Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions

open access: yesAdvanced Optical Materials, EarlyView.
Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.
