Photoactivated room temperature phosphorescence from lignin [PDF]

Nature Communications
Sustainable photoactivated room temperature phosphorescent materials exhibit great potential but are difficult to obtain. Here, we develop photoactivated room temperature phosphorescent materials by covalently attaching lignin to polylactic acid, where ...

Precisely Regulating 2.45 s Pure Blue Room-Temperature Phosphorescence via Supramolecular Coordination. [PDF]

Adv Sci (Weinh)
Herein, a pure deep blue room‐temperature phosphorescence (415 nm) with lifetime up to 2.45 s is successfully achieved by a covalently crosslinking purely organic material based on boric acid (BA) and 3,5‐dicarboxyphenylboronic acid (BOP) through a simple dehydration reaction, which can be adjusted precisely by supramolecular coordination with ...

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,
