| 英文摘要 | In order to modulate the optoelectronic properties of thiophene-based conjugated polymers, two novel conjugated polymers (P1 and P2) comprising dithieno [3,2-b:2',3'-d] phosphole oxides (DTPhos) and 2, 2'-bithiophene have been designed and synthesized by Stille polycondensation, and their thermal, electrochemical and photophysical properties were studied. Both polymers are thermally stable with decomposition temperature above 400 degrees C, and exhibit the absorption maxima of ca. 590 nm and the optical band gap of 1. 76 eV. The incorporation of DTPhos units into polythiophene backbone results in a 0. 15 eV reduction of optical bandgap. HOMO and LUMO energy levels of the polymers as measured by cyclic voltammetry are -5. 1 and -2. 9 eV,respectively. Thin-film transistors (TFT) and bulk heterojunction solar cells (BHJ-SC) were fabricated based on P1 and P2. The performance of the devices increased with an increase of the alkyl chain length in the DTPhos units. With a bottom gate and top contact TFT device structure, P2 exhibited the hole mobility up to 0. 0077 cm(2)V(-1)s(-1). Under AM 1. 5 G illumination (100 mW/cm(2)),BHJ-SC based on P2 displayed an open-circuit voltage of 0. 68 V, a short-circuit current of 7. 9 mA/cm(2), a fill factor of 52% and a power conversion efficiency of 2. 8%. These results imply that DTPhos unit is a potential building block for high-performance polymer semiconductors. |
