Fluorophore Fueled Dynamics: Exploring Adaptive Material Systems
In this project I am investigating the dynamic behavior of materials driven by fuel-induced aggregation. We utilize a modified AIE (Aggregation-Induced Emission) fluorophore that remains soluble in water at pH 7 but aggregates under acidic conditions or upon the addition of a so-called fuel. This aggregation process, facilitated by the formation of active esters with the fuel molecule EDC, is reversible over time.
What sets my research apart is the visualizability of this phenomenon.
The AIE fluorophore exhibits fluorescence upon aggregation, offering real-time insight into material behavior. Through this experimentation, I aim to unravel the mechanisms underlying fuel-induced aggregation and explore potential applications in responsive materials and environmental sensing.
