Julolidine is widely used in the field of organic electronics and optoelectronics due to its unique electronic properties. It serves as a key building block in the synthesis of organic dyes and pigments, particularly those used in sensitizers for dye-sensitized solar cells (DSSCs). Its rigid structure and electron-donating characteristics make it suitable for enhancing light absorption and charge transfer efficiency in these applications. Additionally, julolidine derivatives are employed in the development of fluorescent probes and sensors for detecting metal ions and biomolecules, owing to their strong fluorescence and stability. In material science, it is utilized in the creation of organic light-emitting diodes (OLEDs) and nonlinear optical materials, contributing to advancements in display technologies and photonic devices.
