Two-dimensional eutectic organic single crystal micro crystal, preparation method and application thereof

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...
