Mechanical Stretch α‐Cyclodextrin Pseudopolyrotaxane Elastomer with Reversible Phosphorescence Behavior

Advanced Science
Polyethylene glycol chains in two terminals of the naphthalene functional group are threaded into α‐cyclodextrin cavities to form the pseudopolyrotaxane (NPR), which not only effectively induces the phosphorescence of the naphthalene functional group by ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Matrix‐free room‐temperature phosphorescence graphitic carbon nitride quantum dots based on halogen bond interactions for security applications

Nano Select, 2022
Herein, we first designed a one‐step strategy to achieve matrix‐free room temperature phosphorescence (RTP) materials by low temperature solid phase synthesis, using sodium citrate as carbon source and urea as nitrogen source.

Inverting Singlet and Triplet Excited States using Strong Light-Matter Coupling

, 2019
In organic microcavities, hybrid light-matter states can form with energies that differ from the bare molecular excitation energies by nearly 1 eV. A timely question, given recent advances in the development of thermally activated delayed fluorescence ...

Photo‐Responsive Room‐Temperature Phosphorescent Films Exhibiting Photochromism and Time‐Dependent Phosphorescent Colors for Multilevel Anti‐Counterfeiting

Advanced Science, EarlyView.
A series of photo‐responsive polymers are prepared by a facile one‐pot in situ synthesis strategy, where RTP modules and photochromic units are systematically integrated into one polymer system. The triplet‐singlet Förster resonance energy transfer (TS‐FRET) between the donor and acceptor enables the material to exhibit time‐dependent phosphorescence ...

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

Advanced Science, EarlyView.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

Integrated Optoelectronic Model to Predict the External Quantum Efficiency of Single‐Layer TADF Organic Light‐Emitting Diodes

Advanced Electronic Materials, EarlyView.
An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...
