The challenge for atomic-level control of multi-aluminum structures for the development of new efficient materials

铝因其极端的多功能性和独特的性质，包括酸度、硬度和导电性，引起了人们的极大关注。本研究以Keggin和Dawson型空位多金属氧酸盐为无机配体，合成了具有单铝和多铝中心的各种铝化合物。对于铝配位的多氧钨酸盐分子氧催化水中醇类的氧化反应，铝中心附近的结构对其催化活性有显著影响。此外，阳离子有机锆片段被成功地负载到多金属氧酸盐中构建的铝中心上，这是利用铝中心作为原子级载体来负载多氧阴离子负载金属有机化合物的第一个例子。

Aluminum has attracted considerable attention because of their extreme versatility and unique range of properties, including acidity, hardness, and electroconductivity. In this study, various aluminum compounds possessing mono- and multi-aluminum sites were synthesized by using Keggin and Dawson-type lacunary polyoxometalates as inorganic ligands. For the oxidation of alcohols in water catalyzed by aluminum-coordinated polyoxotungstates with molecular oxygen, the activities were significantly affected by the structures around aluminum sites. Furthermore, a cationic organozirocnium fragment was successfully supported onto the aluminum site constructed in polyoxometalate; this is the first example of the polyoxoanion-supported organometallic compound by utilizing the aluminum site as an atomic-level support.
