Development of an Organic Electrochemical Transistor with the Semiconducting Graphene Oxide Nanoribbons

The synthesis of controllable nanoporous graphene oxide nanoribbons and their organic electrochemical transistors will be investigated in this study. From experimental viewpoint, we plan to use the patented microwave-assisted process to fabricate graphene nanoribbons from multiwalled carbon nanotubes. Unlike the inter-ribbon nanopores in literature (Science 2018, 360, 199.), we will further prepare the graphene nanoribbons with tunable intra-ribbon nanopore structures, C/O ratios, and unzipping levels. After the analyses of all kinds of nanoribbons, the coworkers at Ming Chi University of Technology will help us develop the nanoporous graphene oxide nanoribbon organic electrochemical transistors. In the future, TKU collaborators will use our nanoribbons for the operando X-ray spectroscopy experiments at NSRRC. From the theoretical viewpoint, the coworkers at NTU and we will calculate the adsorption and charge transfer of biomolecules using density functional theory. Besides our experiences in carbon nanotube, graphene and graphene nanoribbon in early publications, (Biosens. Bioelectron. 2015, 67, 327.; Biosens. Bioelectron. 2015, 67, 431.; Nano Energy 2016, 27, 114.; Angew. Chem. Int. Ed. 2017, 56(52), 16498.; Carbon 2018, 126, 328.) we already have some results which can prove this proposal is doable as well as valuable. It is believed that we must be able to contribute to the development of nanoribbon-based organic electrochemical transistors with significant research achievement and publications.
