Abstract:

My research seeks to unlock the potential of organic electronics at the nanoscale, creating materials which rival the complexity and function of macroscale devices on single nanoparticles. Using orthogonal polymerization techniques, I have prepared multiblock bottlebrush polymers from distinct organic semiconductors, giving ordered structures mimicking multilayer OLEDs and nanoscale RGB pixels. By quantifying changes in energy transfer efficiency in these systems, I have shown that these materials can act as polarity-sensitive fluorescent inks for encryption and encoding. My work has also addressed problems in closely related fields, including the efficient synthesis of planar TADF materials and ultrastable organic fluorophores.
