Effective fluorescent sensing of Na⁺ ion by calix[4]arene bearing pyrene and perylene based on energy transfer was written by Nishimura, Yukihiro;Takemura, Tetsuo;Arai, Sadao. And the article was included in ARKIVOC (Gainesville, FL, United States) in 2007.Application of 80480-15-5 The following contents are mentioned in the article:

A new calix[4]arene having pyrene and perylene moieties has been synthesized as a Na⁺ detectable fluorescent ionophore. When excited at the pyrene moiety (342 nm) of the ionophore, a strong fluorescence emission of the perylene moiety (535 nm) was observed due to energy transfer from the pyrene to perylene. By addition of Na⁺ at a low concentration in the range of 2.5-10 μM, the fluorescence was remarkably quenched. In contrast to the fluorescent behavior by the ionophore having pyrene and perylene moieties, the excimer emission of a calix[4]arene derivative having two pyrene moieties decreased by the addition of Na⁺ with a concentration in the range of 50-200 μM. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Application of 80480-15-5).

2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Application of 80480-15-5

Solubilization of carbon nanotubes with a pyrene-carrying polymer in water was written by Nakashima, Naotoshi;Okuzono, Shingo;Tomonari, Yasuhiko;Murakami, Hiroto. And the article was included in Transactions of the Materials Research Society of Japan in 2004.Application of 80480-15-5 The following contents are mentioned in the article:

A pyrene-bearing vinyl monomer and a copolymer with acrylamide were synthesized. Transmission electron microscopy and at. force microscopy data revealed that both the monomer and copolymer dissolved/dispersed single-walled carbon nanotubes (SWNTs) in water under direct sonication with an ultrasonic cleaner. The dissolution/dispersion of SWNTs by the compounds in water is attributed to phys. adsorption of the pyrene group onto the side wall of the nanotubes. Upon heating up to 49-50°, an aqueous solution of SWNTs-monomer produced a precipitate, which was readily separated from the solution/dispersion by filtration as a solid nanocomposite. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Application of 80480-15-5).

In this article, we describe a facile and effective method for the modification of multiwall carbon nanotubes with mol. anchor mols. using supercritical fluids (SCFs). Through choice of deposition conditions, the degree of loading in these nanotube-anchor structures can be controlled to achieve sub-monolayer, monolayer, or greater-than-monolayer coverage. This level of control represents a potential advantage of SCFs over liquid solvents for anchor deposition. Employment of the described technique is expected to enable the direct addition of desired chem. functionality to many carbon nanotube structures for a variety of applications. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Electric Literature of C18H11BrO).

2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Electric Literature of C18H11BrO

And the article was included in Journal of Organometallic Chemistry in 2022.HPLC of Formula: 80480-15-5 The following contents are mentioned in the article:

The biol. relevant arenes Et salicylate and salicylic amide as well as the fluorescent coumarin and pyrene units were functionalized with a cyclopentadiene unit. The Re and ^99mTc complexes of the latter two were synthesized and fully characterized. During crystallization of the ligands, [2+2] and [6+6] cycloadditions were observed for the cyclopentadiene modified coumarin. A light-induced mechanism, supported by DFT calculations, is proposed for these reactions. The fluorescent properties of the coumarin and pyrene based cyclopentadienes and their corresponding Re complexes were investigated. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5HPLC of Formula: 80480-15-5).

2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.HPLC of Formula: 80480-15-5

Reversible aggregation between nanoparticles induced by acid-base interactions was written by Ionita, Gabriela;Ghica, Corneliu;Turcu, Ioana;Ionita, Petre. And the article was included in Chemical Physics Letters in 2012.Recommanded Product: 80480-15-5 The following contents are mentioned in the article:

Acid-base interactions between amino-silica and carboxyl-gold protected nanoparticles, functionalized or not with free stable radicals or fluorescent moieties, were studied by ESR, fluorescence, and TEM. While those nanoparticles are stable in solution, mixing them induces aggregation, due to acid-base interactions; addition of a base or an acid redissolves them. By ESR, strong spin-spin interactions were noticed; by fluorescence, only small differences may be observed, while by TEM, it was noticed that gold nanoparticles are distributed evenly on the surface of the silica nanoparticles. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Recommanded Product: 80480-15-5).

2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine.

An Indirect Synthetic Approach toward Conformationally Constrained 20-Membered Unclosed Cryptands via Late-Stage Installation of Intraannular Substituents was written by Jurczak, Janusz;Sobczuk, Adam;Dabrowa, Kajetan;Lindner, Marcin;Niedbala, Patryk. And the article was included in Journal of Organic Chemistry.Related Products of 80480-15-5 The following contents are mentioned in the article:

A new protocol for PTC-mediated O-alkylation of the intraannular position of 20-membered unclosed cryptands (UCs) is reported. In contrast to the classical, “direct” strategy, which requires functionalization of the lariat arm at the beginning of synthesis, this “indirect” approach enables the late-stage introduction of various benzylic substituents after an unfavorable macrocyclization step (11 examples, yields up to 98%). Notably, this method permits preparation of, previously inaccessible, crowded UCs bearing a 1-acetylpyrene substituent and a dimer joined by p-xylene linker. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Related Products of 80480-15-5).

Organobromine compounds have fallen under increased scrutiny for their environmental impact. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Related Products of 80480-15-5
