Abstract

The invention discloses a preparation method of a phenazine-connecting two-dimensional covalent organic framework material of a novel structure. The synthesized phenazine-connecting two-dimensional covalent organic framework material of the novel structure has a highly planar rigid structure in a graphene-like single layer, and is also highly conjugated between layers. A synthesis method is a solvothermal method and is easy and safe to operate, the reaction is a molecular level reaction, and the synthesized product is more ordered and more stable. According to the method, triphenylene-2,3,6,7,10,11-hexaaminotriphenylene and hexaketocyclohexane octahydrate serve as raw materials, 1,4-dioxane and 1,3,5-mesitylene serve as organic solvents, and the phenazine-connecting two-dimensional covalent organic framework material of the novel structure is successfully prepared through the solvothermal method under the condition that acetic acid is used for adjusting the acid environment.

Description

technical field [0001] The invention relates to the preparation of a novel structure of a phenazine-linked two-dimensional covalent organic framework material. Background technique [0002] The design, preparation and research of the relationship between structure and performance of new materials have always been the frontier fields of materials science, chemistry and physics. Since its discovery, graphene has shown potential application prospects in the field of optoelectronics due to its single-atom thickness and unique two-dimensional planar structure, semi-metallic energy band structure and high carrier mobility. Semiconductor-based new electronic materials in the post-Moore's Law era. However, the zero bandgap of graphene limits its practical application. Designing and preparing new graphene-like materials with adjustable bandgap has become another hot spot in materials science, chemistry, physics and other disciplines in recent years. Two-dimensional covalent organic...
