In 2019,Beilstein Journal of Nanotechnology included an article by Jana, Achintya; Mishra, Puneet; Das, Neeladri. SDS of cas: 15854-87-2. The article was titled 《Polymorphic self-assembly of pyrazine-based tectons at the solution-solid interface》. The information in the text is summarized as follows:
The synthesis and surface self-assembly of a new pyrazine-derived mol. with pyridine pendants I was reported. Ambient scanning tunneling microscopy investigation at the solution-solid interface revealed polymorphic self-assembly of these mols. on a HOPG substrate. Two different mol. packing structures with equal distribution were observed Detailed anal. of the STM images emphasized the crucial role of weak intermol. hydrogen bonding, and mol.-substrate interactions in the formation of the observed polymorphs. Such weak hydrogen bonding interactions were highly desirable for the formation of modular supramol. architectures since they could provide sufficiently robust mol. structures and also facilitate error correction. The experimental process involved the reaction of 4-Iodopyridine(cas: 15854-87-2SDS of cas: 15854-87-2)
4-Iodopyridine(cas: 15854-87-2) 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.SDS of cas: 15854-87-2
