Embodiment 1

[0043] Embodiment 1: Nano self-assembly experiment of SFX-2-Cz molecule

[0044]First prepare a surfactant P123 aqueous solution with a concentration of 2 mg / mL. Prepare a 10mL sample bottle, put it into the magnet, add 5mL of 2mg / mL surfactant P123 aqueous solution, and set aside. Dissolve 0.1 mg of SFX-2-Cz molecule completely in 1 mL of tetrahydrofuran, and use a pipette gun to inject all the tetrahydrofuran mixture dissolved in the target molecule into the aqueous solution sample bottle containing surfactant P123 under the condition of uniform rotation of the magneton medium, stir for 4-8 minutes. During this process, white flocs can be seen with the naked eye, and after the stirring is completed, it becomes a milky white liquid. Take out the magnet, let the mixed solution stand at room temperature for about 30 hours, centrifuge at a speed of 17000r / min, and wash with ultrapure water for 4 to 5 times until the surfactant is completely removed. Take a drop of about 10 μL...

Abstract

The invention discloses an organic nanomaterial based on spirofluorene-xanthrene mono-substituted carbazole, a preparation method and application thereof. The organic nanomaterial is prepared by adding a surfactant to the compound SFX-2-Cz, SFX-3'-Cz, or SFX-2'-Cz. The structural formulas of the compounds SFX-2-Cz, SFX-3'-Cz and SFX-2'-Cz are shown as the specification. The nano-structure preparedaccording to the invention has the advantages of regular structural morphology and uniform size, realizes controllable preparation of one-dimensional to two-dimensional organic nanostructures. Corresponding photoluminescence characterization means proves that the optical properties of the organic nanomaterial are strongly dependent on the molecular structure and molecular aggregation mode. The invention shows the application potential of the organic semiconductor materials in future optoelectronic devices.

Description

technical field [0001] The invention belongs to the field of nanotechnology, and in particular relates to an organic nano material based on spirofluorene xanthene (SFX) monosubstituted carbazole (Cz) and a preparation method and application thereof. Background technique [0002] Organic semiconductors have attracted great interest as key components of future optoelectronic devices. Their electronic, excitonic and photonic properties, including anisotropic carrier transport, optical waveguiding and delayed fluorescence, strongly depend on the condensed state of organic molecules, that is, molecular arrangement, crystal structure, morphology and size. For organic field-effect transistor (OFET) applications, precise control of molecular packing modes such as 1D π-stacking, 2D herringbone / brick-stacking, and stacked crystals in order to achieve higher charge carrier mobility in its specific orientation Grid is extremely important. For fluorescence emission, the face-to-face st...
