Problems solved by technology

However, the imine group is not stable and is easily hydrolyzed, resulting in low weather resistance of the material
In addition, the carrier mobility of conjugated polymers containing imine groups is generally not high, which also affects their applications.

Abstract

The invention discloses a porphyrin-containing two-dimensional conjugated polymer and its preparation method and application. The general formula of the structural unit of the porphyrin-containing two-dimensional conjugated polymer is: the porphyrin-containing two-dimensional The preparation method of the conjugated polymer is as follows: under the protection of an inert gas, the compound of formula (1), the compound of formula (2) and the catalyst are dissolved in an organic solvent immiscible with water to obtain an organic phase, and the alkali is dissolved in The water phase is obtained in water, the organic phase and the water phase are placed in the same container to form an interface, and they are left to stand at 0-100°C for 1-90 days, and the porphyrin-containing two-dimensional conjugated polymerization is obtained at the interface The general structural formula of the compound of formula (1) is: the general structural formula of the compound of formula (2) is: the two-dimensional conjugated polymer has a large lateral scale, high order and field-effect mobility High, can be used as a channel material for the preparation of field effect transistors. The preparation method of the two-dimensional conjugated polymer has mild conditions and simple operation.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a porphyrin-containing two-dimensional conjugated polymer and its preparation method and application. Background technique [0002] Two-dimensional conjugated polymer materials are a kind of planar large conjugated polymer film materials that can exist independently and stably, and have an ordered internal structure. Since the discovery of graphene in 2004, this type of material has gained widespread interest from the scientific and industrial communities. This type of material has three important characteristics: large conjugation, porosity and huge specific surface area. The large conjugation makes this type of material have special optical and electrical properties, which can be used in transistors, photocells and various electrochemical-related devices; the porosity and huge specific surface area make this type of material can be used to build important interfa...
