Solvatochromic covalent organic frameworks [PDF]

Nature Communications, 2018
Covalent organic frameworks (COFs) find increasing application as sensor material, but fast switching solvatochromism was not realized. Here the authors demonstrate that combination of electron-rich and -deficient building blocks leads to COFs which fast

Colloidal Covalent Organic Frameworks

ACS Central Science, 2017
Covalent organic frameworks (COFs) are two- or three-dimensional (2D or 3D) polymer networks with designed topology and chemical functionality, permanent porosity, and high surface areas. These features are potentially useful for a broad range of applications, including catalysis, optoelectronics, and energy storage devices.

Polyphosphonate covalent organic frameworks

Nature Communications
Herein, we report polyphosphonate covalent organic frameworks (COFs) constructed via P-O-P linkages. The materials are synthesized via a single-step condensation reaction of the charge-assisted hydrogen-bonded organic framework, which is constructed from

Topological Aspects of Certain Covalent Organic Frameworks and Metal Organic Frameworks

Journal of Function Spaces, 2022
Topological indices are numerical numbers assigned to molecular graphs and are expected to predict certain of its physical or chemical properties. Metal-organic frameworks (MOFs) are inorganic/organic porous crystalline materials with a regular array of ...

Reconstructed covalent organic frameworks [PDF]

Nature, 2022
AbstractCovalent organic frameworks (COFs) are distinguished from other organic polymers by their crystallinity1–3, but it remains challenging to obtain robust, highly crystalline COFs because the framework-forming reactions are poorly reversible4,5.

Hydrogen-bonding and π-π interaction promoted solution-processable covalent organic frameworks

Nature Communications, 2023
Covalent organic frameworks show great potential in gas adsorption/separation, biomedicine, device, sensing, and printing arenas. However, covalent organic frameworks are generally not dispersible in common solvents resulting in the poor processability ...
