TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

Angewandte Chemie, EarlyView.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Tuning Steric Hindrance and Intermolecular Interactions in Tetrahydroindolocarbazoles for Dual Thermally Activated Delayed Fluorescence and Room‐Temperature Phosphorescence

ChemistryEurope
Synthesizing organic luminescent materials exhibiting long‐lived afterglow at room temperature, through room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF), properties in pure organic derivatives remains a challenge,

Photoactivation‐Enabled Tunable Room‐Temperature Phosphorescence and Thermally Activated Delayed Fluorescence in Crystalline Materials

Advanced 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,

Fluorene‐Framework Engineering Enables Narrowband Red Multi‐Resonance Emitters for High‐Efficiency With Negligible Roll‐Off Toward BT.2020

Angewandte Chemie, EarlyView.
σ‐Decoupled C9 fluorene‐framework topology control enables narrowband red MR emitters. SF‐BNO and PF‐BNO share the same BNO core, but differ in closed/open fluorene ring closure. SF‐BNO improves steric shielding and stability, while PF‐BNO enhances PLQY, orientation, and efficiency. Ex‐PSF and TE‐OLED architectures deliver ultra‐low efficiency roll‐off

Smartphone‐Guided Visible Light Modulation of RSNOs for Antimicrobial Activity via Controlled Nitric Oxide Release

Advanced Science, EarlyView.
A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...
