在过去的几十年里。有机电子学作为一个新兴领域迅猛发展,为科学技术的进步作出了巨大的贡献.有机材料被应用在各种电子器件中,并取得了卓越的成效.作为使用在电子器件中最基本的组分,有机光电材料更是备受瞩目.二嗪类化合物具有优异的光电性能,是光电材料领域最活跃的研究方向之一.两个N原子相对位置的不同,可以构成三种异构体,分别为哒嗪(1,2-二嗪)、嘧啶(1,3-二嗪)和吡嗪(1,4-二嗪),从而有效地调控材料的电子结构,且可以影响二嗪化合物不同位置的修饰,从而得到了广泛关注.本文对近年来二嗪类化合物在光伏材料、薄膜半导体材料、液晶材料、传感材料和电致发光材料等领域的研究进展进行了较全面的总结和评述,指出目前基于二嗪类化合物的光电材料所面临的困难以及未来的发展方向,最后展望了二嗪类化合物作为杂环类有机光电功能材料的应用前景.
As a new and developing field, organic electronics is attracting much attention and has contributed greatly to progress in science and technology over the past few decades. Satisfactory results have been achieved for the use of organic optoelectronic materials in various electronic devices. As the most basic component used in electronic devices, organic optoelectronic materials have attracted an increasing amount of attention. Diazine compounds have excellent optical and electrical properties and are some of the most researched compounds in the photoelectric material field. They contain a benzene ring in which two of the C--H fragments have been replaced by isolobal nitrogen. Three isomers: pyridazine (1,2- diazine), pyrimidine (1,3-diazine), and pyrazine (1,4-diazine) exist. Because of the relative position of two of the N atoms, they can be modified in different positions and can be effectively used to control the electronic structure of the material. Therefore, they have received widespread attention. In this review, a summary of recent research pro.qress into diazine compounds in different optoelectronic functional material application fields is provided. Specifically, photovoltaic materials, thin film semiconductor materials, liquid crystal materials, chemosensor materials, and electroluminescent materials are discussed. Finally, existing important problems and the future development of diazine compounds are also discussed.
