Abstract:

Over the past decade, thermally activated delayed fluorescence (TADF) materials have become central to optoelectronics research due to their ability to harvest triplet excited states for efficient displays, while being fully organic chromophores. Our group, however, has expanded their use beyond traditional display technology. In this talk, I will cover the design of TADF materials in both small molecules and polymers, as well as their applications in photocatalysis, including energy transfer and photoredox modes. Judicious design strategies, such as molecular rigidification, heteroatom doping, and regioisomeric isomerization, will be discussed. Finally, I will highlight their potential as photo-clickable chromophores for surface modification of fully organic nanoparticles.
