Abstract

The emergence of chiral nanomaterials has opened up exciting new avenues for the evolution of advanced optical materials. We first describe the mechanism for the generation of a quadrupole field chirality by permanent magnets, which enables the meticulous assembly of magnetic nanoparticles into long-range chiral superstructures. Then we discuss the design of stimuli-responsive chiral superstructures by transferring chirality to pH-responsive polyaniline, endowing them with the ability for dynamic regulation of their chiroptical properties, including circular dichroism (CD) and optical rotatory dispersion (ORD). Finally, we present the design of chiroptical switches and reconfigurable information encryption systems using these chiral superstructures as building blocks. Collectively, our findings delineate the transformative potential of magnetic assembly in chiral nanomaterial research, promising for advanced optical and biomedical applications.
