energy. This has been utilized in light sources, displays, bioimaging, and advanced sensors. Organic ML materials are strongly limited to application by in situ unrepeatable ML. Now, in situ solar‐renewable organic ML materials can be formed by introducing a soft alkyl chain into an ML unit. For the firsttime, the ML from these polycrystalline thin films can be iteratively produced by simply recrystallizing
Mechanoluminescence (ML) materials are attracting increasing interest due to its promising applications in various areas. However, to date, it remains a major challenge to develop a precise and universal route to achieving organic ML materials. Herein, we report the first example that ML can be easily realized in organic piezophotonic host-guestcrystals, under the conditions that neither the host
Compounds displaying delayedfluorescence (DF), from severe concentration quenching, have limited applications as nondoped organic light‐emitting diodes and material sciences. As a nondoped fluorescent emitter, aggregation‐induced emission (AIE) materials show high emission efficiency in their aggregated states. Reported herein is an AIE‐active, DF compound in which the molecular interaction is modulated

Aggregation-induced emission (ATE) type thermally activated delayed fluorescent (TADF) emitters were developed by asymmetric substitution of donor moieties to a diphenylsulfone acceptor. The AIE properties of the TADF emitters increased the quantum efficiency of the non-doped TADF devices and asymmetric substitution was more effective than symmetric substitution to enhance the quantum efficiency of the non-doped devices.
