Design and Synthesis of Polyimide Covalent Organic Frameworks

Abstract

As a subseries of the covalent organic framework (COF) material family, polyimide-based covalent organic framework (PI-COF) material, which has the advantages of high stability of polyimide, high specific surface area, and controllable pores of COF material, is expected to be a new type of porous material with potential applications. Although the development of PI-COF is in the early stages during the past decade, it has attracted extensive attention and is widely used in heterogeneous catalysis, gas separation, and storage fields. Therefore, this review is aiming to give a comprehensive understanding of the recent progress of PI-COFs. This article summarizes the progress of PI-COF from three aspects: controllable structure design, synthesis method, and application. First of all, under the guidance of network chemical design principles, the topology type of PI-COF and the size and shape of the formed pores are summarized in terms of different organic monomers. Then the five synthetic strategies for the synthesis of PI-COF are analyzed. Finally, the applications of PI-COF in adsorption and separation, drug delivery, solar-to-electrochemical energy storage, photocatalysis, and electrocatalyst are introduced.

Crosslinked porous polyimides: structure, properties and applications

“…The expected trend is that crystalline (COF) porous pPIs will have higher surface areas than their amorphous counterparts (for a comprehensive review on crystalline polyimides see Zhang et al 15 ) and is indeed apparent in the highest surface area reported for the crystalline pPI synthesised by Fang et al 9 at 2403 m 2 g -1 . This trend is observed where similar pPIs were synthesised with either amorphous or crystalline properties, with the crystalline materials having higher surface areas owing to an increase in uniformity of the pores (see Table 3).…”

Porous framework-based hybrid materials for solar-to-chemical energy conversion: from powder photocatalysts to photoelectrodes

“…54 Because of their large surface area and micro-/mesoporous structure, they can provide versatile platforms for separation, 55 sensing, 56 and ( photo)catalysis. 57 There are many comprehensive review papers on the design and synthesis of MOFs 58,59 and COFs 60,61 for various applications.…”

Progress in Aromatic Polyimide Films for Electronic Applications: Preparation, Structure and Properties

“…In recent years, there have been many publications on polyimide materials [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. In this review, the representative progress, mainly in our laboratory, in advanced polyimide films, will be described, especially focusing on the structure and properties for electronic applications.…”
