The oxidative dimerization of 2-alkyl-3-hydroxy-1-phenalenones, the nitrogen-free carbon homologs of N-alkylnaphthalimides, was achieved using cesium hydroxide. This opens access to a new class of intensely long-wavelength absorbing perylenic dyes that adopt columnar liquid-crystalline structures at ambient temperature and that are obtained as separable pairs of centrosym. (transoid) and polar (cisoid) regioisomers. Their light absorption and mesomorphic properties make these compounds promising materials for organic opto-electronics. In the experiment, the researchers used many compounds, for example, Diethyl isobutylmalonate (cas: 10203-58-4Related Products of 10203-58-4).
Diethyl isobutylmalonate (cas: 10203-58-4) 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.Related Products of 10203-58-4
