Researchers Sunghan Kim, Youngmin You, and their team have developed innovative organic molecules capable of harvesting excitons, as detailed in their article number 1900630. By exploiting the non-bonding orbital, they enable the efficient conversion of triplet excitons into singlet excitons. This conversion leads to the production of efficient, medium-tolerant blue fluorescence emission without any delayed emission components. This strategy presents a promising alternative to current electroluminescence principles, allowing for rapid harvesting of triplet excitons and avoiding hazardous annihilation processes.-Journal cover picture by scapiens
