And the article was published in Chemical Communications (Cambridge, United Kingdom) in 2019. SDS of cas: 2510-22-7 The author mentioned the following in the article:

Hexagonal arrays were fabricated via intermol. halogen bonding between two linear mol. building blocks in a bicomponent blend. The substitution position of the pyridine N atom involved in the halogen bond plays an important role in the formation of the hexagonal structures. The results came from multiple reactions, including the reaction of 4-Ethynylpyridine(cas: 2510-22-7SDS of cas: 2510-22-7)

4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. SDS of cas: 2510-22-7

《Superstructural diversity in salt-cocrystals: higher-order hydrogen-bonded assemblies formed using U-shaped dications and with assistance of π–π stacking》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Yelgaonkar, Shweta P.; Kiani, Daniyal; Baltrusaitis, Jonas; MacGillivray, Leonard R.. COA of Formula: C7H5N The article mentions the following:

Salt cocrystals with components that assemble by hydrogen bonds and aromatic anion-mol. stacks (π–π stacks) are reported. U-shaped bipyridines and an isocoumarin carboxylic acid self-assemble to form 5-, 6-, and 10-component aggregates with components in double and quadruple face-to-face stacks. DFT calculations support the π–π stacks to help stabilize the salt cocrystals. The experimental part of the paper was very detailed, including the reaction process of 4-Ethynylpyridine(cas: 2510-22-7COA of Formula: C7H5N)

4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.COA of Formula: C7H5N

In 2019,Chemical Communications (Cambridge, United Kingdom) included an article by Ragupathi, Ayyakkannu; Sagadevan, Arunachalam; Charpe, Vaibhav Pramod; Lin, Chun-Cheng; Hwu, Jih-Ru; Hwang, Kuo Chu. Reference of 4-Ethynylpyridine. The article was titled 《Visible-light-driven copper-catalyzed aerobic oxidative cascade cyclization of N-tosylhydrazones and terminal alkynes: regioselective synthesis of 3-arylcoumarins》. The information in the text is summarized as follows:

Regioselective green synthesis of 3-arylcoumarins I [R1 = H, 6-Me, 6-Br, etc.; R2 = H, 3-MeOC6H4, 4-Py, etc.; R3 = H, Me, Ph] as sustainable process was carried out via visible-light-driven copper catalyzed aerobic oxidative cascade cyclization of N-tosylhydrazones with terminal alkynes. This operationally simple methodol. was successfully proceeded well to afford biol. active compounds, such as monoamine oxidase B inhibitor I [R1 = 6-Me; R2 = 3-MeOC6H4; R3 = H] and horseradish peroxidase inhibitor I [R1 = 6-OH; R2 = 2-HOC6H4; R3 = H] in satisfactory yields under mild conditions. In the experiment, the researchers used many compounds, for example, 4-Ethynylpyridine(cas: 2510-22-7Reference of 4-Ethynylpyridine)

4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Reference of 4-Ethynylpyridine

The author of 《Emissions from a triphenylamine-benzothiadiazole-monocarbaborane triad and its applications as a fluorescent chemosensor and a white OLED component》 were Peng, Zhixing; Zhang, Kang; Huang, Zongwei; Wang, Zaibin; Duttwyler, Simon; Wang, Yanguang; Lu, Ping. And the article was published in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2019. Recommanded Product: 4-Ethynylpyridine The author mentioned the following in the article:

A fluorescent D-A-D’ triad (1), composed of monocarbaborane, benzothiadiazole and triphenylamine, was synthesized. By replacing monocarbaborane with Ph, p-methoxyphenyl (PMP), or 4-pyridinyl (Py), 3 analogs were prepared for comparison. Monocarbaborane is an electron donating group based on the comparative anal. of NMR spectra and the systematic study of their photophys. properties. Triad 1 emits bright-yellow light in THF solution with the highest quantum yield and the longest decay time among these compounds It tends to form nanoparticles in aqueous THF solution The in situ generated nanoparticles might be used to detect Ag ions with high sensitivity and high selectivity. By holding the mols. via multiple CH···π interactions and electrostatic forces between the Et4N+ cation and the cage, a sheet-like arrangement of 1 is formed in the solid state with the smallest crystal d. that provides the maximum possibility of mechanofluorochromism from the crystalline to the ground form. By doping 1 in PVK, a white OLED is obtained. Crystallog. data are given. In the experimental materials used by the author, we found 4-Ethynylpyridine(cas: 2510-22-7Recommanded Product: 4-Ethynylpyridine)

4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Recommanded Product: 4-Ethynylpyridine
