High‐Efficiency TADF Dendritic Emitters Enabled by Synchronously Inhibiting Degenerated Triplet Excited States and Structural Relaxation Toward Solution‐Processed OLEDs with EQE Over 33%

Advanced Science, EarlyView.
Asymmetrical thermally activated delated fluorescence dendritic emitters are delicately constructed through symmetry breaking strategy, and near‐unity photoluminescence efficiency and excellent reverse intersystem crossing process are achieved via breaking the degeneracy of vibrational levels and boosting the spin flip of triplet excitons.

Aggregation‐Induced Resonance Energy Transfer in Polymer Dots to Boost Electrochemiluminescence Performance for Bioimaging of Glycan on Cells

Advanced Science, EarlyView.
This study pioneers an aggregation‐induced resonance energy transfer mechanism by synergistically integrating aggregation‐induced emission (AIE), resonance energy transfer (RET), and thermally activated delayed fluorescence (TADF) within co‐reactant conjugated polymers to develop self‐enhanced ECL emitters, which achieves an ECL efficiency up to 92.6 ...

Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

Advanced Electronic Materials, EarlyView.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.
