Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.

Chiral benzimidazoles as hydrogen bonding organocatalysts [PDF]

, 2015
Several bifunctional organocatalysts bearing the benzimidazole unit have been designed in order to act as bifunctional systems by hydrogen bonding. Chiral 2-aminobenzimidazoles are conformational rigid guanidines able to catalyze enantioselectively ...

Boosting Organic Long Persistent Luminescence by Enhancing Charge Separation Processes in Three‐Component Systems

Advanced Science, EarlyView.
Electron donor TMB is introduced into BF2bdk‐PhB system to enhance charge separation process. The resultant three‐component materials exhibit visible‐light‐excitable OLPL afterglow lasting for several hours under ambient environment, with OLPL efficiency of ≈10% and display OLPL brightness comparable to inorganic materials.

Assembling Hexahedral Supramolecular Nano‐Aggregates on Rice Wax Layer Matrices to Promote the Leaf Deposition and Bioavailability of Bactericides for Plant Protections

Advanced Science, EarlyView.
To address the problem of off‐target movement and low bioavailability of pesticides, two anisotropic supramolecular building units (BiTA18@β‐CD and BiTA18@γ‐CD) have been invented that can self‐assemble into nano‐sized hexagonal cuboids on the rice microcrystalline matrix. This manipulation realizes the enhanced utilization of bactericides for rice and

Determination of the Kinetic Rates and Intrinsic Nonradiative Losses in Organic Thermally Activated Delayed Fluorescence Emitters

Advanced Science, EarlyView.
It is demonstrated that the kinetic rates and intrinsic nonradiative losses of purely organic emitters with thermally activated delayed fluorescence cannot be precisely determined by photoluminescent measurements alone. With device modeling, it is then possible to quantify the absolute nonradiative losses from singlets and triplets, and therefore the ...
