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
一系列的轴承融合到TTF芯(二甲氧基羰基和苯基邻苯二甲酰亚胺或新基硫富瓦烯(TTF)衍生物6和15 - 18)已被合成为潜在可溶半导体材料的有机场效应晶体管(OFET)。吸电子取代基降低了HOMO和LUMO能级的能量,并增加了半导体材料的溶解性和稳定性。还描述了所有新的TTF衍生物的晶体结构,并进行了理论DFT计算,以研究在OFET中使用的晶体的潜力。在实验研究中,性能最佳的器件表现出的空穴迁移率高达7.5×10 -3 cm 2 V -1s -1)。
