Abstract

The invention discloses a preparation method of a two-dimensional carbon-rich material rich in carbonyl (double bonds of carbon to oxygen), thioketone (double bonds of carbon to sulphur) and selenone (double bonds of carbon to selenium) functional groups and application of the two-dimensional carbon-rich material, and belongs to the field of application of the material. The material consists of conjugated six-membered rings containing the carbonyl, thioketone and selenone functional groups and acetylenic bonds; 1 and 4 positions of each conjugated six-membered ring are substituted by the carbonyl, thioketone and selenone functional groups; 2, 3, 5 and 6 positions of each conjugated six-membered ring are connected with the acetylenic bonds; and two acetylenic bonds exist between each two adjacent six-membered rings to form a highly conjugated two-dimensional planar framework structure. The preparation method mainly comprises the following steps: taking materials such as tetra-alkynyl substituted p-benzoquinone as a polymeric precursor; carrying out alkyne coupled reaction in a dioxane solution so as to obtain the carbon-rich two-dimensional material with the highly conjugated structure. Owing to introduction of carbonyl, double bonds of carbon to sulphur and double bonds of carbon to selenium, an ion transport channel and an energy storage activity points of the two-dimensional carbon-rich material are improved effectively, and therefore, the two-dimensional carbon-rich material has good application prospect in the field of energy storage devices.

Description

technical field [0001] The invention belongs to the field of material application research, and specifically relates to a novel two-dimensional carbon-rich material rich in carbonyl, thione and selenone sulfone functional groups and a preparation method thereof. Background technique [0002] Carbon is a very common element, which widely exists in various forms in the earth's crust, atmosphere and living organisms. In the past 20 years, scientists have been committed to developing new methods to synthesize new carbon allotropes and explore their new properties. New carbon allotropes such as fullerenes, carbon nanotubes and graphene have been discovered successively. And it has become the frontier and hot spot of international academic research, forming an independent research field of interdisciplinary science. In recent years, due to the advantages of large specific surface area, good thermal and electrical conductivity, and excellent chemical stability, two-dimensional c...
