摘要:

基于有機(jī)分子的光、電、磁功能材料因其巨大的產(chǎn)業(yè)化前景，一直受到科技界的高度關(guān)注，已成為新世紀(jì)重要研究方向之一，也取得了一系列重大進(jìn)展。有機(jī)光電功能材料的研究涉及物理、化學(xué)、材料、信息、電子乃至生物學(xué)等，是名副其實(shí)的交叉學(xué)科。在有機(jī)光電材料的研究中，一個重要的目標(biāo)就是搞清材料結(jié)構(gòu)與性能之間的關(guān)系，利用一系列先進(jìn)的方法和工具，對材料的各級結(jié)構(gòu)信息進(jìn)行表征，找到材料特定性能與結(jié)構(gòu)之間的內(nèi)在聯(lián)系，為材料的設(shè)計(jì)與改性提供必要的依據(jù)。晶體學(xué)作為一個已經(jīng)誕生百年的方法，在這一進(jìn)程中起到了關(guān)鍵的作用。從對材料作用機(jī)理的認(rèn)識，到結(jié)構(gòu)與功能關(guān)系的探討，以及功能材料的定向設(shè)計(jì)，都需要晶體學(xué)知識和方法。本文以我們課題組近年來在有機(jī)光電材料研究過程中一些比較有代表性的工作為例，展示了晶體學(xué)在探明材料的光電性能與結(jié)構(gòu)之間的關(guān)系，特別是研究一些材料特殊性質(zhì)的起源中不可或缺的作用。

Abstract:

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 in organic optoelectronic materials is an inter discipline subject that 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 activities the crystallography played a critical role in terms of understanding of 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 and structural properties, especially in the investigations about the origins of some special phenomena.
