摘　　要：生命系统通过精确地调控组装过程,根据实际需求将有限的原料组装成具有不同聚集结构的材料,极大地丰富了材料的形式与功能.对分子组装的热力学环境与动力学聚集速率进行独立且精确地调控,是组装得到各种功能材料的关键.本文简单介绍了本课题组利用溶剂重结晶策略,通过控制重结晶的温度及温度变化率在精确控制溶剂分子组装过程方面的研究进展.Living systems have the capacity to effectively regulate the assembly of molecules into natural materials with outstanding functionalities via controlling the assembly process.Inspired by nature,great efforts have recently been focused on controlling the assembly process,not only enriching materials formats,but also assisting further understand the complex assembly mechanisms.In this review,we firstly introduce the current considerable progresses via tuning the assembly process,as well as illustrating that the reported strategies are insufficient to regulate precisely the assembly process because it is difficult to independently control the thermodynamics of assembly and molecular assembly rates.Then we summarize our recent research progress on precise controlling the molecular assembly process via a novel method,solvent recrystallization.The two key parameters,recrystallization temperature and temperature change rate,can independently control the assembly thermodynamic environment and molecular aggregation rates.Thus,the same assembly units including small molecules and polymers can be assembled into desired materials with controllable sizes and adjustable molecular packings.
