英文摘要: Here, a conjugated polymer VTTPD based on thieno[3,4-c]pyrrole-4,6-dione (TPD) and dithiophene with vinyl as linker is synthesized and characterized. Electrochemical and optical studies indicate the LUMO and HOMO energies of the polymer are -3.70 and -5.39 eV. Theoretical calculation with density functional theory suggests that H-bonds are formed between the TPD carbonyl (O) and its neighboring vinyl (H) which benefit the planarity and -conjugation of the polymer backbone. Bottom contact bottom gate organic field effect transistor devices based on VTTPD are fabricated and examined in air. After annealing at 160 degrees C, the devices exhibit excellent performance of (h) = 0.4 cm(2) V-1 s(-1), I-on/off = 10(6), Vth within -10 V to -5 V. Thin film morphologies before and after the annealing process are also investigated with XRD and AFM.
