A simple pyrene-based triazole receptor has been synthesised and shown to self-assemble in the presence of ZnCl2 in an exclusively 2â:â1 ratio, whereas a mixture of 2â:â1 and 1â:â1 ratios are observed for other Zn2+ salts. The pyrene units are syn in orientation; this is supported by a strong excimer signal observed at 410 nm in the presence of ZnCl2 in acetonitrile. DFT calculations and 2D NMR support the proposed structure.
我们合成了一种简单的芘基三唑受体,并证明它能在氯化锌存在下以完全 2â:â1 的比例自组装,而在其他 Zn2+ 盐中则观察到 2â:â1 和 1â:â1 的混合比例。在乙腈中含有 ZnCl2 时,在 410 纳米波长处观察到一个强烈的准分子信号,证明了芘单元在取向上是同步的。DFT 计算和二维 NMR 支持所提出的结构。
