Chemical Vapor Deposition Synthesis and Terahertz Photoconductivity of Low-Band-Gap N = 9 Armchair Graphene Nanoribbons

Recent advances in bottom-up synthesis of atomically defined graphene nanoribbons (GNRs) with various microstructures and properties have demonstrated their promise in electronic and optoelectronic devices. Here we synthesized N = 9 armchair graphene nanoribbons (9-AGNRs) with a low optical band gap of ～1.0 eV and extended absorption into the infrared range by an efficient chemical vapor deposition process. Time-resolved terahertz spectroscopy was employed to characterize the photoconductivity in 9-AGNRs and revealed their high intrinsic charge-carrier mobility of approximately 350 cm2·V-1·s-1

ORTHO-TERPHENYLS FOR THE PREPARATION OF GRAPHENE NANORIBBONS

The present invention concerns ortho-Terphenyls of general formula (I); wherein R1, R2, R3 and R4 are independently selected from the group consisting of H; CN; NO2; and saturated, unsaturated or aromatic C1-C40 hydrocarbon residues, which can be substituted 1 - to 5- fold with F, CI, OH, NH2, CN and/or NO2, and wherein one or more -CH2-groups can be replaced by -O-, -NH-, -S-, -C(=O)O-, -OC(=O)- and/or -C(=O)-; and X and Y are the same or different, and selected from the group consisting of F, CI, Br, I, and OTf (trifluoromethanesulfonate); and their use for the preparation of graphene nanoribbons as well as a process for the preparation of graphene nanoribbons from said ortho-Terphenyls.
