Synaptic Plasticity Powering Long‐Afterglow Organic Light‐Emitting Transistors [PDF]

Advanced Materials, 2021
AbstractLong‐lasting luminescence in optoelectronic devices is highly sought after for applications in optical data storage and display technology. While in light‐emitting diodes this is achieved by exploiting long‐afterglow organic materials as active components, such a strategy has never been pursued in light‐emitting transistors, which are still ...

Photochemical afterglow of single organic molecules with wide‐range tunable lifetime

PhotoMat, EarlyView., 2023
“All‐in‐one” strategy was used to achieve photochemical afterglow in single organic molecule, with second‐to‐hour range tunable lifetime by tailoring the electron‐withdrawing ability of substituents. Abstract Background Photochemical afterglow that relies on slow release of photons from the chemical energy stored by light pre‐irradiation has emerged as

Photoactivation-Enabled Tunable Room-Temperature Phosphorescence and Thermally Activated Delayed Fluorescence in Crystalline Materials. [PDF]

Adv Sci (Weinh)
This work is the first to demonstrate the regulation of photoactivated room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) in crystalline materials without any pretreatment. Furthermore, we reveal the underlying mechanisms by uncovering the role of host‐guest energy level alignment, exciton lifetime, crystallinity,
