一系列三个基于噻吩-萘的不对称低聚物—5-癸基-2,2′:5′,2′′:5′′,2′′′-四噻吩(DtT),5癸基-5′′ (萘-2-基)-2,2':5',2''-噻吩(D3TN)和5-(4-癸基苯基)-5'-(萘-2-基)-2,2'- Bithiophene(DP2TN)-是通过Suzuki交叉偶联反应合成的。烷基长链提高了低聚物在溶剂中的溶解度和自组装趋势。UV / Vis吸收测量表明DtT,D3TN和DP2TN形成了具有面对面堆积结构的H型聚集体。此外,发现这三种低聚物在沉积在基材上的薄膜中采用垂直排列的晶体结构,这通过掠入射广角X射线散射可以看出。这些低聚物被用作p型有机场效应晶体管的有源层,DtT为-3 cm 2 V -1 s -1,D3TN为1.6×10 -2 cm 2 V -1 s -1,DP2TN为3.7×10 -2 cm 2 V -1 s -1。晶体管性

Noble small molecules composed of an aromatic phenylene-trithiophene and naphthalene-trithiophene conjugated core were synthesized and examined for their property in p-type OFET devices. The phenylene and naphthalene moieties were combined with a trithiophene to introduce torsional structures into the conjugated core and improve the solubility compared with the solubility of the quaterthiophene core
合成了由芳族亚苯基-三噻吩和萘-三噻吩共轭核组成的贵族小分子,并在p型OFET装置中检查了它们的性能。亚苯基和萘部分与三噻吩结合以将扭转结构引入共轭核中,并且与含四噻吩核的分子的溶解度相比,提高了溶解度。尽管含亚苯基-三噻吩和萘-三噻吩的分子显示出较低的迁移率(分别为2.9×10 -3和1.04×10 -2 cm 2 / V),比含四噻吩的分子(3.21×10 -2 cm 2)更低/ V),由于溶解度的提高,它们显示出更高的薄膜均匀性。使用TGA,DSC,循环伏安法和XRD技术研究了热稳定性,光化学性质和形态特征。
