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.

Must have toy
Found out the hard way my sweet little shy rescue pup can chew through any toy in under 5 min. If it says indescribable they have never met her....until this toy. It has been almost two weeks now. She loves this thing and you cannot tell she has even tried to destroy it. If she does manage to somehow I am instantly buying another. This thing is awesome, a must have for super cheers, and she LOVES it

Not even close to "virtually indestructible" as described.
Within an hour of receiving this K9 Chew Stick, our 55lb Staffordshire Terrier began chewing pieces off the top of toy. Initially, we were happy to see that our dog enjoyed the chew toy, and it appeared to be durable. For the high cost of this toy, it is very disappointing that pieces can start coming off that quickly. Luckily, our dog wasn't swallowing the pieces, which can easily lodge in their intestines. If your dog is NOT an aggressive/determined chewer or they are happy with chewing for very short periods of time, this toy might be okay for them.

Durable for Heavy Chewing Rottweiler
Fit for Rottweiler, indestructible and ordered the Y stick from them as well! Lasted longer than any other toy I’ve given her. Kong who?

Dogs love them
Color: Skull Print, Size: 6 inches
I ordered 3 of these well made balls with pull strips for my 2 Aussys. easy to inflate. Dogs have great fun. Sure beats a simple ball.

Any toy that last over 2 days with a Belgian deserves 5 stars. I purchased this for my pup's 2nd birthday. She loves it. Within in 24hrs all the tabs were chewed off but the ball itself is still holding up. She plays volleyball with it, catch, Chase, and chews on it. It is going on a month and it is still around. Thank you. It is difficult to find a toy that lasts with a Belgian and they are hyper dogs that need toys.
