Room‐Temperature Synthesis of Covalent Organic Framework (COF‐LZU1) Nanobars in CO₂/Water Solvent

Abstract

The development of facile, rapid, low-energy, environmentally benign routes for the synthesis of covalent organic frameworks (COFs) is of great interest. This study concerns the utilization of water containing dissolved CO as a solvent for the room-temperature synthesis of COF. The as-synthesized particles, denoted COF-LZU1, combine advantages of good crystallinity, nanoscale size, and high surface area, which suggests promising application as a support for heterogeneous catalysts. Moreover, this versatile CO -assisted method is also applicable for the room-temperature synthesis of Cu-COF-LZU1. This method gives rise to new opportunities for fabricating COFs and COF-based materials with different compositions and structures.

Ultra-permeable polyamide membranes harvested by covalent organic framework nanofiber scaffolds: a two-in-one strategy

“…The possible reason for the formation of the fibrous morphology may be ascribed to a specific dissolution–recrystallization process in the presence of excess polar solvents,30 such as water. This phenomenon has also been observed in other studies 31,32. Furthermore, because of the presence of excessive inherent positively charged guanidinium units (Fig.…”

Microwave‐Assisted Synthesis of Covalent Organic Frameworks: A Review

“…COFs allow a predictable design over composition, topology, and porosity of the structure by simply varying the units involved. In this way, many COFs develop highly desirable properties such as a well‐defined porosity, large surface areas, low mass density, excellent hydrothermal stability, and wide functional variety [41] . But excellent properties are not only limited to those related with the backbone constituents, because COFs can be further functionalized postsynthetically [42] …”

[41] But excellent properties are not only limited to those related with the backbone constituents, because COFs can be further functionalized postsynthetically. [42] In general, COFs can be classified attending to two structural parameters: type and topology of formed bonds.…”

Towards the room-temperature synthesis of covalent organic frameworks: a mini-review

“…In the other work, COF nanobars were fabricated in CO 2 /water solvent [36]. The presented method proved a facile, rapid, low-energy, and environmentally benign routes for the synthesis of COFs.…”
