Abstract

A set of (Ln[14-MC-5])LnZn(quinHA)(ph)(Hph)(OH)(HO) metallacrowns (, Ln = Tb, Gd, or Yb; HquinHA = quinaldic hydroxamic acid, Hph = phthalic acid) have been synthesized via solution-state self-assembly. The metallacrowns possess an uncommon topology within the metallacrown family where two rarely seen 14-metallacrown-5 moieties are fused by a YbZn(quinHA) bridge. Moreover, analyzed in the solid state exhibits a characteristic near-infrared luminescence signal arising from Yb F→F transition despite the proximity of high energy O-H oscillators.

摘要

通过溶液态自组装合成了一组（Ln[14-MC-5]）LnZn（quinHA）（ph）（Hph）（OH）（HO）金属冠醚（其中，Ln = Tb、Gd或Yb；HquinHA = 喹哪啶异羟肟酸，Hph = 邻苯二甲酸）。这些金属冠醚在金属冠醚家族中具有不常见的拓扑结构，其中两个罕见的14-金属冠-5部分通过YbZn（quinHA）桥相连。此外，尽管存在高能O-H振荡器，但在固态下分析显示出由Yb F→F跃迁产生的特征近红外发光信号。
