晶体学在有机光电材料研究中的应用

The Applications of Crystallography in the Studies of Organic Optoelectronic Materials

基于有机分子的光、电、磁功能材料因其巨大的产业化前景,一直受到科技界的高度关注,已成为21世纪重要研究方向之一,也取得了一系列重大进展。有机光电功能材料的研究涉及物理、化学、材料、信息、电子乃至生物学等,是名副其实的交叉学科。在有机光电材料的研究中,一个重要的目标就是搞清材料结构与性能之间的关系,利用一系列先进的方法和工具,对材料的各级结构信息进行表征,找到材料特定性能与结构之间的内在联系,为材料的设计与改性提供必要的依据。晶体学作为一个已经诞生100年的方法,在这一进程中起到了关键的作用。从对材料作用机理的认识,到结构与功能关系的探讨,以及功能材料的定向设计,都需要晶体学知识和方法。结合作者课题组近年来在有机光电材料研究过程中一些比较有代表性的研究工作,阐述晶体学在探明材料的光电性能与结构之间的关系,特别是研究一些材料特殊性质的起源中不可或缺的作用。

Due to the huge industrial prospects of organic materials with optical, electrical, and magnetic functionalities, it has become an important research direction that attracted many researchers＇ interest and has produced a series of significant achievements. Research on organic optoelectronic materials is an inter discipline subject involving physics, chemistry, materials, information, electronics and even biology. One of the important goals in the study of organic optoelectronic materials is to find out the relationship between the specific properties and structures by using advanced methods and tools, which will provide necessary information for the design and modification of desirable functional materials. In these activi- ties the crystallography played a critical role in terms of understanding the working mechanism of the materials, exploring the relationship between structures and functionalities, and designing materials with specific functionalities. In this thesis, we present some work in our group about organic optoelectronic materials, with the purpose of showing the indispensable role of crystallographic in the process of exploring the relationship between the optical properties and structure, especially in the investigations about the origins of some special phenomena.
