纳米级无机轮状结构是分子聚集体中最引人注目的类型之一。在这里，我们报告的合成一个巨大的镧系元素轮团簇含有140 Gd 3+原子。{Gd-140}是迄今为止报道的最大的镧系元素簇合物，具有10重对称性的轮状结构。纳米级分子轮具有最大直径6.0 nm，在溶液中显示出高稳定性，这使得扫描透射电子显微镜可以直接观察。新发现的镧系{Gd-140}团簇是分子轮家族的新成员。
Nanoscale inorganic wheel-shaped structures are one of the most striking types of molecular aggregations. Here, we report the synthesis of a gigantic lanthanide wheel cluster containing 140 Gd3+ atoms. As the largest lanthanide cluster reported thus far, {Gd-140} features an attractive wheel-like structure with 10-fold: symmetry. The nanoscopic molecular wheel possesses the largest diameter of 6.0 nm and displays high stability in solution, Which allows direct visualization by scanning transmission electron microscopy. The newly discovered lanthanide {Gd-140} cluster represents a new member of the molecular wheel family.
