Modulating TTA efficiency through control of high energy triplet states Open
It is shown here that positional isomerism of perylene substitution affects high energy triplet states differently. This in turn influences the quantum efficiency of triplet–triplet annihilation photon upconversion.

Exciton Delocalization Counteracts the Energy Gap: A New Pathway toward NIR-Emissive Dyes Open
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 the excited state energy, allowing for emission well int…

Vitrification of octonary perylene mixtures with ultralow fragility Open
Mixtures of similar molecules can display an ultralow fragility, which facilitates the design of strong organic glass formers.

Multiplicity conversion based on intramolecular triplet-to-singlet energy transfer Open
We demonstrate conversion of an excited triplet state to an excited singlet state through resonance energy transfer.
