Azides and acetylenes are bio-orthogonal functional groups that can be readily coupled using copper(I)- or ruthenium(II)- catalyzed 1,3-dipolar cycloaddition reactions. Using non-fluorescent aromatic azides and aromatic acetylenes, covering a range of electron rich and poor building blocks, the Huisgen cycloaddition afford 1,4-disubstituted or 1,5-disubstituted 1,2,3-triazoles. Using a combinatorial approach by running reaction in parallel in polypropylene 96-well plates we discovered several new fluorescent 1,2,3-triazoles scaffolds.

Catalytic promiscuity enabled by photoredox catalysis in nicotinamide-dependent oxidoreductases was written by Biegasiewicz, Kyle F.;Cooper, Simon J.;Emmanuel, Megan A.;Miller, David C.;Hyster, Todd K.. And the article was included in Nature Chemistry in 2018.SDS of cas: 1072-53-3 This article mentions the following:

Strategies that provide enzymes with the ability to catalyze non-natural reactions are of considerable synthetic value. Photoredox catalysis has proved adept at expanding the synthetic repertoire of existing catalytic platforms, yet, in the realm of biocatalysis it has primarily been used for cofactor regeneration. Here we show that photoredox catalysts can be used to enable new catalytic function in nicotinamide-dependent enzymes. Under visible-light irradiation, xanthene-based photocatalysts enable a double-bond reductase (DBR) to catalyze an enantioselective deacetoxylation. Mechanistic experiments support the intermediacy of an α-acyl radical, formed after the elimination of acetate. Isotopic labeling experiments support nicotinamide as the source of the hydrogen atom. Preliminary calculations and mechanistic experiments suggest that binding to the protein attenuates the reduction potential of the starting material, an important feature for localizing radical formation to the enzyme active site. The generality of this approach is highlighted with the radical dehalogenation of α-bromoamides catalyzed by ketoreductases (KREDs) with Eosin Y as a photocatalyst. In the experiment, the researchers used many compounds, for example, 1,3,2-Dioxathiolane 2,2-dioxide (cas: 1072-53-3SDS of cas: 1072-53-3).

1,3,2-Dioxathiolane 2,2-dioxide (cas: 1072-53-3) belongs to benzothiophene derivatives. Benzothiophene is used as starting material for the synthesis of bioactive molecules.

Designer Cathode Additive for Stable Interphases on High-Energy Anodes was written by Tian, Mengyu;Ben, Liubin;Yu, Hailong;Song, Ziyu;Yan, Yong;Zhao, Wenwu;Armand, Michel;Zhang, Heng;Zhou, Zhi-Bin;Huang, Xuejie. And the article was included in Journal of the American Chemical Society in 2022.Recommanded Product: 1,3,2-Dioxathiolane 2,2-dioxide This article mentions the following:

Rechargeable lithium-based batteries built with high-energy anode materials (e.g., silicon-based and silicon-derivative materials) are considered a feasible solution to satisfy the stringent requirements imposed by emerging markets, including elec. vehicles and grid storage, due to their higher energy d. compared to contemporary lithium-ion batteries. The robustness of the solid electrolyte interphase (SEI) layer on high-energy anodes is critical to achieve long-term and stable cycling performances of the batteries. Herein, we propose a new type of designer cathode additive (DCA), i.e., an ultrathin coating layer of elemental sulfur on the cathode, for the in situ formation of a thin and robust SEI layer on various types of high-energy anodes. The DCA elemental sulfur undergoes simultaneous oxidation and reduction paths, forming lithium alkyl sulfate (R-OSO₂OLi) and poly(ethylene oxide) (PEO)-like polymers on the anode surface. The as-formed R-OSO₂OLi/PEO-modified SEI layer has good lithium cation (Li⁺) permeability to facilitate fast ion transportation across the interphases and superior elasticity to adapt to large volume changes, which is particularly effective for improving the cycling efficiency of high-energy anodes (e.g., ca. 14-35% increase in capacity retention for the silicon-carbon composite (SiC) or silicon-tin alloy (Si-Sn)||LiFePO₄ cells). The present work opens a new avenue toward the practical deployment of high-energy rechargeable lithium-based batteries. In the experiment, the researchers used many compounds, for example, 1,3,2-Dioxathiolane 2,2-dioxide (cas: 1072-53-3Recommanded Product: 1,3,2-Dioxathiolane 2,2-dioxide).

Rational design of reversibly photochromic molecules with aggregation-induced emission by introducing photoactive thienyl and benzothienyl groups was written by Zhou, Shasha;Guo, Sidan;Liu, Weidong;Yang, Qiaoying;Sun, Huili;Ding, Riqing;Qian, Zhaosheng;Feng, Hui. And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2020.Related Products of 113893-08-6 This article mentions the following:

Herein, we proposed a general strategy to design reversible photochromic mols. with solid-state fluorescence by introducing photoactive thienyl and benzothienyl groups into an AIE-active mol. skeleton. The combination of a thienyl or benzothienyl group and a triphenylethene in the right manner enabled the mols. to possess unique aggregation-induced emission properties and reversible photo-controlled changes in color and fluorescence in solid state. Theor. anal. revealed that photo-triggered cyclization and cycloreversion reactions were responsible for the reversible photochromism and photoinduced fluorescence switching, and the enlargement of the conjugation of the introduced photoactive units can significantly promote the cyclization reactions and the photochromic processes. The excellent performance of these photochromic mols. with aggregation-induced emission activity in a photoswitchable patterning paper and multiple encryption of anti-counterfeiting of a banknote demonstrated that they are perfectly suited for surface-involved photo-controlled applications such as information storage and data encryption.
