Abstract

The invention discloses an azafluorene micromolecule based butterfly organic nanocrystal material and a preparation method and an application of the material. The azafluorene micromolecule based butterfly organic nanocrystal material has an asymmetric double-faced butterfly multidimensional micron structure, wherein one side is quincuncial, and the other side is butterfly-shaped. Controllable preparation of a pure organic micromolecule nanomaterial in the field of a multidimensional structure is achieved. A deep relationship between a growth mechanism and a morphology of the organic nanomaterial and a molecular structure is confirmed by corresponding characterization means such as dynamic growth process and monocrystal analysis. In addition, excellent lead performance of the structure is verified based on a conductive atomic force microscope platform. An application potential of the organic semiconductor material in future photoelectronic devices is shown.

Description

technical field

[0001] The invention belongs to the field of nanotechnology, and in particular relates to a butterfly-shaped organic nano crystal material based on pure organic small molecules and its preparation method and application. Background technique

[0002] In recent years, micro-nanocrystalline semiconductors with multidimensional and complex morphologies have been favored by more and more researchers, mainly because this type of material has a rich surface microenvironment, and the surface effects brought about by it are important in catalysis and energy. Areas such as storage have unlimited application potential. In the past few decades, nanocrystals with multidimensional and complex shapes were mainly prepared from inorganic materials. Recently, some organic materials, such as biomacromolecules and organometallic complexes, can also obtain complex multi-dimensional micro-nano structures through bottom-up self-assembly. However, so far, the synthesis of nanocry...

[0041] Embodiment 1: Nano self-assembly experiment of butterfly-shaped organic nanocrystals

[0042] Firstly, an aqueous solution of polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer P123 with a concentration of 1 mg / mL was prepared. Prepare a 10mL sample bottle, put it into a magnet, add 5mL of a polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer P123 aqueous solution with a concentration of 1mg / mL, and set aside.

[0043] 0.1 mg of TPA (PDAF) 3 Molecule is completely dissolved in 1mL tetrahydrofuran, under the condition of uniform rotation of the magneton, use a pipette gun to dissolve TPA(PDAF) 3The tetrahydrofuran solution of the molecule is all injected into the sample bottle containing the aqueous solution of polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer P123 within 1-2 seconds at one time, and stirred for 4-8 minutes. During this process, white flocs can be seen with the naked eye, and...
