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: ~900m2/g

Pore size:~1.7nm

Product Features

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.

49" monitor great buy
Size: 49 inch
Great monitor. I use it for sim racing and all in have to say is wow. Ive had it for 3 weeks now and extremely happy with this monitor. The 165hrz is beautiful. I would definitely recommend this monitor. Also I got a 3 yr warranty with it. You can't go wrong and price is very good.

Very good monitor, definitely worth the price.
Size: 30Inch
Very good monitor, definitely worth the price. The picture quality and colors are great, and the mount is solid. The only issue is that it should come with a set of universal USB cables. I’m currently using it for a specific project, which required me to buy a particular cable. However, sometimes I would like to connect my laptop to it, but I’m still not sure which type of USB port or cable I need. Additionally, I had to purchase another USB cable to use it with my specific PC.

Very pleased, all 'round
Size: 32Inch
The screw heads are kind of soft, and fail. -0.2 stars, but rounds up to a five. PERFECT monitor for 3d modeling software. Plenty of real estate for the central work area and the associated controls on the side. Nice, clear, bright display (I'm toning down the brightness, next). I don't know the refresh rate and don't feel like looking at the specs, so I can't comment on gaming applications. A comment on the stand, it's not adjustable. I'll see if I can find a wall mount for the four screw-mounts, 80mm apart. My existing mount was 100mm -- more standard. Bizarre statements in the instructions, as is par for the course, but irrelevant. I am 0% unhappy with my purchase. Makes me really look forward to these li'l guys putting out that Type 004 carrier.

Good for the price
Size: 49 inch, Size: 49 inch
Update: The customer service was extremely helpful, which makes me believe this issue might have just been a one-off. They made it right. The price of this item is superb, but the quality is questionable. The resolution is good, the integrated lights behind it seem cool, and it was very easy to attach to the holder I already had. The issue I’m running into is that there’s something on the left side of the screen—right where I had my cursor in the picture I attached—that makes a popping sound every once in a while. It sounds very similar to what some old electronic devices do after they are turned off, likely due to expansion or contraction from temperature changes, but without enough space to do so quietly. It’s pretty distracting, so unfortunately I will have to return it. This might just be a manufacturing defect with this specific unit, but it’s still worth noting.

Amazing monitor for a great price
Size: 24inch, Size: 24inch
I enjoy gaming and spend a bit on the computer for my job so I wanted a good quality monitor for a good price. When I found this monitor I had to buy it twice! The color accuracy is decent but for this price, the screen size, response time, and durability has been amazing. I’ve had issues with the screen turning off a few times but I just switch the cords. Again for the price I got them at, I do not regret my decision.
