The article was titled 《Fundamental Characterization, Photophysics and Photocatalysis of a Base Metal Iron(II)-Cobalt(III) Dyad》, and you may find the article in Chemistry – A European Journal.Name: 4-Iodopyridine The information in the text is summarized as follows:

A new base metal iron-cobalt dyad has been obtained by connection between a heteroleptic tetra-NHC iron(II) photosensitizer combining a 2,6-bis[3-(2,6-diisopropylphenyl)imidazol-2-ylidene]pyridine with 2,6-bis(3-methyl-imidazol-2-ylidene)-4,4′-bipyridine ligand, and a cobaloxime catalyst. This novel iron(II)-cobalt(III) assembly has been extensively characterized by ground- and excited-state methods like X-ray crystallog., X-ray absorption spectroscopy, (spectro-)electrochem., and steady-state and time-resolved optical absorption spectroscopy, with a particular focus on the stability of the mol. assembly in solution and determination of the excited-state landscape. NMR and UV/Vis spectroscopy reveal dissociation of the dyad in acetonitrile at concentrations below 1 mM and high photostability. Transient absorption spectroscopy after excitation into the metal-to-ligand charge transfer absorption band suggests a relaxation cascade originating from hot singlet and triplet MLCT states, leading to the population of the 3MLCT state that exhibits the longest lifetime. Finally, decay into the ground state involves a 3MC state. Attachment of cobaloxime to the iron photosensitizer increases the 3MLCT lifetime at the iron center. Together with the directing effect of the linker, this potentially makes the dyad more active in photocatalytic proton reduction experiments than the analogous two-component system, consisting of the iron photosensitizer and Co(dmgH)2(py)Cl. This work thus sheds new light on the functionality of base metal dyads, which are important for more efficient and sustainable future proton reduction systems. In the part of experimental materials, we found many familiar compounds, such as 4-Iodopyridine(cas: 15854-87-2Name: 4-Iodopyridine)

Synthetic Route of C5H4INIn 2020 ,《A new class of ratiometric small molecule intracellular pH sensors for Raman microscopy》 appeared in Analyst (Cambridge, United Kingdom). The author of the article were Wilson, Liam T.; Tipping, William J.; Jamieson, Lauren E.; Wetherill, Corinna; Henley, Zoe; Faulds, Karen; Graham, Duncan; Mackay, Simon P.; Tomkinson, Nicholas C. O.. The article conveys some information:

Intracellular pH (pHi) homeostasis is intertwined with a myriad of normal cellular behaviors as well as pathol. processes. As such, small mol. probes for the measurement of pHi are invaluable tools for chem. biol., facilitating the study of the role of pH in cellular function and disease. The field of small mol. pHi sensors has traditionally been dominated with probes based on fluorescent scaffolds. In this study, a series of low mol. weight (<260) oligoyne compounds have been developed which exhibit pH sensitive alkyne stretching frequencies (νalkyne) in Raman spectroscopy. The modular design of the compounds enabled tuneability of their pKa(H) through simple structural modification, such that continuous pH sensitivity is achieved over the range 2-10. Alkyne stretching bands reside in the ′cell-silent′ region of the Raman spectrum (1800-2600 cm-1) and are readily detectable in a cellular environment with subcellular spatial resolution This enabled the application of a pH sensitive oligoyne compound to the ratiometric sensing of pHi in prostate cancer (PC3) cells in response to drug treatment. We propose that probes based on Alkyne Tag Raman Imaging offer an entirely new platform for the sensing of pHi, complementary to fluorescence microscopy.

A review. Up to now, much effort has focused on developing the highly efficiency composite photocatalysts by introducing cocatalysts in the photocatalytic hydrogen production reaction, because the proper cocatalysts can reduce activation energy, provide active sites, and suppress the reverse reaction. The transition metal nickel and its compounds acting as cocatalyst have received intensive attention because of their structural stability, facile preparation, and high performance in hydrogen evolution reaction, and are expected to replace the function of noble metals. This review emphasizes on the latest progresses that design and construction of composite photocatalyst using Ni-based cocatalyst for enhanced hydrogen production, such as metal nickel, nickel sulfide, and nickel phosphide, will be presented. Then, some preparation strategies and influence factors of Ni-based cocatalysts on enhanced photocatalytic hydrogen production are elucidated in detail. Finally, some challenge and perspective on the highly active cocatalysts in the area of photocatalytic hydrogen production from water splitting are also given.

Application of 624-73-7In 2017 ,《Investigation of the structural requirements of K-Ras(G12D) selective inhibitory peptide KRpep-2d using alanine scans and cysteine bridging》 was published in Bioorganic & Medicinal Chemistry Letters. The article was written by Niida, Ayumu; Sasaki, Shigekazu; Yonemori, Kazuko; Sameshima, Tomoya; Yaguchi, Masahiro; Asami, Taiji; Sakamoto, Kotaro; Kamaura, Masahiro. The article contains the following contents:

A structure-activity relationship study of a K-Ras(G12D) selective inhibitory cyclic peptide, KRpep-2d was performed. Alanine scanning of KRpep-2d focusing on the cyclic moiety showed that Leu7, Ile9, and Asp12 are the key elements for K-Ras(G12D) selective inhibition of KRpep-2d. The cysteine bridging was also examined to identify the stable analog of KRpep-2d under reductive conditions. As a result, the KRpep-2d analog (12) including mono-methylene bridging showed potent K-Ras(G12D) selective inhibition in both the presence and the absence of dithiothreitol. This means that mono-methylene bridging is an effective strategy to obtain a reduction-resistance analog of parent disulfide cyclic peptides. Peptide 12 inhibited proliferation of K-Ras(G12D)-driven cancer cells significantly. These results gave valuable information for further optimization of KRpep-2d to provide novel anti-cancer drug candidates targeting the K-Ras(G12D) mutant. 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.

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. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.
