Helical Photonic Confinement of Metal Clusters Enables Switching and Imaging of Near‐Infrared Circularly Polarized Light
clusters undergo reversible assembly-disassembly within helical nanochannels, allowing controllable NIR-CPL switching and handedness inversion. Mechanistic studies confirm that the CPL enhancement originates from chiral photonic propagation modulation rather than intrinsic emitter chirality. This helical-confinement principle is extendable to multicolor metal clusters, offering a general route toward high-efficiency CPL materials.
