标 题:Facile synthesis of a series of liquid crystalline 2-(4′-alkylphenyl)-5-cyanopyridines

摘要:The invention relates to a facile synthesis of a series of 2-(4′-alkylphenyl)-5-cyanopyridine liquid crystal compounds which are represented by the following formula (I): n nwherein C n is a linear alkyl having 1-12 carbon atoms. The synthesis of the liquid crystalline 2-(4′-alkylphenyl)-5-cyanopyridine is completed in a two-step reaction. First, a Grignard reagent (such as 4-alkylphenylmagnesium bromide) is added to a 3-cyanopyridinium salt (such as N-phenyloxycarbonyl-3-cyanopyridinium chloride) to get a 1,2-dihydropyridine. Then the 1,2-dihydropyridine is oxidized with o-chloronil to obtain the 2-(4′-alkylphenyl)-5-cyanopyridine.

摘要:Methods are provided for fabricating functional nanostructures (e.g., nanowires/nanofibers) via chemical vapor deposition polymerization of paracyclophanes or substituted paracyclophanes onto and through a structured fluid, such as a film of liquid crystals, on a substrate. A one-step process is provided that does not require the use of any solid templates, nor does it require any volatile solvents, additives or catalysts. The resulting nanowires/nanofibers can be in the form of aligned nanowires/nanofibers arrays supported on any solid material, in the form of nanofibers mats supported on porous materials, or as individual free-standing nanowires/nanofibers. By using chiral liquid crystals, chiral nanofibers can be fabricated. The functional nanowires/nanofibers can contain one or more type of surface reactive groups that allows for post surface chemical modifications on the nanowires/nanofibers. Such nanostructures can be used in a range of different applications, including in biomedical applications.
