The Department of Applied Chemistry at the University of Debrecen has discovered and developed a molecule with fluorescent properties as a substitute for the widely used fluorescent dye Prodan. Various modifications have been made to the main molecule to impart useful properties for a wide range of applications, including substitutions with hydroxyl-ester, alkyl, and acrylate groups. The photoluminescence behavior of each of these derivatives has been studied in a variety of solvents, covering three main characteristics: polarity, acidity, and basicity, to establish their absorption-emission range and effectiveness in emitting light in the visible spectrum.
