Abstract

The invention belongs to the field of organic semiconductor materials, and particularly relates to a BFD microwire and a preparation method and application thereof. The preparation method comprises the following steps: dissolving BFD in a good solvent, adding a poor solvent, mixing, and volatilizing to obtain the BFD microwire. The BFD organic polymorph prepared by adopting a solvent evaporation method and the alloy microwire formed by self-assembly of the BFD organic polymorph have the advantages of being simple and rapid in preparation process, relatively high in yield, short in time consumption, low in energy consumption, mild in reaction temperature and the like, and are beneficial to industrial production and application in the field of multicolor display.

Description

technical field [0001] The invention belongs to the field of organic semiconductor materials, and in particular relates to a BFD micro-wire and a preparation method and application thereof. Background technique [0002] The luminescent properties of organic semiconductor materials are key functions for their lighting and display applications. Tunable emission colors have been of constant interest in fundamental research and potential optoelectronic applications in the fields of full-color displays, smart paints / paints, information encryption, bioimaging, etc. Upconversion-type micro-nano crystals have successfully constructed a true three-dimensional full-color display system with well-tuned emission color (Nat. Nanotechnol. 2015, 10, 237-242). Compared with inorganic materials, organic semiconductors are considered as the most promising candidates for tunable emission colors due to their tunable molecular structures and tunable optical / electronic properties (Nat.Photonics ...
