Wheel-shaped molecular rings are one of the most striking types of molecular aggregates due to their naturally aesthetically appealing architecture, giant size and interesting physical properties and potential applications. Herein, unlike common supertetrahedral cluster-based main-group metal chalcogenides, we report an unprecedented wheel-shaped double-decker {Ga₂₄S₄₀} molecular ring (WSC-1) with an ∼1.6 nm external diameter, which is the first main-group metal sulfide nanoring and the largest ring in the family of inorganic metal sulfide molecular rings. Furthermore, indium was successfully introduced to obtain the first bimetallic main-group metal chalcogenide molecular ring (WSC-1-In), exhibiting enhanced photocatalytic dye degradation. This work is of great significance to expand the family of metal chalcogenide molecular rings and demonstrated the great potential of metal chalcogenide molecular rings in the application of photocatalysis.

通过铟合金化增强光催化活性的轮状硫化镓分子环

轮状分子环是最引人注目的分子聚集体类型之一，因为它们具有自然美观的结构、巨大的尺寸以及有趣的物理特性和潜在应用。在此，与常见的基于超四面体簇的主族金属硫属化物不同，我们报道了一种前所未有的轮状双层{Ga ₂₄ S ₄₀ }分子环（WSC-1），其外径约为1.6 nm，这是第一个主要的主族金属硫属化物。 -族金属硫化物纳米环，是无机金属硫化物分子环家族中最大的环。此外，成功引入铟，获得第一个双金属主族金属硫族化物分子环（WSC-1-In）），表现出增强的光催化染料降解能力。该工作对于扩大金属硫族化物分子环家族具有重要意义，展示了金属硫族化物分子环在光催化应用中的巨大潜力。
