Synthesis, Properties, and OFET Characteristics of 5,5 '-Di(2-azulenyl)-2,2 '-bithiophene (DAzBT) and 2,5-Di(2-azulenyl)-thieno[3,2-b]thiophene (DAzTT)
[摘要]:Two azulene-based pi-conjugated systems, 5,5'-di(2-azulenyl)-2,2'-bithiophene and 2,5-di(2-azulenyl)-thieno[3,2-b]thiophene, were constructed via Suzuki-Miyaura cross-coupling reactions. The crystal structures of both revealed an edge-to-face orientation in a well-defined herringbone packing. The molecules stood nearly perpendicular to the substrate in the film form, with features of an organic field-effect transistor at hole mobilities of up to 5.0 x 10(-2) cm(2) V-1 s(-1).
