| 英文摘要 | In order to demonstrate the influence of structural fine-tuning on bandgap and semiconductor performance of pi-conjugated polymer materials, three new diketopyrrolopyrrole (DPP) based copolymers P1, P2 and P3 with monomers, i.e., 2-phenylpyridine, 2-(thiophen-2-yl)pyridine and 2-(thiophen-2-yl)thiazole, respectively, have been synthesized using a typical Suzuki cross-coupling polycondensation. The DFT calculations demonstrate that polymer P3 displays high backbone coplanarity in comparison to polymers P1 and P2. Absorption spectra results reveal that P3 exhibits a remarkable red-shifted absorption profile, narrow band gap and broad absorption. The thin film FET measurements show that P3 possesses the highest hole mobility (mu(h)) up to 1.25 cm(2) V-1 s(-1) and on/off (/(on/off)) ratio as high as 10(8). Those results demonstrate that the fine-tuning of the pi-conjugated backbone can significantly affect the band gaps and coplanarities, and ultimately improve the semiconducting performances. |
