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: ~1440 m2/g

Pore size:~3.63 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.

Very nice valet tray that gives a dresser or nightstand a much nicer look, and keeps EDC organized.
We’ve been using this sandalwood valet tray (with black "leather" inserts) for about five days, and it has quickly become a favorite for keeping the dresser top organized. It sits neatly on our tallboy dresser, staying put without any sliding, which is a big plus. The tray’s size is just right. This tray is not too bulky, but spacious enough to hold keys, watch, phone, etc., basically all the stuff carried in pockets daily. The wood has a smooth, polished feel, and the stain has a beautiful color which gives it a rich, elegant look that elevates the whole setup. What stands out most are the soft, leather-like inserts lining the compartments. They add a touch of luxury and keep items like my watch from getting scratched or sliding around with a slight bump. I also appreciate the thoughtful design of the notches cut out for phone charging cables. Having those notches makes it easy to keep a phone powered up without a mess of cords. This valet tray feels well-crafted and sturdy, though I would not mind it if the compartments were a tad deeper for bulkier items like a wallet. It’s practical and looks far more refined than the plastic trays I’ve used before, and I feel it gives an excellent value for the money, given today's pricing (July 20, 2025). For anyone looking to tidy up their space with something that feels upscale yet functional, this tray is worth a look.

5 ⭐️⭐️⭐️⭐️⭐️ STARS! Great valet tray for keys and wallets
This valet tray is very classy and made a beautiful wood with nice little touches all around in terms of design. I really like this on my side table in our foyer, and we place our keys, wallets and odd knickknacks that we bring in from time to time. This makes it very easy so not forget or replace things if we have a designated area like this valet pad. This gets my "TRIED-and-TRUE" SOLID 5 ⭐️⭐️⭐️⭐️⭐️ STARS Rating! I only give five star ratings to items that I use and exceed my expectations for quality, functionality, ease-of-use, premium appearance/looks, durability, & when possible: Sustainability/Ease on the Environment. I hope my review helped you gain some insight and I appreciate you taking the time to read it. Thank you!

very happy with my purchase
Color: Brown-F, Color: Brown-F
The quality and craftsmanship of this tray are amazing! I bought it mainly for jewelry photography, and the results turned out even better than I expected ✨ The matte finish is exactly what I needed because it doesn’t reflect light, which makes photographing jewelry and pearls so much easier and gives the photos a much more elevated look 📸 I took these photos at night under white lighting, and I’m honestly so happy with how they turned out. The background looks clean, soft, and aesthetic. Sharing some of my photos here for reference — highly recommend!

Amazing well thought out tray
Color: Brown, Color: Brown
Super well thought out tray. Looking amazing of course and the sizes of the slots are great. I can fit my large phone in the slot and it has a space for the charger on both ends. Love this tray.
