摘要 

溶液成核是影响晶体材料的理性设计与精准制备的关键过程,因而对于晶体成核的机理理解从而实现精准控制至关重要。晶体成核研究历经了几个世纪的发展,形成了经典成核理论与非经典成核机理2种主流学说。综述了近年来晶体成核分子机理方面的研究进展,首先简介了经典成核理论的发展及问题,重点介绍了溶液化学、多晶型及晶体成核的分子机理,引出了两步成核与成核团簇前驱体2种典型的非经典机理,总结了成核机理与控制在晶体设计中的应用。最后,对成核分子机理研究方面进行了总结与展望。

Abstract

Crystal nucleation from solution is a key process for the rational design and precise production of the desired structure and properties of crystalline materials. Understanding of crystal nucleation mechanism and hence the precise control is of fundamental importance. Crystal nucleation was studied for several centuries, and two main schools of thought, classic nucleation theory and non-classic nucleation mechanism, were proposed. The review summarized the research progress in recent years on molecular mechanism of crystal nucleation from solution. It was briefly introduced the development and problem of classic nucleation theory. Recent studies on solution chemistry, polymorphic formation and crystal nucleation mechanism were reviewed in detail. Two-step mechanism and pre-nucleation cluster pathway were then introduced, and the application of understanding and control of crystal nucleation was summarized. Finally, the future study on crystal nucleation mechanism was discussed and outlooked.
