Detecting the Six Polytypes of Five‐Layer Graphite

open access: yesAdvanced Materials, EarlyView.
The six possible periodic crystals—so‐called polytypes of Penta layer graphene are identified using Raman, second harmonic, and electric surface potential measurements. The measurements reveal the polytypes’ abundance, relative stability, and annihilation dynamics, crucial for future multiferroic SlideTronic applications.

Pyridocarbene‐Based Tetradentate Pt(II) Complexes for Long Device Lifetime over 500 h in Blue Phosphorescent Organic Light–Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
Pt‐impy and Pt‐Me‐impy exhibit external quantum efficiencies of 24.5% and 27.4% at the 3 wt.% doping concentration, respectively. In particular, Pt‐impy and Pt‐Me‐impy doped blue PhOLEDs optimized for stability demonstrate a device lifetime of up to 95% of the initial luminance of 543 and 228 h at 1000 cd m−2, which has never been achieved in the blue ...
