Herein the synthesis of siloxane-functionalized CBP mols. (4,4′-bis(carbazole)-1,1′-biphenyl) for liquid optoelectronic applications was reported. The room-temperature liquid state was obtained through a convenient functionalization of the mols. with heptamethyltrisiloxane chains via hydrosilylation of alkenyl spacers. The synthesis comprised screening of metal-catalyzed methodologies to introduce alkenyl linkers into carbazoles (Stille and Suzuki Miyaura cross-couplings), incorporated the alkenylcarbazoles to dihalobiphenyls (Ullmann coupling), and finally introduced the siloxane chains. The used conditions allowed the synthesis of the target compounds, despite the high reactivity of the alkenyl moieties bound to π-conjugated systems toward undesired side reactions such as polymerization, isomerization, and hydrogenation. The features of these solvent-free liquid CBP derivatives made them potentially interesting for fluidic optoelectronic applications.3,6-Dibromo-9H-carbazole(cas: 6825-20-3Quality Control of 3,6-Dibromo-9H-carbazole) was used in this study.
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used in the preparation of N-(2-hydroxyethyl)-3,6-dibromocarbazole.Quality Control of 3,6-Dibromo-9H-carbazole
