【摘要】 苝酰亚胺是一类重要的有机N型半导体,具有非常高的荧光量子产率,非常好的电荷传输性能,在有机光电领域具有很大的潜在应用。苝酰亚胺本身中心核是一个大平面共轭体系,共轭使整体分子相较于其他一些具有相同性质的有机分子在热稳定性、光稳定性和化学稳定性上有更突出的表现。苝酰亚胺衍生物已经被研究者们广泛应用于功能性材料领域,已经涉及有机光电材料、分子探针、人工离子受体、有机纳米材料、药物载体等领域。由于可对其分子结构的优化修饰从而改变其光学、电荷传输等自身性质,因此针对苝酰亚胺分子进行官能团功能化的研究一直是研究者们研究的热门方向。随着研究的不断深入,对苝酰亚胺衍生物本身的性质也要求的愈加多样,对分子本身的设计愈加的复杂。对于其分子上的改性方法有很多途径。基于这些方法本文设计一系列苝核取代的分子,采用亲核性差异的三种有机分子:对叔丁基苯酚,对氟苯酚和对五氟苯酚进行亲核取代。并探索了苝酰亚胺湾位处多功能基团引入的途径与方法。进行了完整的结构、光学和电化学的表征。通过对分子之间的比较与总结获得一种不对称苝酰亚胺功能化的有效途径。进一步针对苝酰亚胺湾位进行了无机功能分子碳化钛的改性,并探索式的研究了其进行有机无机杂化后的性质与特征。结果表明非对称苝酰亚胺分子是可以通过设计得出,为以后多功能苝酰亚胺分子的研究进行了准备。关于其湾位无机杂化的研究也探索式发现了其与无机分子杂化后表现出更好的环境敏感性,以及创新的合成出了一种新型的二维空间杂化分子。更多还原

【Abstract】 The Perylene diimide derivatives is a kind of important organic N-type semiconductor used to be a great potential applications in the field of organic optoelectronics, which has a very high rate of quantity of fluorescent and very good charge transport properties. Perylene diimide derivatives is a big plane conjugate system,which has a more outstanding performance, compared to others with the same properties of organic molecules on the thermal stability, light stability and chemical stability. It has been widely applied in the field of functional material, such as organic photoelectric materials, artificial receptors, molecular probe, organic nanomaterials, drug carrier and other fields. Its functionalization research has always been a hot direction of the researchers study, due to chaging its structure modification can alter its optical and the charge transfer properties. With the deepening of the research on perylene diimide derivatives increasingly diverse requirements of the nature of itself, the design of molecules are more and more complicated.There are many ways to modify the molecule. Based on these methods, in this paper, a series of molecules have been designed though adding three small different nucleophilic molecules(4-tert-Butylphenol, 4-Fluorophenol and Pentafluorophenol). And the way to introduce the different functional groups at the bay of perylene diimide derivatives has been found. The structural characteristics, optical and electrochemical characterization also have been represented. Further more, the inorganic molecular of Ti3C2 was added to the bay of perylene diimide derivatives to explore the properties and characteristics.Results show that the asymmetric perylene diimide derivatives can be obtained by design. The study of the molecules for multi-function perylene diimide derivatives were prepared. The hybrid molecule shows better environmental sensitivity. And the innovertive synthesis of a new kind of two-dimensional space hybrid molecules has been obtained.更多还原
