In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Main-chain liquid crystalline polymers bearing periodically grafted folding elements, published in 2021, which mentions a compound: 50816-19-8, Name is 8-Bromooctan-1-ol, Molecular C8H17BrO, Electric Literature of C8H17BrO.
A series of main-chain liquid crystalline polymers (MCLCPs) carrying a biphenyl mesogen and a flexible alkylene spacer in the backbone was prepared; a unique feature of these polymers is that they have a non-mesogenic pendant segment, namely, an alkyl, PEG or fluoroalkyl segment, which is periodically located along the backbone. Due to the presence of these periodic substituents, the chain folds in a zigzag fashion, permitting the collocation of the mesogenic biphenyl units within one layer and the pendant segments in alternate layers of a lamellar morphol. generated by these polymers. Most of the polymers were found to exhibit a stable smectic mesophase upon melting that appears to retain the folded chain conformation, which becomes disordered only after the isotropization transition. From the variation of the interlamellar spacing, estimated from SAXS studies, as a function of the pendant alkyl segment length, it was evident that the pendant segments adopted an extended all-trans conformation and these were fully interdigitated. Furthermore, by comparing the d-spacing of a sample that had longer alkylene backbone segments (C10 instead of C6), we were able to show that the linear variation remains valid for an increase in both the length of the pendant alkyl chain as well as that of the backbone alkylene segment. This observation serves as further evidence for the zigzag folded chain conformation adopted by this class of periodically substituted MCLCPs. Furthermore, the study also reveals the role of aromatic mesogens in enhancing the propensity to adopt this conformation and attain lamellar morphologies, wherein the dimensions are regulated by only the grafting d. and the grafted segment length and not by the mol. weight of the polymer.
After consulting a lot of data, we found that this compound(50816-19-8)Electric Literature of C8H17BrO can be used in many types of reactions. And in most cases, this compound has more advantages.
