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.

It’s so invisible
So basically, I am 15 I accidentally went to my school in these but during free period my friend told me I was so embarrassed because at that point all the moisture became out of it and it was very visible. It’s not a bad product just to make sure to take it off before school/work.

Skin care for Mature Skin
I have Mature skin. I have tried many products to no avail. These 3 Korean products did my skin wonders on day 1. My very favorite is the Oil Cleaner. 2 are the toner pads that have Collagen Peptides and Rice Water. They're thin and you really can place them on your face like a sheet mask. Amazing! 3 the Pore Minimizer Serum shrank the large pores on each side of my nose. It leaves my skin So Pretty that I don't wear makeup but on special occasions. The price is a steal also.

Unbelievable results even for a skeptic like me!
I honestly don't know what witchcraft this brand uses, but I was given their eye patches as a gift and could not believe how well they worked. I am hugely skeptical, usually only believe really in actual Botox, plastic surgery, etc. So I thought the eye patches would be a waste of time. But I put them one one morning when my under eye area was all wrinkled and dried up like a prune. They were MAGIC. Then recently I saw these masks and thought I'd better try them. I have EXTREMELY SENSITIVE skin, to the point where I need regular dermatological care and can't use ANYTHING on my face. My cheeks burn and are red and like sandpaper ALL the time. But I put this mask on around 7 AM when my skin was at its most calm and non-red. I left it on for about 50 mins. Unbelievable results. My whole face is moisturized, nothing hurts, everything looks tight but feels lovely. Really impressed. I'll try to take pics next time and edit this.

Best mask ever used.
I am amazed by this mask! I used last night for the first time and am seeing smoother skin this morning! I've used a few other masks, to include a very expensive one that promises immediate results, but none of them compare to what I am seeing this morning! I subscribed to receive these on an ongoing basis and am so glad I did.

Worked great for my skin
First time I used this face mask was after a 10 minute Vitamin C 'peel' and application of 1.5%glycolic acid (with a facial pad). Left it on for about 45 minutes at which point the mask felt 'dry'. My skin felt so soft afterwards- it literally absorbed all of the moisturizing elements. Easy to apply and stayed put until removed. Highly recommend!
