Highly‐Emissive Organic Photovoltaics Approaching Theoretical Limit Voltage and Enabling Multifunctional Energy‐Harvesting Displays

Advanced Materials, EarlyView.
A highly‐emissive organic photovoltaic employs donor–acceptor pairs with alternately localized frontier molecular orbitals, preserving high triplet energies and small reorganization energies to suppress non‐radiative recombination. As a result, it exhibits a high open‐circuit voltage approaching the Shockley–Queisser limit and a high ...

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

Advanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

Advanced Materials Technologies, EarlyView.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across

Materials for Suppressed Triplet‐Polaron Quenching in Efficient and Long‐Lifetime Phosphorescent OLEDs

Advanced Optical Materials, EarlyView.
We performed a computational screening of phosphorescent emitters and charge transporters for OLEDs to identify combinations that minimize triplet‐polaron quenching, a major cause of efficiency loss and short operational lifetimes, especially in blue OLEDs. Our results reveal key design rules and highlight emitter‐transporter pairs that strongly reduce

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces
Photon interconversion in semiconductors is of fundamental importance for digital imaging and quantum sensing. Nonlinear processes such as triplet–triplet annihilation (TTA) offer photon upconversion (UC) at yields desired for solid‐state optoelectronic ...
