Embodiment 1

[0028] Mix 6.88 mg of 2,5-methoxy-4,4'-bipyridylpolystyrene (DPEpe) and 8.02 mg of 1,4-diiodotetrafluorobenzene (F 4 DIB) was added to 4 mL of dichloromethane and sonicated for 3 min to obtain DPEpe-F 4 DIB dichloromethane stock solution. Take 1mL of the stock solution and add it to 1mL of ethanol to shake well, and then drop it on the substrate. After the organic solvent evaporates to dryness, organic eutectic microcrystals with strong green fluorescence are obtained. By powder X-ray diffraction (XRD, image 3 ), scanning electron microscopy (SEM, Figure 4 ), atomic force microscope (AFM, Figure 5 ), transmission electron microscopy (TEM), and selected electron diffraction (SAED) ( Image 6 ) and fluorescence microscopy (FM, Figure 7 ) test means to characterize the organic eutectic micro-crystals. The comprehensive results show that the halogen-bonded eutectic organic micro-crystal is a two-dimensional single-crystal micro-sheet with a length of 50-70 microns, a wid...

Abstract

The invention provides a two-dimensional eutectic organic single crystal micro crystal, a preparation method and application thereof. The method comprises the following preparation steps: selecting pyridine nitrogen-containing oligostyrene-based organic molecules as halogen bond donor molecules, and selecting iodobenzene organic molecules as halogen bond acceptor molecules, adding the halogen bonddonor molecules and the halogen bond acceptor molecules into a good organic solvent and sonicating for several minutes to prepare an organic solvent stock solution of the halogen bond donor moleculesand the halogen bond acceptor molecules; at room temperature, adding the organic solvent stock solution of the halogen bond donor molecules and the halogen bond acceptor molecules into a poor organicsolvent to shake uniformly, then dripping on a substrate, and drying the organic solvent through volatilization to obtain a two-dimensional organic eutectic micro nanostructure material. The two-dimensional eutectic organic single crystal micro crystal can be supposed to be used for preparing an optical logic device for multichannel input and output. The invention provides a new approach for realizing controllable preparation of the two-dimensional organic micro crystal, and the organic crystal can realize asymmetric photon transmission, thereby realizing the optical logic device with multiple input/output channels which take a two-dimensional organic micro nanostructure crystal as a carrier.

Description

technical field [0001] The invention belongs to the application of organic crystal optoelectronic devices, in particular to a two-dimensional eutectic organic single crystal micron crystal, a preparation method and an application thereof. Background technique [0002] Two-dimensional organic crystals have multidirectional photon transmission, making them more suitable for applications in chip-scale planar optical systems, whispering gallery mode resonators (organic crystal lasers), and directionally steerable waveguides. Professor Fu Hongbin's team used two-dimensional organic stilbene single crystal hexagonal microdisks as whispering gallery mode resonators to simultaneously realize multi-mode and single-mode lasers. However, for single-component materials, very limited organic molecules have 2D self-assembly properties, which severely restricts the development of 2D organic optoelectronics. Therefore, designing and preparing organic functionalized motifs with 2D self-asse...
