Energy‐Transfer‐Driven Programmable Luminescence in Bi3+‐Eu3+ Co‐Doped Na3Ca2TaO6 Phosphors Toward Multifunctional Optical Applications

Advanced Optical Materials, EarlyView.
Energy transfer from broadband Bi3+ sensitizers to Eu3+ emitters enables composition‐, excitation‐, and temperature‐dependent luminescence in Na3Ca2TaO6. These controllable optical states support ratiometric thermometry and excitation‐selective, filter‐assisted information decoding in flexible phosphor–polydimethylsiloxane films, demonstrating how ...

Tailoring Amine Substitution in Fluorene and Dibenzothiophene: A Molecular Strategy for Ultralong Organic Phosphorescence

Advanced Optical Materials, EarlyView.
Tailored amine substitution in fluorene and dibenzothiophene derivatives enables systematic control of excited‐state properties and triplet population. Combined photophysical studies, TD‐DFT calculations and time‐resolved EPR reveal how charge‐transfer character, sulfur‐induced spin–orbit coupling and triplet manifold engineering cooperate to promote ...

Regioselective π‐Extension of Helical PAHs: Tuning Energy Gaps and Excited‐State Dynamics Directed by Clar's Sextet Migration

Advanced Optical Materials, EarlyView.
Central and terminal ring fusions of per‐peri‐perbenzo[7]helicene (PB[7]H) yield novel helical polycyclic aromatic hydrocarbons (HPAHs). The migration of Clar's aromatic sextets governs the inner‐rim stiffness. This topology‐directed strategy bridges the discrete optical gaps of homologous series. Transition moment density (TMD) analysis visualizes the

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...
