Jul 23, 2014 · In this study, we design and synthesize a series of large-pore crystalline PI COFs (termed PI-COFs) by achieving reversible imidization. These crystalline porous materials feature large pores...

Oct 14, 2020 · 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.

Jun 22, 2015 · Three-dimensional porous crystalline polyimide covalent organic frameworks (termed PI-COFs) have been synthesized. These PI-COFs feature non- or interpenetrated structures that can be obtained by choosing tetrahedral building units of different sizes.

May 23, 2022 · In this study, polyimide COFs (PI-COFs) are synthesized through the condensation reaction of pyromellitic dianhydride (PMDA) with tris(4-aminophenyl) amine (TAPA) and then doped in the TiO 2 photoelectrode of a dye-sensitized solar cell (DSSC) to co-work with N719 dye to explore their functionality. As a benchmark, the pristine DSSC without the ...

Dec 11, 2023 · Here, we report a widely applicable strategy to construct solution-processable COFs by breaking the intrinsic Van der Waals and π-π interactions in COFs through using commercially available...

Jun 1, 2021 · Covalent organic frameworks (COFs) are the emerging type of organic crystalline porous materials, prepared through reticular chemistry with building blocks featuring light elements (such as C, H, O, N, or B atoms), and connected through the covalent bond and extended into two or three dimensions.

Dec 13, 2022 · Polyimide covalent organic framework (PI-COF) materials that can realize intrinsic redox reactions by changing the charge state of their electroactive sites are considered as emerging electrode materials for rechargeable devices.

Dec 20, 2024 · In this study, we report the synthesis of two novel polyimide covalent organic frameworks (PI-COFs), COF-JLU85 and COF-JLU86, by combining truxenone-based triamine and linear acid anhydride through polymerization.

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.

Jul 8, 2015 · Three-dimensional porous crystalline polyimide covalent organic frameworks (termed PI-COFs) have been synthesized. These PI-COFs feature non- or interpenetrated structures that can be obtained by choosing tetrahedral building units of different sizes.
