Embodiment 1

[0036] A preparation method of a halogen bond eutectic material (Spe2-IFB), comprising: placing 4-styrenepyridine and 1,3,5-trifluoro-2,4,6-triiodobenzene in a clean reagent bottle , and then add an organic solvent to dissolve 4-styrenepyridine and 1,3,5-trifluoro-2,4,6-triiodobenzene in the organic solvent to obtain a mixed solution. Drop the mixed solution on a clean substrate, and keep it in a fume hood for 45 minutes at 25°C in the dark to allow the organic solvent to volatilize slowly. After the organic solvent volatilizes, a halogen-bonded eutectic material is obtained. In total, the ratio of 4-styrenepyridine to 1,3,5-trifluoro-2,4,6-triiodobenzene was 2:1. The substrate is glass, and the organic solvent is acetonitrile. The ratio of the parts by volume of the organic solvent to the parts by volume of the substance of 4-styrenepyridine is 5:10 -4 , the unit of parts by volume is milliliter (mL), and the unit of parts by volume is mole (mol).

Abstract

The invention discloses a halogen bond eutectic material, and a preparation method and application thereof. The preparation method comprises: dissolving a first component material and a second component material in an organic solvent to obtain a mixed solution, adding the mixed solution to a substrate in a dropwise manner, and standing for 10-60 min in a dark place to volatilize the organic solvent so as to obtain the halogen bond eutectic material. According to the invention, a simple, short-time-period and low-cost solvent volatilization method is adopted, a plurality of halogen bond eutectic materials with a molar ratio of 2:1 or 1:1 are obtained, and the yield of the growth preparation process is 100% completely.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric functional crystal materials, and in particular relates to a halogen bond eutectic material and its preparation method and application. Background technique [0002] Molecular eutectic is a special single crystal material formed by supramolecular self-assembly and crystallization of two or more organic compounds in a certain stoichiometric ratio. Scientists can chemically synthesize or rationally screen the constituent materials of the co-crystal, and then regulate the force between molecules in the co-crystal to realize the design and preparation of the multifunctional co-crystal. For example, Zhu Daoben and others from the Institute of Chemistry, Chinese Academy of Sciences discovered bipolar charge transport characteristics with both holes and electrons in the large π-fused ring system eutectic. "Strategy has obtained high carrier mobility and high luminous efficiency eutectic at...
