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

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
