Product Overview

Carbon quantum dotsCQDs are quasi spherical amorphous carbon nanocrystals composed of sp2 and sp3 cluster carbon structures, surrounded by abundant oxygen-containing functional groups such as hydroxyl, carbonyl, carboxyl, etc. Their main constituent elements are C, H, O, and N. The luminescence mechanism of CQDs can be mainly attributed to these three types: quantum confinement effect, surface state luminescence, and molecular state luminescence. Carbon quantum dots are composed of C=C and C-C bond cores that are prone to π→π * transitions, as well as various organic molecular functional groups distributed on the surface that are prone to n →π * transitions. The structure and composition of carbon quantum dots result in strong absorption of short wavelength light waves in the ultraviolet range (260-320 nm), accompanied by low-intensity absorption of visible light (400-710 nm).

The preparation methods of carbon quantum dots are divided into top-down method and top-down method. The top-down method is to cut large-sized carbon structural materials through physical or chemical methods, mainly including arc discharge, laser ablation, ultrasonic treatment, and chemical oxidation. The bottom-up approach is to aggregate small molecule precursors into large-sized CQDs through chemical reactions, mainly including water/solvothermal, template method, microwave-assisted, and solid-phase methods.

Hydrophobic carbon quantum dots are a special type of carbon quantum dot. Compared with common hydrophilic carbon quantum dots, their surface chemical groups or modifications make them less soluble in aqueous phase, while they have better solubility in non-polar or weakly polar organic solvents. More suitable for dispersion and application in non-polar solvents such as DMF, toluene, n-hexane, chloroform, etc.

Product Features

 

Surface characteristics: The functional groups on the surface are mainly hydrophobic, such as long-chain alkyl groups, aromatic rings, etc., which make them difficult to disperse in aqueous phase, but have good solubility in non-polar organic solvents.

Optical properties: It has unique light absorption and emission characteristics, and its fluorescence emission wavelength may vary due to different preparation methods and surface modifications. Compared to hydrophilic carbon quantum dots, their optical properties may be relatively insensitive to changes in environmental polarity.

Stability: Due to the presence of hydrophobic groups on the surface, it may have better chemical and thermal stability in some organic solvents.


Application Fields

 

 

Organic light-emitting diode (OLED): As a material for the light-emitting layer, its hydrophobicity helps to better integrate with other organic layers, improving the device's luminous efficiency and lifespan. For example, in multi-layer structured OLEDs, hydrophobic carbon quantum dots can improve charge and energy transfer processes, thereby enhancing luminescence performance.

Organic photovoltaic devices: used to improve the light absorption and charge separation efficiency of photovoltaic materials. For example, incorporating it into organic semiconductors to improve their photoelectric conversion performance.

Organic catalysis: can participate in organic reactions as a catalyst or co catalyst. For example, in some hydrogenation reactions, hydrophobic carbon quantum dots can promote the progress of the reaction and improve selectivity.

Biomedical applications: Although hydrophobicity limits its direct in vivo application, it can be used to construct nanocarriers with specific functions. For example, by combining with hydrophobic drugs, drug encapsulation and controlled release can be achieved.

Sensor: used to detect specific substances in organic solvents. For example, detecting the concentration of organic pollutants or chemicals in non-aqueous systems.

For aggressive chewers.
The product lasted all of 20-40 min. I wasn't timing him chewing. But he was quick to get off the head. He had fun but he must be in a different category than aggressive chewer.

Great buy, finally a big soft toy, and so cute
Color: Green
This octopus toy is so adorable, I’m truly so impressed with the size finally a big toy for a big dog. She loves it! It squeaks, soft, made great. Worth it! Love it! Fun, durable n chewability just for play materials soft n durable. It’s a sea foam green color and creme beautiful neutral color

Large, excellent toy with many squeakers!
Color: Blue, Color: Blue
This toy is excellent! I’m super happy with this purchase. My dog loves squeakers and there are so many in this toy, plus stuffing for her to rip out, and crinkle paper to take the sensory experience up another notch! It’s also more durable than many other plush-type dog toys, and is larger than expected which is a plus in my book. For size reference, both dogs are around 40lbs. I will be buying another as soon as this one is demolished!

Huge and fun. Good for two dogs to play with together.
Color: Yellow
This dog toy is great! And it's HUGE. Each tentacle crinkles, and the dogs love to play tug-of-war with it. It seems to be holding up well, too. It seemed a bit pricy for a dog toy, but it turns out it was worth it.

My dogs new favorite toy!
Color: Blue
His new favorite toy! My dog absolutely loves it!!! It’s much bigger than I thought it would be so my dog has to be careful when he’s running with it because he will trip on the legs of the octopus. The best part is there is a little squeaker in the bottom of each leg! Bonus!!! If your dog chews up stuffed animals, this will be no different. It is a stuffed animal. My baby just likes to carry it around and squeak it a 1000 times a day. Don’t mind my crazy voice in the video. That’s the voice I use when he’s excited about a toy. He greets me every day with his octopus.🥰
