Name:SFX-2,7-DDPA

Product Overview

Spiroaromatic hydrocarbons are an important organic semiconductor construction unit. Their unique non-planar spiroconjugation, cross conformation and steric hindrance effects can effectively improve the photoelectric properties and device stability of organic semiconductor materials. Spirofluorene xanthrene (SFX) one-pan preparation method due to its advantages of three bonds, high efficiency and fast, overcome the problems of lengthy synthesis route and expensive raw materials, and become a new generation of steric resistance construction unit, which has been widely used in frontier fields such as organic luminescence, organic laser, field effect transistor, perovskite solar cells, etc. It has become a model of green organic semiconductors. Due to the connection of spirofluorene and oxanthracene, the conjugated system of the entire molecule is extended, and the electrons can delocalize in a larger range, which has an important impact on its optical and electrical properties. Spirofluorenoxanthracene molecule has certain steric hindrance. The helical structure of spirofluorene and the large volume of oxanthracene make the molecules exhibit a specific arrangement in space. This steric hindrance affects the interactions between molecules and the way materials are stacked. For example, in crystal structures, molecules may adopt specific orientations that affect properties such as optical anisotropy of the material.

Product Features

Optical properties: It has unique luminous characteristics. Due to its extended conjugated system, its absorption and emission spectra differ from those of spirofluorene or oxanthrene alone. Generally, it has a strong absorption in the ultraviolet to visible region, and the emission spectrum covers a certain range of visible wavelengths. For example, its emission wavelength may range from blue to yellow-green, depending on factors such as the structure of the molecule and substituents.

The fluorescence quantum yield is relatively high. Compared with some common organic luminescent materials, the fluorescence quantum yield of spirofluorexanthrene can reach a higher level, which makes it have a potential application in the field of luminescence. For example, in some cases, its fluorescence quantum yield can exceed 30%, which can effectively convert absorbed energy into light energy emitted.

Electrical properties: As an organic semiconductor material, spirofluorenoxanthrene has a certain carrier transport capacity. Conjugated systems in its molecular structure contribute to the transport of electrons and holes. Electrical properties such as carrier mobility can be adjusted through appropriate molecular design and material treatment. For example, by introducing suitable substituents to improve the packing mode of molecules and charge transport channels, the carrier mobility is increased. The energy band structure can also be regulated. The band gap can be adjusted by chemical modification, such as changing the type and position of substituents. This is very important for its application in different optoelectronic devices, enabling it to adapt to different operating conditions and performance requirements.

Application Fields

Organic light-emitting diode (OLED) : Because of its good luminous performance, spirofluorexanthrene can be used as the luminous material of OLED. It can be used in the light-emitting layer of OLeds by doping or as the main material.

Organic field effect transistor (OFET) : As an organic semiconductor material, spirofluorexanthrene can be used to prepare the active layer of OFET. The properties of OFET, such as carrier mobility and switching ratio, can be improved by optimizing its molecular structure and film preparation process.

Bioimaging and sensing: The fluorescence properties of spirofluorexanthrene make it potentially useful in bioimaging and sensing. It can be used as a fluorescent probe to label biomolecules or cells, and observe physiological and pathological processes in organisms through fluorescence imaging technology.

All squeaker ball companies need to start doing this!!!!
Color: Orange - Pink, Size: 2.5"(Medium)-4 Pack
So first thing I want to say is that the manufacturer of these balls has thought of something that I am honestly shocked nobody has yet thought to do. They put the squeaker reed UNDER the fuzzy shell. GENIUS! I mean really, why aren't all squeaker ball companies doing this?!?! No wondering when it will finally pop out (or in) and it definitely prolongs the life of the squeaker significantly. My staffordshire/pit bull mix adores her squeakers, that said, they never last long especially when they are in a ball (her absolute fav toy on earth) The squeaker being protected alone warrants a 5 star review because it is simply genius. The fuzzy shell has yet to deteriorate and we have had these balls now almost 3 months so they have already outlasted other brands too. Now as for the sound itself, it is definitely different from a typical squeaker, not necessarily a bad thing. It is a "mild" squeak, not obnoxious a bit high pitched. Sounds more like a baby toy squeaker than a dog toy squeaker though....I'm not quite sure how I feel about the squeak. My dog has a preference for squeaker sounds. She prefers the little squeaker sound over the deeper louder sound from the bigger squeakers, these are closer to the sound she prefers but she doesn't LOVE it like I had hoped. The only other thing is that the ball itself feels as though it was blown up and plugged tight. Meaning (and believe me when I tell you my dog has a strong jaw) it is harder than most to make these balls squeak because you can't squeeze all the way down on the ball. It takes me two hands to make them squeak so my dog has a tough time squeaking them. She continually tries though so they are keeping her occupied. Overall I do recommend these balls because they are far safer than most eliminating the concern for your dog accidentally eating the squeaker and the longevity of their potential life. Try em, they are rugged enough for heavy chewers alike!

Tough enough to take rough play.
Color: Multicolor A, Size: 2.0"(Small)-6 Pack
They are smaller than I thought. That’s on me because I didn’t see the size. My dog loves them anyway and they are sturdy

Lucy The Dog Approved!
It's really not for me to say, with exception of the orange-blue color, which is ideal for still life. But the best part is how unglued the Lucy Dog gets at the sound of the squeaky toy knowing the hall leading to my apartment is instantly converted into a Dog Run. And she gets equally excited at the sight of any grassy area when on bike rides. So a feature that is truly the dog's bollocks is it's the perfect size for both Lucy's petite mouth and the all important emergency spare that fits securely under my bike saddle. In short, sublime perfection in Lucy The Dog's expert opinion.

Great fetch toy
Color: Multicolor B, Size: 2.5"(Medium)-6 Pack
My German Shepherd LOVES these. The size, squeak, & quality is the Perfect fetch ball. I use a blue ball throwing launcher and they work Great together. Will be buying more of these

If you have dogs that like to play fetch, these are a must have!
Color: Orange - Pink, Size: 2.0"(Small)-4 Pack
My pups love these sp much, they won't play with any balls other than these. Not sure if it's the small size, or the fact that they squeek, but they def were a hit.
