Three types of naphthodifurans (NDFs) have been designed as active organic materials in organic field-effect transistors (OFETs), and one of them, naphtho[2,1-b:6,5-b′]difuran, has been found to show an excellent OFET mobility of up to 3.6 cm2 V−1 s−1. Based on the crystal-packing structure and theoretical analyses, we attribute the high carrier mobility of the NDF derivatives to large intermolecular interactions and small reorganization energies. The NDF compounds show very high thermal and electrochemical stability. Together with some previous studies, the present study indicates that fused furan compounds show a performance that is equal to or better than that of the corresponding thiophene compounds.
三种类型的萘并二呋喃 (NDF) 被设计为有机场效应晶体管 (OFET) 中的活性有机材料,其中一种萘并[2,1-b:6,5-b']二呋喃被发现可以显示出高达 3.6 cm2 V−1 s−1 的出色 OFET 迁移率。基于晶体堆积结构和理论分析,我们将NDF衍生物的高载流子迁移率归因于大的分子间相互作用和小的重组能。 NDF 化合物表现出非常高的热稳定性和电化学稳定性。结合之前的一些研究,本研究表明稠合呋喃化合物的性能等于或优于相应的噻吩化合物。
