A molecular cage encapsulating gold nanoparticles is presented. Six benzylic thioethers are pointing into its cavity, stabilizing the particles in a 1 : 1 ligand-to-particle-ratio in excellent yields. They are bench-stable for several months and can withstand unprecedented thermal stress of up to 130 °C, documenting the advantages of the cage-type stabilization over open-chain analogues.
一种分子笼包裹金纳米粒子的结构被呈现出来。六个苄基硫醚指向其空腔，以 1:1 的配体与粒子比例稳定了这些粒子，产率非常高。它们在几个月内都非常稳定，可以承受高达 130°C 的前所未有的热应力，这证明了笼型稳定相对于开链类似物的优势。
