Two-dimensional amine and hydroxy functionalized fused aromatic covalent organic framework [PDF]
, 2020 Ordered two-dimensional covalent organic frameworks (COFs) have generally been synthesized using reversible reactions. It has been difficult to synthesize a similar degree of ordered COFs using irreversible reactions.

Vinylene-Linked Covalent Organic Frameworks by Base-Catalyzed Aldol Condensation [PDF]
, 2019 Two 2D covalent organic frameworks (COFs) linked by vinylene (−CH=CH−) groups (V‐COF‐1 and V‐COF‐2) are synthesized by exploiting the electron deficient nature of the aromatic s‐triazine unit of C3‐symmetric 2,4,6‐trimethyl‐s‐triazine (TMT).

Thiophene-based covalent organic frameworks [PDF]
Proceedings of the National Academy of Sciences, 2013 We report the synthesis and characterization of covalent organic frameworks (COFs) incorporating thiophene-based building blocks. We show that these are amenable to reticular synthesis, and that bent ditopic monomers, such as 2,5-thiophenediboronic acid, are defect-prone building blocks that are susceptible to synthetic variations during ...

Hybrid Porous Crystalline Materials from Metal Organic Frameworks and Covalent Organic Frameworks
Advanced Science, 2021 Two frontier crystalline porous framework materials, namely, metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs), have been widely explored owing to their outstanding physicochemical properties. While each type of framework has its own

Covalent organic frameworks and organic cage structures [PDF]
, 2017 The last 20 years have seen an enormous interest in research on the topic of crystalline porous framework materials, especially metal–organic frameworks (MOFs). MOFs exploit reversible metal–coordination chemistry to create extended, crystalline solids.1
