| 英文摘要 | A pair of analogous polymers based on diketopyrrolopyrrole (DPP) and dithienopyrrole (DTP) were designed to have a small structural difference in the side chain, PDDPDTP-C with an alkyl chain and PDPPDTP-P with an alkylphenyl chain. The two polymers have the same absorption and band gap but show different hole mobility, molecular stacking and film morphology. As a result, the PDPPDTP-P photodetector has a much higher responsivity (291 mA W-1 at 900 nm at -0.1 V) than the one based on PDDPDTP-C (36 mA W-1), and exhibits a specific detectivity over 1012 Jones in the spectral region of 350-950 nm. |
