In 2019,Acta Crystallographica, Section C: Structural Chemistry included an article by Lee, Sunhee; Kwak, Soyoung; Lee, Keumhee; Kim, Byung Gi; Kim, Minseong; Wang, Dong Hwan; Han, Won-Sik. COA of Formula: C7H7I. The article was titled 《Tuning the energy level of TAPC: crystal structure and photophysical and electrochemical properties of 4,4′-(cyclohexane-1,1-diyl)bis[N,N-bis(4-methoxyphenyl)aniline]》. The information in the text is summarized as follows:

The energy level of a hole-transporting material (HTM) in organic electronics, such as organic light-emitting diodes (OLEDs) and perovskite solar cells (PSCs), is important for device efficiency. In this regard, we prepared 4,4′-(cyclohexane-1,1-diyl)bis[N,N-bis(4-methoxyphenyl)aniline] (TAPC-OMe), C46H46N2O4, to tune the energy level of 4,4′-(cyclohexane-1,1-diyl)bis[N,N-bis(4-methylphenyl)aniline] (TAPC), which is a well-known HTM commonly used in OLED applications. A systematic characterization of TAPC-OMe, including 1H and 13C NMR, elemental anal., UV-Vis absorption, fluorescence emission, d. functional theory (DFT) calculations and single-crystal X-ray diffraction, was performed. TAPC-OMe crystallized in the triclinic space group P [inline formula omitted] , with two mols. in the asym. unit. The dihedral angles between the central amine triangular planes and those of the Ph groups varied from 26.56 (9) to 60.34 (8)° due to the steric hindrance of the central cyclohexyl ring. This arrangement might be induced by weak hydrogen bonds and C-H···π(Ph) interactions in the extended structure. The emission maxima of TAPC-OMe showed a significant bathochomic shift compared to that of TAPC. A strong dependency of the oxidation potentials on the nature of the electron-donating ability of substituents was confirmed by comparing oxidation potentials with known Hammett parameters (σ). The experimental process involved the reaction of 1-Iodo-4-methylbenzene(cas: 624-31-7COA of Formula: C7H7I)

In 2019,Chemical Communications (Cambridge, United Kingdom) included an article by Shiino, Keisuke; Miyake, Junpei; Miyatake, Kenji. Synthetic Route of C6H4ClI. The article was titled 《Highly stable polyphenylene ionomer membranes from dichlorobiphenyls》. The information in the text is summarized as follows:

A simple, cost-effective synthetic strategy for highly stable, proton conductive polyphenylene membranes is reported. The title polyphenylene ionomer (SPP-BP) is easily prepared from dichlorobenzenesulfonic acid and dichlorobiphenyls. The SPP-BP membrane with an optimized m-biphenylene/p-biphenylene ratio (i.e., 4 : 1) for a hydrophobic moiety exhibits outstanding chem. stability as well as high proton conductivity In the part of experimental materials, we found many familiar compounds, such as 1-Chloro-3-iodobenzene(cas: 625-99-0Synthetic Route of C6H4ClI)

1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides.Synthetic Route of C6H4ClI The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.

In 2022,Minemoto, S.; Mun, J. H.; Teramoto, T.; Yagishita, A.; Tsuru, S. published an article in Journal of Electron Spectroscopy and Related Phenomena. The title of the article was 《Ultrafast X-ray photoelectron diffraction from free molecules: Simulations of diffraction profiles from transient intermediates in the elimination reaction of C2H4I2》.Application of 624-73-7 The author mentioned the following in the article:

We have performed the simulations of C 1 s X-ray photoelectron diffraction (XPD) profiles from C2H4I2, bridged and classical anti-forms of C2H4I intermediates and C2H4 products to capture structures of transient intermediates in the elimination reaction of C2H4I2, under our ultrafast X-ray photoelectron diffraction (UXPD) scheme for free mols. using soft X-ray free-electron laser (SXFEL). In the UXPD scheme, the sample mols. are aligned in advance by near-IR (NIR) laser with ns pulse duration before applying a pump – probe method. Then, we have considered alignment control of C2H4I2 by using the elliptically polarized NIR laser to realize the UXPD experiments for the free mols. As the results of simulations of XPD profiles from the laser-aligned C2H4I2 mols., we have demonstrated the two-dimensional (2D) color maps of the C 1 s XPD profiles from C2H4I2, C2H4I, and C2H4. The 2D color maps have revealed that the transient C 1 s XPD profiles from the bridged-form and classical anti-form C2H4I intermediates exhibit remarkable differences, reflecting different intra-mol. scattering pathways of C 1 s photoelectrons within the intermediates. Thus, the present result has proved that UXPD for the free mols. has an advantage, compared with other traditional diffraction methods. In addition to this study using 1,2-Diiodoethane, there are many other studies that have used 1,2-Diiodoethane(cas: 624-73-7Application of 624-73-7) was used in this study.

In 2022,Bosch, Eric; Bowling, Nathan P. published an article in Acta Crystallographica, Section C: Structural Chemistry. The title of the article was 《Co-operative halogen bonds and nonconventional sp-C-H·O hydrogen bonds in 1:1 cocrystals formed between diethynylpyridines and N-halosuccinimides》.Product Details of 516-12-1 The author mentioned the following in the article:

The rapid evaporation of 1:1 solutions of diethynylpyridines and N-halosuccinimides, that react together to form haloalkynes, led to the isolation of unreacted 1:1 cocrystals of the two components. The 1:1 cocrystal formed between 2,6-diethynylpyridine and N-iodosuccinimide (C4H4INO2·C9H5N) contains an N-iodosuccinimide-pyridine I·N halogen bond and two terminal alkyne-succinimide carbonyl C-HO hydrogen bonds. The three-dimensional extended structure features interwoven double-stranded supramol. polymers that are interconnected through halogen bonds. The cocrystal formed between 3,5-diethynylpyridine and N-iodosuccinimide (C4H4INO2.C9H5N) also features an I·N halogen bond and two C-H·O hydrogen bonds. However, the components form essentially planar double-stranded one-dimensional zigzag supramol. polymers. The cocrystal formed between 3,5-diethynylpyridine and N-bromosuccinimide (C4H4BrNO2.C9H5N) is isomorphous to the cocrystal formed between 3,5-diethynylpyridine and N-iodosuccinimide, with a Br·N halogen bond instead of an I·N halogen bond. In the experiment, the researchers used many compounds, for example, 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Product Details of 516-12-1)

In 2022,Kittikhunnatham, Preecha; Leith, Gabrielle A.; Mathur, Abhijai; Naglic, Jennifer K.; Martin, Corey R.; Park, Kyoung Chul; McCullough, Katherine; Jayaweera, H. D. A. Chathumal; Corkill, Ryan E.; Lauterbach, Jochen; Karakalos, Stavros G.; Smith, Mark D.; Garashchuk, Sophya; Chen, Donna A.; Shustova, Natalia B. published an article in Angewandte Chemie, International Edition. The title of the article was 《A Metal-Organic Framework (MOF)-Based Multifunctional Cargo Vehicle for Reactive-Gas Delivery and Catalysis》.Category: iodides-buliding-blocks The author mentioned the following in the article:

The efficient delivery of reactive and toxic gaseous reagents to organic reactions was studied using metal-organic frameworks (MOFs). The simultaneous cargo vehicle and catalytic capabilities of several MOFs were probed for the first time using the examples of aromatization, aminocarbonylation and carbonylative Suzuki-Miyaura coupling reactions. These reactions highlight that MOFs served a dual role as a gas cargo vehicle and a catalyst, led to product formation with yields similar to reactions employing pure gases. Furthermore, the MOFs was recycled without sacrificing product yield, while simultaneously maintaining crystallinity. The reported findings were supported crystallog. and spectroscopically (e.g., diffuse reflectance IR Fourier transform spectroscopy), foreshadowing a pathway for the development of multifunctional MOF-based reagent-catalyst cargo vessels for reactive gas reagents as an attractive alternative to the use of toxic pure gases or gas generators. The results came from multiple reactions, including the reaction of 4-Chloro-2-iodoaniline(cas: 63069-48-7Category: iodides-buliding-blocks)

4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.Category: iodides-buliding-blocks
