铝氧团簇的诱导聚集、溶剂调控和超团簇组装研究OA

Cluster materials have attracted considerable attention due to their atomically precise structures,uniform size distribu-tion,and solution processability.Research on Al(Ⅲ)chemistry not only contributes to better understanding for the aggregation and evolution mechanisms of aluminum in environmental systems but also offers new opportunities for developing low-cost functional mate-rials,leveraging aluminum's high natural abundance.However,compared to other metal clusters,the crystallization of aluminum-based clusters is hindered by the rapid hydrolysis kinetics of Al(Ⅲ)ions,leading to slower progress in this field.To address this bottleneck,the authors'team has recently achieved controlled hydrolysis of aluminum isopropoxide through alcoholysis reactions.By proposing strategies of"induced aggregation,solvent regulation and supracluster assembly",we have successfully established the alu-minum oxo clusters(AlOCs)with varied structural types and functionalities.This review focuses on the latest research achievements in the field of AlOCs.Firstly,the concepts of"induced aggregation,solvent regulation and supracluster assembly"are explained.Subsequently,it provides a detailed discussion on the directional construction,size expansion,structural transformation of aluminum molecular rings,as well as their supramolecular assembly behaviors at the molecular level.Finally,the review demonstrates their po-tential applications in both solid and liquid phases,including iodine capture,optical limiting response,and utilization as dopants in polymer dielectrics.The strategies proposed in this work exhibit notable universality,which not only facilitates advancements in clus-ter science but also establishes a foundation for functional applications in related fields.
