Supramolecular Terbium‐Threonine Chiral Emitters with Tunable Circularly Polarized Luminescence as Anticounterfeiting‐Ink for Autonomous Data Encryption

open access: yesAdvanced Science, EarlyView.
A one‐pot, aqueous, and scalable method for synthesizing chiral lanthanide supramolecular emitters using terbium and threonine is reported. The aqueous solution of these chiral emitters displays the following features: (i) 100 % transparency, (ii) tunable luminescence and CPL, and (iii) a pH feedback loop that controls the “on‐off” states of ...

Aggregation‐Controlled Triplet Exciton Regulation Enables Single‐Emitter Color‐Evolving Afterglow

open access: yesAdvanced Science, EarlyView.
A single‐emitter system based on DTP‐R luminophores enables time‐evolving afterglow through aggregation‐regulated excited‐state dynamics. The coexistence and suppression of delayed fluorescence and phosphorescence are controlled via concentration tuning and host‐guest engineering, revealing the RISC origin of delayed fluorescence and enabling ...

Precisely Regulating 2.45 s Pure Blue Room‐Temperature Phosphorescence via Supramolecular Coordination

open access: yesAdvanced Science, EarlyView.
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

open access: yesAdvanced Science, EarlyView.
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,
