(2) 时观察到的在 410nm 处的强激基缔合物信号的支持。DFT 计算和 2D NMR 支持所提出的结构。
