Product Overview

The concept of Covalent Organic Frameworks (COFs) materials was first proposed in 2005 by Yaghi et al., aiming to develop a new class of porous materials with highly ordered structures and specific functions. COF is a kind of crystalline organic porous polymer material with periodic structure formed by strong covalent bond of light elements (such as C, H, O, N, etc.). COF is derived from the polymerization of small organic molecules. In order to meet the requirements of high crystallinity of COF materials, COF needs to continuously complete the recombination of covalent bonds in the polymerization process to form a long-range ordered crystal structure. Depending on the type of reaction, the main reactions to produce COF are: boric acid polycondensation (boron-oxygen bond), C-C coupling reaction (carbon-carbon bond), Schiff base reaction (imine bond), cyano-autopolymerization (triazine bond) and aryl ether polymerization (carbon-oxygen bond) reaction. Among them, CFS containing reversible boro-oxygen bonds, imine bonds and triazine bonds are the most common and widely used. The common methods of COF synthesis include solvothermal method, microwave assisted solvothermal method, mechanical force method, ionic thermal method and room temperature solution synthesis method.


Technical Parameter

Specific surface area: ~909 m2/g

Pore size:~8.1 nm

 

Product Features

 

Low density: composed of C, H, O, N, B and other lightweight elements, low density.

High specific surface area: provides a large number of active sites and adsorption sites.

Chemical modifiability: Functional modifications can be made through the design and selection of organic monomers.

Good thermal stability and chemical stability: can maintain structural stability in a certain temperature and chemical environment.

Excellent pore properties: conducive to gas adsorption, storage and separation.

 

Application Fields

 

Gas storage and separation: COFs is known as a new type of porous crystal material for gas storage due to its high inherent specific surface area, extremely low density, high stability and adjustable pore size, such as storing hydrogen, carbon dioxide and other gases, and achieving efficient gas separation.

Catalysis: As a catalyst or catalyst carrier, participating in various chemical reactions. For example, improving the efficiency and selectivity of the reaction in organic synthesis. Its insolubility and high stability make it easy to separate from the reaction mixture, and the catalyst has good reusability.

Energy storage: Used for lithium-ion batteries, supercapacitors and other energy storage devices. Improve battery charging and discharging performance and cycle stability.

Sensing: Detect various substances in the environment, such as gas molecules, heavy metal ions, etc. It can be used for pollutant detection in environmental monitoring.

Liquid phase adsorption separation: A large number of open channels, large specific surface area, easy access to binding sites and high chemical stability make COF an excellent material for liquid phase adsorption.

Great book, but no new info for a huge Homer fan...
Format: Hardcover
Neat book, but anyone who is a huge Homer fan, like my husband (who the book was for) will not learn anything new - so I am told. Although there is a ton of great info in there about Homer and his friends/everyday life, it's a huge disappointment to hear that he already knows everything in the book. I guess that's a super-fan for you!

To funny
Format: Hardcover
If you’ve seen the show, then the book is just as funny. It takes all of Homer’s “advice” and puts it into a cute book. I have it on my shelf next to my Duff energy drink

Funny and unexpected
Format: Hardcover
I bought this book for my girlfriend who is a big Ralph Wiggum fan. When it arrived, I was shocked to see what a thorough exploration of the character it was. I'm not saying it's all canon in terms of the show, as i saw some complaints that there was stuff in this book that wouldn't make sense to the Ralph character (such as his love for Lisa) due to them "breaking up" in a past episode, but come on, that's a hogwash complaint. The whole point of this book is to entertain, and it does so in spades, so it comes highly recommended. And this is coming from a huge 'The Simpsons' fan himself. Oh, and by the way, my girlfriend loved it, too.
