报道了一种与两个噻二唑融合的四氮杂五苯并苯二酮的合成和表征。这个由七个稠环组成的线性导数显示出很低的LUMO能级(-4.46 eV)和低的HOMO-LUMO能隙(1.77 eV)。它的高溶解性由四个三异丙基硅基赋予，使得可以通过液体沉积方法制备空气稳定的场效应晶体管，其电子迁移率高达2.42X10(-3)cm(-3)V-1 S(-1)，而不需要任何器件优化。
The synthesis and characterization of a tetraazapentacene-quinone fused to two thiadiazoles is reported. This linear derivative constituting seven fused rings shows a very low LUMO level (-4.46 eV) and a low HOMO-LUMO gap (1.77 eV). Its high solubility, endowed by four triisopropylsilyl groups, allows the fabrication of air-stable field-effect transistors by liquid deposition methods that show electron mobilities up to 2.42 X 10(-3) cm(2) V-1 s(-1) without any device optimization.
