Witryna1 maj 2024 · Here we report the synthesis of picolinaldehyde-derived imine-linked COFs that can be transformed into imidazopyridinium-linked COFs (IP-COFs) with a Lieb-like lattice. IP-COFs serve as precursors to ambivalent N-heterocyclic carbenes that can dissociate disulfide bonds to form carbon–sulfur bonds. IP-COFs exhibit a vastly …
WitrynaThe functionalized covalent organic framework materials play an important role in catalytic application. A convenient tactic is developed to design and synthesize an imine-linked covalent organic frameworks (COFs) material (COF-PD) with abundant nitrogen atoms, which can provide coordination active site and facilitate the incorporation of … Witryna8 lut 2024 · Covalent organic frameworks (COFs) are a class of porous crystalline polymers that can be obtained by linking the organic building blocks via covalent bond into two- dimensional(2D) layered eclipsed structure or three-dimensional (3D) networks [1–3].Since COFs were reported by Yaghi’s group in 2005 [], they have been shown …
