One-dimensional optoelectronic nanostructures derived from the aqueous self-assembly of π-conjugated oligopeptides was written by Diegelmann, Stephen R.;Gorham, Justin M.;Tovar, John D.. And the article was included in Journal of the American Chemical Society in 2008.COA of Formula: C7H8O2S This article mentions the following:
The aqueous self-assembly of oligopeptide-flanked π-conjugated mols. into discrete one-dimensional nanostructures is described. Unique to these mols. is the fact that the π-conjugated unit has been directly embedded within the peptide backbone by way of a synthetic amino acid with π-functionality that is compatible with standard Fmoc-based (Fmoc = 9-fluorenylmethoxycarbonyl) peptide synthesis. The peptide-based mol. design enforces intimate π-π communication within the aggregate after charge-screening and self-assembly, making these nanostructures attractive for optical or electronic applications in biol. environments. The synthesis and assembly are reported along with spectroscopic and morphol. characterization of the new nanomaterials. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9COA of Formula: C7H8O2S).
Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.COA of Formula: C7H8O2S
