Abstract

The invention discloses an azafluorene-based small molecule butterfly-shaped organic nanocrystal material and its preparation method and application. The azafluorene-based small-molecule butterfly-shaped organic nanocrystal material has an asymmetric double-sided butterfly-shaped multi-dimensional micron structure , one side is plum-shaped and the other is butterfly-shaped. The invention realizes the controllable preparation of pure organic small molecule nanometer material in the field of multi-dimensional structure. Through the corresponding dynamic growth process and single crystal analysis and other characterization methods, the growth mechanism of this organic nanomaterial and the deep relationship between the morphology and molecular structure were confirmed. In addition, the excellent wire performance of the structure was verified based on the conductive atomic force microscopy platform. The application potential of such organic semiconductor materials in future optoelectronic devices is demonstrated.

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...
