摘要:
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.
