Example

[0039] Example 1 - Example 5: Preparation method of TCN-SFX fractal crystals

[0040] Weigh 1 ml of TCN-SFX sample in 10 ml of TCN-SFX samples, 1 ml of tetrahydrofuran is sufficiently dissolved, configured to concentrate in TCN-SFX tetrahydrofuran solution, and rapidly injecting Tcn-SFX tetrahydrofuran solution to vigorously stirred 5 ml SDS In the sample bottle of the aqueous solution, the lid is stirred for 5 minutes, and the magneton is removed, and the suspension of the fractal crystal is obtained after 40 ° C, and the solvent can be obtained to obtain the fractal crystal after the solvent is volatilized.

[0041]Example 1 - Example 5, the difference between the different embodiments only is that the sample concentration and the preparation ambient temperature, the remaining parameters, and the steps are all identical, and the sample concentration and preparation environment setting conditions of each embodiment are described in the following table:

Abstract

The invention discloses a fractal crystal of cyano-substituted spirocyclic aromatic hydrocarbon molecules, and a preparation method and application of the fractal crystal. The fractal crystal is formed by stacking the cyano-substituted spirocyclic aromatic hydrocarbon molecules in a cross-shaped manner and orderly arranging the cyano-substituted spirocyclic aromatic hydrocarbon molecules. The SAHs are substituted by supramolecular action groups and play a role of in-place resistance, symmetrical and relatively strong supramolecular action force is introduced by the symmetrically substituted supramolecular action groups, and branch growth and tip rupture of a SAHs crystal are realized through concentration and temperature regulation and control, so the fractal crystal is formed; and the fractal crystal can be widely applied to photoelectric devices as a photoelectric material and has fluorescent luminescence stability.

Description

technical field [0001] The invention belongs to the technical field of organic micro-nano crystal materials, and in particular relates to a cyano-substituted spiro aromatic molecular fractal crystal and a preparation method and application thereof. Background technique [0002] For billions of years, nature has exhibited countless simple and complex chemical structures with fractal shapes, including snowflakes, leaves, branches, coastlines, etc. Among them, snowflake crystal, as the most common crystal structure with regular hexagonal fractal, has been widely reported. Fractal structures are a much-needed important milestone in the history of materials engineering, not only filling the missing link between integer-dimensional structures, but also providing excellent models for structural studies. Fractal crystal materials are composed of long-period ordered units with unique morphologies, which have great advantages in crystal engineering and open up new research fields in ...
