Origin of Enhanced Efficiency and Reduced Roll‐Off in Organic Light‐Emitting Diodes Based on Pt(II) Complexes

Advanced Science, EarlyView.
Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

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

Advanced 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 ...

Simultaneous Emission AC-OLED Pixel Circuit for Extended Lifetime of OLED Display

IEEE Journal of the Electron Devices Society, 2018
This paper demonstrates a pixel circuit of seven thin film transistors (TFTs) and two capacitors that drives an AC driven OLED (AC-OLED) at a simultaneous emission scheme. Because the AC-OLED is composed of two OLED units connected in opposite directions,
