A series of new tetrathiafulvalene (TTF) derivatives bearing dimethoxycarbonyl and phenyl or phthalimidyl groups fused to the TTF core (6 and 15-18) has been synthesized as potential soluble semiconductor materials for organic field-effect transistors (OFETs). The electron-withdrawing substituents lower the energy of the HOMO and LUMO levels and increase the solubility and stability of the semiconducting material. Crystal structures of all new TTF derivatives are also described, and theoretical DFT calculations were carried out to study the potential of the crystals to be used in OFET. In the experimental study, the best performing device exhibited a hole mobility up to 7.5 × 10(-3) cm(2) V(-1) s(-1)).
一系列新的四硫富瓦烯（TTF）衍生物具有二甲氧羰基和苯基或邻苯二甲酰亚胺基融合到 TTF 核心（6 和 15-18），作为潜在的可溶性半导体材料用于有机场效应晶体管（OFETs）。吸电子取代基降低 HOMO 和 LUMO 能级的能量，并增加半导体材料的溶解度和稳定性。所有新的 TTF 衍生物的晶体结构也进行了描述，并进行了理论 DFT 计算，以研究晶体在 OFET 中的应用潜力。在实验研究中，性能最佳的器件表现出高达 7.5×10(-3)cm(2)V(-1)s(-1)的空穴迁移率。
