Embodiment 1

[0037] A kind of soluble graphene nanoribbon, its synthetic method comprises the steps:

[0038] (1) Synthesis of 4-(2-ethylhexyloxy)phenylboronic acid:

[0039] The synthetic route is shown in the following formula:

[0040]

[0041] The specific operation is:

[0042] Take activated magnesium powder (100mmol, 2.4g), 4-(2-ethylhexyloxy) bromobenzene (100mmol, 28.5g) in a 500mL three-necked bottle, change argon three times, inject tetrahydrofuran (THF) 100mL, heat Reflux for 3 hours (until the magnesium powder disappears completely), cool to room temperature, add THF150mL, cool down to -80°C, add 24mL trimethyl borate at one time, react at -65°C for 3 hours, and react overnight without removing the thermos; the next day Add 20 mL of concentrated sulfuric acid and 100 mL of water dropwise into ice, stir for half an hour, separate layers, add water, extract with ethyl acetate, wash with saturated brine, and dry over magnesium sulfate; A 25 cm column was filled with silica ...

Abstract

The invention belongs to the technical field of functional materials and discloses a soluble graphene nanoribbon as well as a synthetic method and an application thereof. The synthetic method comprises the steps that 2,6-dibromo-4-nitroaniline and alkyl / alkoxy arylboronic acid have a Suzuki coupling reaction, 2,6-bis(4-alkyl / alkoxy benzene)-4-nitroaniline is obtained and reduced, 2,6-bis(4-alkyl / alkoxy benzene)-1,4-phenylenediamine is obtained and has halogenation, 2,6-bis(4-alkyl / alkoxy benzene)-1,4-dibromo / iodobenzene is obtained and has an Miyaura borylation reaction, and 2,6-bis(4-alkyl / alkoxy benzene)-4-boronic acid pinacol ester-1-bromo / iodobenzene is obtained; then a poly-para-phenylene derivative is generated through the Suzuki coupling reaction, and a product is obtained through oxidative dehydrogenation. The soluble graphene nanoribbon can be applied to the fields of field effect transistors, photovoltaic cells, non-linear optics and sensing.

Description

technical field [0001] The invention belongs to the technical field of functional materials and relates to a graphene nanobelt, in particular to a soluble graphene nanobelt and its synthesis method and application. Background technique [0002] Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is a hexagonal planar film composed of carbon atoms with sp2 hybrid orbitals. The thickness is only one carbon atom thick. The thinnest but also the hardest nanomaterial in the world. Graphene has extremely high thermal conductivity (5300W / m K), especially its electron mobility exceeds 15000cm at room temperature 2 / V·s, which is higher than that of carbon nanotubes or silicon crystals, and the resistivity is only about 10 -6 Ω cm, lower than copper or silver, is the material with the smallest resistivity in the world. Graphene's high conductivity and high mobility are derived from its super-large-area conjugated structure, which is expected...
