Kobe University researchers engineered a tri-anthracene molecule around a boron center enabling a 20% faster upconversion rate by facilitating rapid triplet exciton hopping among anthracene units. Published in Angewandte Chemie International Edition, this molecular hopscotch mechanism enhances efficiency and tunability of low-energy to high-energy photon conversion, with applications in solar energy harvesting, medical imaging, and sensing technologies.
