In 2022,Virgili, Tersilla; Ganzer, Lucia; Botta, Chiara; Squeo, Benedetta Maria; Pasini, Mariacecilia published an article in Molecules. The title of the article was 《Asymmetric AZA-BODIPY with Optical Gain in the Near-Infrared Region》.Synthetic Route of C6H6OS The author mentioned the following in the article:
In recent years, there has been a lot of interest in the development of organic compounds emitting in the near-IR (NIR) region due to their stimulating applications, such as biosensing and light detection and ranging (LiDAR). Moreover, a lot of effort has been devoted to finding organic emitters with optical gain in the NIR region for lasing applications. In this paper, we present the ultrafast spectroscopy of an asym. AZA-BODIPY mol. that shows relevant photophys. changes moving from a diluted solution to a concentrated solution and to a spin-coated film. The diluted solution and the spin-coated film show a bleaching band and a stimulated emission band in the visible region, while the very concentrated solution displays a broad (150 nm) and long-living (more than 400 ps) optical gain band in the NIR region, centered at 900 nm. Our results pave the way for a new organic laser system in a near-IR spectral region. The results came from multiple reactions, including the reaction of 1-Thiophen-2-yl-ethanone(cas: 88-15-3Synthetic Route of C6H6OS)
1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Specialized thiophenes can be synthesized similarly using Lawesson’s reagent as the sulfidizing agent, or via the Gewald reaction, which involves the condensation of two esters in the presence of elemental sulfur. Another method is the Volhard–Erdmann cyclization. Synthetic Route of C6H6OS
