呋喃稠环类共轭有机分子和聚合物研究进展

摘要

目前,噻吩稠环衍生物及相关共轭聚合物作为有机半导体材料已经得到了较多的研究和应用.呋喃作为一种与噻吩杂原子同主族的五元环体系,与噻吩具有类似的化学结构和电子性质,但其具有芳香性更小、载流子迁移率高、荧光量子效率高和溶解性好的特点,得到了越来越多的研究和关注.本综述介绍了呋喃稠环共轭有机分子与呋喃稠环共轭聚合物的合成方法、性质及应用.%Currently,as organic semiconductor materials,thiophene fused ring derivatives and the related polymers have received considerable research and application.Furan has similar chemical structure and electronic properties with thiophene due to the same main group heterocyclic atom in five-membered ring system.But furan and furan derivatives possess smaller aromaticity,higher carrier mobility,higher fluorescence quantum efficiency and better solubility,thus more and more attentions have been paid to the design and synthesis of furan-containing fused rings for the application in organic optoelectronic materials.This paper reviewed the recent research progresses of the synthetic methods,properties and applications of the conjugated organic small molecules and polymers based on the furan-containing fused rings.
