Enhanced light emission from top-emitting organic light-emitting diodes by optimizing surface plasmon polariton losses [PDF]
, 2015 We demonstrate enhanced light extraction for monochrome top-emitting organic light-emitting diodes (OLEDs). The enhancement by a factor of 1.2 compared to a reference sample is caused by the use of a hole transport layer (HTL) material possessing a low ...

Acta Crystallographica Section E Structure Reports Online, 2011 The molecule of the title pyridine derivative, C(5)H(6)N(2)O, shows approximate C(s) symmetry. Intra-cyclic angles cover the range 118.34 (10)-123.11 (10)°. In the crystal, O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds connect the mol-ecules into double layers perpendicular to the a axis. The shortest centroid-centroid distance between two π-systems is 3.8887 (

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?
Advanced Materials, EarlyView.The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Advanced Materials, EarlyView.ABSTRACT The optoelectronic performance of organic light‐emitting diodes (OLEDs) is critically governed by charge injection from electrodes into organic layers, where significant energy barriers at the interfaces often impede efficient charge injection.

Advanced Materials, EarlyView.A hybridized charge‐transfer window combining short‐range and long‐range charge transfer is realized within a fully conjugated multi‐resonance thermally activated delayed fluorescence framework. The resulting excited‐state hybridization minimizes the singlet–triplet energy gap (0.04 eV) and enables ultrafast reverse intersystem crossing (krISC = 2.1 ...

Advanced Materials Interfaces, EarlyView.A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to
