Abstract
Conjugated polymer nanoparticles (CPNs) harvest energy from photons and transfer it efficiently to dye molecules in their proximity. My research focuses on a kind of photochromic dye that harnesses the transferred energy to perform its photochromic conversion, resulting in fluorescence switching of the CPN. My system features PFBT nanoparticles and a class of merocyanine dyes. The fluorescence of the system can be activated and detected using single color visible light by modulating the energy transfer pathway between the CPN and the dye. Kinetic analysis and modeling explains the accelerated fluorescence switching observed in the system, producing new insights that will both contribute to more structural understanding of similar systems and lead to potential applications that harness similar effects.
