The Photophysics of All-Trans Para-Distyrylbenzene

The Photophysics of All-Trans Para-Distyrylbenzene. The present Perspective critically re-examines the photophysics of para-distyrylbenzene (DSB) as a prototype of herringbone-arranged H-aggregates to resolve the apparent contradiction of the frequently reported "aggregation-induced emission quenching" in H-aggregates on one side and highly emissive DSB crystals on the other and discusses the signatures and fate of excitons in single- and polycrystalline samples...
