In 2022,Nitisha; Chetti, Prabhakar; Parthasarathy, Venkatakrishnan published an article in Chemical Communications (Cambridge, United Kingdom). The title of the article was 《Coronene-embedded ‘super’ coumarins》.Electric Literature of C5H6O2 The author mentioned the following in the article:
A non-planar π-enlarged coronene-embedded coumarin achieved via pyranone annulation and its cyanated derivative possess bright orange to red emission in both solution and solid states, with scope for bioimaging applications. The multiple redox states, frontier MO energy levels and strong cofacial π-stacking ability point towards applications in organic optoelectronics. In addition to this study using Ethyl propiolate, there are many other studies that have used Ethyl propiolate(cas: 623-47-2Electric Literature of C5H6O2) was used in this study.
Ethyl propiolate(cas: 623-47-2) is a clear colorless to pale yellow liquid that is soluble in ethanol, ether and chloroform. It an important organic chemical raw material and pharmaceutical intermediate. Ethyl propargylate is obtained by oxidation of propargyl alcohol to propargylic acid followed by esterification.Electric Literature of C5H6O2
