Exploring the Circular Polarization Capacity from Chiral Cellulose Nanocrystal Films for a Photo-Controlled Chiral Helix of Supramolecular Polymers

Mingcong Xu et al.

Summary: The circular polarization capacity of chiral cellulose nanocrystal (CNC) films is demonstrated here to trigger the photo-alignment of achiral supramolecular polymers into helical structures. The chiral induction effect of circularly polarized light (CPL) is enhanced on polymers with longer spacers. Combining carbon dots with CNC films enables CPL emission with a considerable luminescence dissymmetry factor, which can be used for the photo-alignment of supramolecular polymers with high chiroptical properties.

Uncovering the Origin of Chirality from Plasmonic Nanoparticle/Cellulose Nanocrystal Composite Films

Sixiang Zhao et al.

Summary: This study investigates the generation of chirality and the relationship between surface-plasmon-mediated circular dichroism (SP-CD) and plasmonic-photonic couplings in co-assembled plasmonic nanoparticles and chiral photonic crystals. The characteristic SP-CD shape lines derived from the extinction dispersion of plasmonic nanoparticles in cellulose nanocrystals (CNCs) are observed in spectroscopy and simulation. It is demonstrated that the plasmonic chirality originates from a multiple scattering combination of plasmonic nanoparticles under a chiral excitation field and is determined by the coupling states.
