Abstract Strong light-matter coupling provides the means to challenge traditional rules of chemistry. In particular, an energy inversion singlet and triplet excited states would be fundamentally remarkable since it violate classical Hund’s rule. An organic chromophore possessing a lower state can effectively harvest dark states, thus enabling 100% internal quantum efficiency in electrically pumped light-emitting diodes lasers. Here we demonstrate unambiguously prototype molecule by strong...

Exciton coupling between the transition dipole moments of ordered dyes in supramolecular assemblies, so-called J/H-aggregates, leads to shifted electronic transitions. This can lower excited state energy, allowing for emission well into near-infrared regime. However, as we show here, it is not only energy modifications that J-aggregates provide. A bay-alkylated quaterrylene was synthesized, which found form 1,1,2,2-tetrachloroethane. combination superradiance and a decreased nonradiative...

Unlearnable examples (UEs) seek to maximize testing error by making subtle modifications training that are correctly labeled. Defenses against these poisoning attacks can be categorized based on whether specific interventions adopted during training. The first approach is training-time defense, such as adversarial training, which mitigate effects but computationally intensive. other pre-training purification, e.g., image short squeezing, consists of several simple compressions often...
