Problems solved by technology

These supramolecular systems exhibit short-range order, but lack the ability to further self-assemble into three-dimensional structures, so they can only be applied to basic research at this molecular level

Embodiment 1

[0028] Preparation of electroluminescent device A

[0029] A is hydroxyl-terminated polyfluorene PFOH:

[0030]

[0031] B is polymethacrylic acid;

[0032] A and B are dissolved together in tetrahydrofuran (the weight ratio of A and B is 1:11) to prepare a solution. A and B interact through hydrogen bonds to form a macromolecular complex paired between segments in tetrahydrofuran. Add the precipitant water of A while ultrasonically oscillating to generate nanoparticles with a core-shell structure. At this time, when the sample is irradiated with laser light, obvious diffuse reflection can be found, that is, the Tyndall phenomenon.

[0033] The AB assembly was spin-coated to prepare a thin film, and its photoluminescence spectrum was measured. According to the preparation method of the electroluminescent device described above, ITO glass is used as the conductive layer, and the hole transport material is vacuum evaporated on the conductive layer, and then the luminescent...

Abstract

The invention discloses an electroluminescent molecular self-assembly body and an application thereof. A and B form a macromolecular complex paired between chain segments in a common solvent through non-covalent bond interaction, such as hydrogen bond interaction or ionic interaction. Nano particles with a nuclear shell structure are produced by adding a precipitator of A or B. After non-covalent bonds are self-assembled in the solution, the spectral character of the self-assembly body, especially the spectral character in a thin solid film, is detected. An electroluminescent device is produced by using a conventional spin coating method.

Description

technical field [0001] The invention belongs to the technical field of photoelectric materials, and in particular relates to a preparation method of an electroluminescent device. Background technique [0002] In recent years, as conjugated systems have gradually begun to be applied in electronic devices, the dream of molecular electronics based on conjugated systems is gradually becoming a reality. At the same time, nanoscience and nanotechnology have logically merged, and academia and industry have been closely integrated for this purpose. The results of device physics guide the synthesis of new molecules in an unpredictable way, and in turn device performance can only be improved based on progress in the synthesis of new materials. Therefore, the two key factors determining the performance of conjugated polymer electronic devices are the conjugated polymer chemical structure and its nanostructure in the solid state. The physical properties of independent polymer chains a...
