Noncovalent functionalization of graphene with pyrene-terminated liquid crystalline polymer was written by Ji, Liangliang;Wu, Yanhong;Ma, Lijun;Yang, Xiaoming. And the article was included in Composites, Part A: Applied Science and Manufacturing in 2015.COA of Formula: C18H11BrO The following contents are mentioned in the article:
Pyrene-terminated liquid crystalline polymers, poly[8-(4-cyano-4′-biphenyl)-1-octanoylacrylate] and poly[6-(4-cyano-4′-biphenyl)-1-hexanoylacrylate] were synthesized and used to functionalize graphene sheets via π-π interactions. The resulting liquid crystalline polymers functionalized graphene sheets were characterized by UV-vis spectroscopy, fluorescence spectroscopy, thermal gravimetric anal., Fourier transform IR spectroscopy, X-ray diffraction, at. force microscopy and Raman spectroscopy. It was found that an intercalated layer structure was formed when polymer was grafted onto graphene sheets. The liquid crystalline polymers were able to effectively disperse graphene in N,N-dimethylformamide that were stable for months. Addnl., a remarkable smaller distance of adjacent mesogenic units was observed, which is attributed to the confinement of the polymer chains between 2D reduced graphene oxide sheets. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5COA of Formula: C18H11BrO).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
