Upon evaluating both polymers as active conjugated materials in light-emitting electrochemical cells, they both exhibit emission under efficient electron/hole doping conditions.]]> Wed 01 May 2024 16:09:55 AEST ]]> Tuning the Charge Carrier Polarity of Organic Transistors by Varying the Electron Affinity of the Flanked Units in Diketopyrrolopyrrole-Based Copolymers https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41142 2 V−1 s−1, respectively. Most intriguingly, a clear charge-carrier-polarity change is observed when the devices are measured under vacuum. The pDPF-DTF2 polymer exhibits a balanced ambipolar performance with the µh/µe ratio of 1.9, whereas pDPSe-DTF2 exhibits p-type dominated charge carrier transport properties with the µh/µe ratio of 26.7. Such a charge carrier transport change is due to the strong electron-donating nature of the selenophene. Furthermore, pDPPy-DTF2 with electron-withdrawing pyridine flanking units demonstrates unipolar n-type charge transport properties with an electron mobility as high as 0.20 cm2 V−1 s−1. Overall, this study demonstrates a simple yet effective approach to switch the charge carrier polarity in transistors by varying the electron affinity of flanking groups of the diketopyrrolopyrrole unit.]]> Wed 01 May 2024 15:47:56 AEST ]]> Diketopyrrolopyrrole based organic semiconductors with different numbers of thiophene units: Symmetry tuning effect on electronic devices https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47661 Tue 24 Jan 2023 15:33:52 AEDT ]]> Tin oxide for optoelectronic, photovoltaic and energy storage devices: A review https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47081 Tue 13 Dec 2022 16:28:37 AEDT ]]> Naphthalene flanked diketopyrrolopyrrole based organic semiconductors for high performance organic field effect transistors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43296 Thu 15 Sep 2022 12:51:31 AEST ]]> Diketopyrrolopyrrole-Based Dual-Acceptor Copolymers to Realize Tunable Charge Carrier Polarity of Organic Field-Effect Transistors and High-Performance Nonvolatile Ambipolar Flash Memories https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49713 500 programming and erasing cycles.
