芘类有机半导体材料研究进展

由于芘具有大环共轭和易于修饰的特性,近年来,芘类共轭衍生物成为有机半导体的重要组成部分.最主要的文献报道为芘类电致发光材料,它们从化学结构上可分为四类材料：小分子、寡聚物、树枝状大分子和聚合物.其中小分子芘衍生物又可分为单取代衍生物、双取代衍生物和四取代衍生物.同时,近年来也有部分文献开始报道芘类材料在场效应晶体管、太阳能电池和其他方面的应用.文中按以上内容,分别进行了比较分析,最后提出了该类材料的未来发展方向.

Research Progress of Pyrene-Based Organic Semiconductor Materials

Pyrene derivatives have become an important component of organic semiconductors due to features of large conjugation and chemical modification.Till now,most of the electroluminescent materials can classified into four categories according to the chemical structure：small molecules,oligomers,dendrimers and polymers.Among them,the small molecules include mono-substituted,di-substituted,and tetra-substituted derivatives.Meanwhile,some literatures have reported the applications of pyrene derivatives on the organic field effect transistors,organic solar cells and others in recent years.The organic semiconducting pyrene derivatives are compared and analyzed in accordance with the above classification.Finally,the future development trend of such materials is pointed out.
