One‐Step Intermolecular Oxidative Coupling and Cyclodehydration Strategy for Pure‐Green B,N,O‐Embedded Hetero[9]Helicene Emitter

ABSTRACT Helicenes are promising circularly polarized luminescence (CPL) candidates owing to their inherent chirality. In particular, B,N‐embedded heterohelicenes achieve superior exciton utilization via multiple‐resonance thermally activated delayed fluorescence, whereas their s...

Design of a bionic flapping wing mechanism based on RSSR mechanism and analysis of aerodynamic characteristics

Abstract Flapping-wing aircraft have broad application prospects in scientific research and engineering. Based on the spatial offset RSSR mechanism, this paper designs a bionic flapping-wing structure. By deriving the kinematic equations of the mechanism and taking the preset fla...
