WebHemithioindigo compounds are attractive two-way molecular photoswitches combining stilbene and thioindigo parts connected by a C–C double bond. In solution, these photoswitches have been well studied. This study presents the investigation of a hemithioindigo derivative in the gas phase. Visible absorption sp 2024 PCCP HOT Articles WebDibenzo[b, f]oxepine derivatives are an important scaffold in natural, medicinal chemistry, and these derivatives occur in several medicinally relevant plants. Two dibenzo[b, f]oxepines were selected and connected with appropriate fluorine azobenzenes. In the next step, the geometry of E/Z isomers was analyzed using density functional theory (DFT) calculations.
