Near‐Infrared Light‐Directed Handedness Inversion in Plasmonic Nanorod‐Embedded Helical Superstructure

A self-organized helical superstructure impregnated with unique mesogen-modified plasmonic nanorods is found to exhibit handedness inversion upon NIR irradiation, resulting from the significant “photothermal effect” of embedded gold nanorods. The reverse process occurs upon removal of the light exposure. Furthermore, NIR light-directed circularly polarized dynamic reflections with opposite chirality through the visible range spanning the red, green, and blue (RGB) wavelengths are, for the first time, demonstrated.
