A Portable Optical Sensor for Real-time Absorbance Characterization of Tunable Anthracene-Endoperoxides

Inhalt:
Anthracene Endoperoxide (ANT-EPO) molecules exhibit a unique ability to selectively bind and release oxygen, making them promising candidates for energy storage applications. This work focuses on developing a sensing system to monitor the continuous binding and release of oxygen by ANT-EPO molecules, enabling efficient energy storage systems capable of releasing energy on demand. The sensing method involves an integrated optical sensor utilizing a 265 nm deep-UV light-emitting diode (LED) to stimulate ANT-EPO at its absorption peak, along with measuring and reference photodiodes for precise absorbance measurements. Experimental runs were focused on monitoring and tracking absorbance change over time, providing valuable data on the dynamics of oxygen release and laying the foundation for the innovative optical detection system. By focusing on real-time measurements and calibration procedures, this research aims to contribute to a better understanding of ANT-EPO behaviour and its potential applications in energy storage systems. The developed sensor opens possibilities for advancing adaptable energy technologies, enabling systems to adjust their reactions based on available energy. This paves the way towards future applications in materials systems, where state changes are triggered only when sufficient energy is available.
