The article was titled 《A donor-acceptor complex enables the synthesis of E-olefins from alcohols, amines and carboxylic acids》.Computed Properties of C10H18INO2 The article contains the following contents:

Herein, a fundamentally distinct strategy enabled by electron donor-acceptor (EDA) complexes was presented for the selective synthesis of olefins from simple and easily available starting materials such as alcs., amines and carboxylic acids. The conversions took place via photoactivation of the EDA complexes of the activated substrates with alkali salts, followed by hydrogen atom elimination from in-situ generated alkyl radicals. This method was operationally simple and straightforward and free of photocatalysts and transition-metals, and showed high regio- and stereoselectivities. In the part of experimental materials, we found many familiar compounds, such as tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3Computed Properties of C10H18INO2)

Product Details of 589-87-7 And the article was included in ACS Energy Letters in 2020. The article conveys some information:

The hole-transporting layer is an essential component in a perovskite solar cell (PSC) and plays a key role in controlling both power conversion efficiency (PCE) and stability. Here, a new hole-transporting material (HTM), methoxy group-containing poly(triarylamine) (PTAA) (CH3O-PTAA) is reported for efficient PSCs with improved thermal stability. As compared to commonly used PTAA (CH3-PTAA), CH3O-PTAA exhibits enhanced doping ability and stability under thermal stress. With CH3O-PTAA, (FAPbI3)0.85(MAPbBr3)0.15-based PSCs show high PCEs > 20%, comparable to those of CH3-PTAA devices. More importantly, better long-term thermal stability with only 3% reduction from the initial PCE (6.1% reduction on average) has been achieved for encapsulated PSCs with CH3O-PTAA than that of PSCs with CH3-PTAA under dark storage conditions (ISOS-D-3) of 85° and 85% relative humidity (RH) over 1000 h. Detailed studies have been conducted to reveal the strong correlation between the doping behavior of HTMs and the performance of PSCs, which provide useful guidelines for the design of new HTMs for efficient and stable PSCs.

《Enhancing near-infrared photoluminescence from single-walled carbon nanotubes by defect-engineering using benzoyl peroxide》 was published in Scientific Reports in 2020. These research results belong to Przypis, Lukasz; Krzywiecki, Maciej; Niidome, Yoshiaki; Aoki, Haruka; Shiraki, Tomohiro; Janas, Dawid. Category: iodides-buliding-blocks The article mentions the following:

Single-walled carbon nanotubes (SWCNTs) have been modified with ester groups using typical organic radical chem. Consequently, traps for mobile excitons have been created, which enhanced the optical properties of the material. The proposed methodol. combines the benefits of mainstream approaches to create luminescent defects in SWCNTs while it simultaneously avoids their limitations. A step change was achieved when the aqueous medium was abandoned. The selection of an appropriate organic solvent enabled much more facile modification of SWCNTs. The presented technique is quick and versatile as it can engage numerous reactants to tune the light emission capabilities of SWCNTs. Importantly, it can also utilize SWCNTs sorted by chirality using conjugated polymers to enhance their light emission capabilities. Such differentiation is conducted in organic solvents, so monochiral SWCNT can be directly functionalized using the demonstrated concept in the same medium without the need to redisperse the material in water. In the part of experimental materials, we found many familiar compounds, such as 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Category: iodides-buliding-blocks)

The author of 《Catalytic asymmetric acetalization of carboxylic acids for access to chiral phthalidyl ester prodrugs》 were Liu, Yingguo; Chen, Qiao; Mou, Chengli; Pan, Lutai; Duan, Xiaoyong; Chen, Xingkuan; Chen, Hongzhong; Zhao, Yanli; Lu, Yunpeng; Jin, Zhichao; Chi, Yonggui Robin. And the article was published in Nature Communications in 2019. Product Details of 619-58-9 The author mentioned the following in the article:

Carboxylic acids are common moieties in medicines. They can be converted to phthalidyl esters as prodrugs. Unfortunately, phthalidyl esters are now mostly prepared in racemic forms. This is not desirable because the two enantiomers of phthalidyl esters likely have different pharmacol. effects. Here, the authors address the synthetic challenges in enantioselective modification of carboxylic acids via asym. acetalizations. The key reaction step involves asym. addition of a carboxylic acid to the catalyst-bound intermediate. This addition step enantioselectively constructs a chiral acetal unit that leads to optically enriched phthalidyl esters. A broad range of carboxylic acids react effectively under mild and transition metal-free conditions. Preliminary bioactivity studies show that the two enantiomers of chlorambucil phthalidyl esters exhibit different anti-cancer activities to inhibit the growth of Hela cells. Our catalytic strategy of asym. acetalizations of carboxylic acids shall benefit future development of chiral phthalidyl ester prodrugs and related mols. In addition to this study using 4-Iodobenzoic acid, there are many other studies that have used 4-Iodobenzoic acid(cas: 619-58-9Product Details of 619-58-9) was used in this study.

4-Iodobenzoic acid(cas: 619-58-9) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Product Details of 619-58-9 Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.

Quality Control of 1,2-DiiodoethaneIn 2022 ,《Structural Reconstruction in Lead-Free Two-Dimensional Tin Iodide Perovskites Leading to High Quantum Yield Emission》 appeared in ACS Energy Letters. The author of the article were Ghimire, Sushant; Oldenburg, Kevin; Bartling, Stephan; Lesyuk, Rostyslav; Klinke, Christian. The article conveys some information:

The authors report a structural reconstruction-induced high photoluminescence quantum yield of 25% in colloidal 2-dimensional Sn iodide nanosheets that are synthesized by a hot-injection method. The as-synthesized red-colored nanosheets of octylammonium Sn iodide perovskites at room temperature transform to white hexagonal nanosheets upon washing or exposure to light. This structural change increases the bandgap from 2.0 to 3.0 eV, inducing a large Stokes shift and a broadband emission. Further, a long photoluminescence lifetime of ∼1 μs is measured for the nanosheets. Such long-lived broad and intense photoluminescence with a large Stokes shift is anticipated to originate from Sn iodide clusters that are formed during the structural reconstruction. The stereoactive 5s2 lone pair of Sn(II) ions perturbs the excited state geometry of the white hexagonal nanosheets and facilitates the formation of self-trapped excitons. Such broadband and intensely emitting metal halide nanosheets are promising for white light-emitting diodes. The experimental part of the paper was very detailed, including the reaction process of 1,2-Diiodoethane(cas: 624-73-7Quality Control of 1,2-Diiodoethane)

1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom.

Application of 516-12-1In 2021 ,《Chemical synthesis of the pentasaccharide repeating unit of the O-specific polysaccharide from Ruminococcus gnavus》 appeared in Carbohydrate Research. The author of the article were Pal, Debasish; Naskar, Mrinal; Bera, Anirban; Mukhopadhyay, Balaram. The article conveys some information:

The Gram-pos. bacterium Ruminococcus gnavus (R. gnavus) has been identified to be responsible for symptoms of Crohn’s disease. R. gnavas produces a glucorhamnan polysaccharide and it is postulated that this polysaccharide induces inflammatory response through toll-like receptor 4 (TLR4). The current manuscript describes the chem. synthesis of the pentasaccharide repeating unit of the O-polysaccharide from R. gnavus. The major challenge associated with this particular synthesis is the presence of two consecutive 1,2-cis glucose units. The target oligosaccharide is achieved through a linear strategy from com. available sugars through rational protecting group manipulation. 1,2-cis glycosylation of glucose through remote participation of acyl group at the 6-O position is used successfully with excellent yield. In both cases, sole 1,2-cis products are obtained at -20°C through the activation of thioglycosides. In the experiment, the researchers used many compounds, for example, 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Application of 516-12-1)
