Y.; Zhang, Haoke; Tang, Ben Zhong published an article in Nature Communications. The title of the article was 《Secondary through-space interactions facilitated single-molecule white-light emission from clusteroluminogens》.Recommanded Product: 4-Iodobenzaldehyde The author mentioned the following in the article:

Clusteroluminogens refer to some non-conjugated mols. that show visible light and unique electronic properties with through-space interactions due to the formation of aggregates. Although mature and systematic theories of mol. photophysics have been developed to study conventional conjugated chromophores, it is still challenging to endow clusteroluminogens with designed photophys. properties by manipulating through-space interactions. Herein, three clusteroluminogens with non-conjugated donor-acceptor structures and different halide substituents are designed and synthesized. These compounds show multiple emissions and even single-mol. white-light emission in the crystalline state. The intensity ratio of these emissions is easily manipulated by changing the halide atom and excitation wavelength. Exptl. and theor. results successfully disclose the electronic nature of these multiple emissions: through-space conjugation for short-wavelength fluorescence, through-space charge transfer based on secondary through-space interactions for long-wavelength fluorescence, and room-temperature phosphorescence. The introduction of secondary through-space interactions to clusteroluminogens not only enriches their varieties of photophys. properties but also inspires the establishment of novel aggregate photophysics for clusteroluminescence. The results came from multiple reactions, including the reaction of 4-Iodobenzaldehyde(cas: 15164-44-0Recommanded Product: 4-Iodobenzaldehyde)

The title of the article was 《Design, synthesis, and antileukemic evaluation of a novel mikanolide derivative through the Ras/Raf/MEK/ERK pathway》.SDS of cas: 63069-48-7 The author mentioned the following in the article:

Chronic myeloid leukemia (CML) accounts for a major cause of death in adult leukemia patients due to mutations or other reasons for dysfunction in the ABL proto-oncogene. The ubiquitous BCR-ABL expression stimulates CML by activating CDK1 and cyclin B1, promoting pro-apoptotic, and inhibiting antiapoptotic marker expression along with regulations in RAS pathway activation. Thus, inhibitors of cyclins and the RAS pathway by ERK are of great interest in antileukemic treatments. Mikanolide is a sesquiterpene dilactone isolated from several Asteraceae family Mikania sp. plants. Sesquiterpene dilactone is a traditional medicine for treating ailments, such as flu, cardiovascular diseases, bacterial infections, and other blood disorders. It is used as a cytotoxic agent as well. The need of the hour is potent chemotherapeutic agents with cytotoxic effects inhibition of proliferation and activation of apoptotic machinery. Recently, ERK inhibitors are used in clinics as anticancer agents. Thus, in this study, authors synthesized 22-mikanolide derivatives that elucidated to be potent antileukemic agents in vitro. However, a bioactive mikanolide derivative, I, was found with potent antileukemic activity, through the Ras/Raf/MEK/ERK pathway. It can arrest the cell cycle by inhibiting phosphorylation of CDC25C, triggering apoptosis, and promoting DNA and mitochondrial damage, thus suggesting it as a potential chemotherapeutic agent for leukemia patients.

Computed Properties of C2H4I2In 2022 ,《Optimizing functional layer of cation exchange membrane by three-dimensional cross-linking quaternization for enhancing monovalent selectivity》 appeared in Chinese Chemical Letters. The author of the article were Pan, Jiefeng; Zhao, Lei; Yu, Xiaohong; Dong, Jiajing; Liu, Lingling; Zhao, Xueting; Liu, Lifen. The article conveys some information:

Monovalent cation perm-selective membrane (MCPMs) allow fast and selective transport of monovalent cations, and they are promisingly required for extraction of special ions, such as lithium extraction, acid recovery and sea salt production Herein, we report a novel strategy to design the critical functional layers of MCPMs with both space charge repulsion and cross-linked dense screenability. The in-situ deposition polymerization of pyrrole was carried out on the surface of sulfonated polyphenyl sulfone (SPPSU) substrate membrane followed by crosslinking quaternization of the polypyrrole (PPy) layer with diiodinated functional mols., thus, the membrane obtained more excellent selective permeability and stable transport properties of monovalent cations. It confirms that the designed PPy layers with charged surface and crosslinking structure improved the hydrophilicity, facilitated cation transport and increased ion flux. Meanwhile, for the dense PPy layer, the charged cross-linked structure endowed the functional layer with the synergistic characteristics of Donnan exclusion and pore size sieving for pos. charged ions, which improved the monovalent cation perm-selectivity of the membranes. At a constant c.d. of 5.1 mA/cm2, the optimal membrane exhibited superior perm-selectivity (PNaMg = 2.07) and monovalent cation flux (JNa+ = 2.80 x 10-8 (mol cm-2 s-1)) during electrodialysis. After reading the article, we found that the author used 1,2-Diiodoethane(cas: 624-73-7Computed Properties of C2H4I2)
