Chiral Nanostructured CuO Films with Multiple Optical Activities

Abstract

which intrinsically have stronger interaction with light are in high demand to support various biological, mechanical, electronic, optical, and imaging applications. Additionally, considering of the great power of CuO in preparing high temperature superconductors and magnetoresistance materials, and also in photoelectron chemical materials, gas sensors, lithium ion electrode materials, fieldemission emitters, and heterogeneous catalysts, [18][19][20][21] especially the reaction of epoxidation, [22] it is possible that chiral CuO materials present good catalytic performance in asymmetric epoxidation and other fields. Recently, we reported the surfactant-mediated hydrothermal synthesis of chiral CuO nanoflowers exhib-

Uncovering the Circular Polarization Potential of Chiral Photonic Cellulose Films for Photonic Applications

“…CPL can be attained either passively or actively denoted as passive CPL and CPL emission, respectively. [8,9a] The degree of CPL can be expressed using the dissymmetry factor, g . [9b,c] One strategy to enable CPL emission is by blending a chiral molecule with light‐emitting polymers .…”

Chirality at nanoscale for bioscience

“…Multilevel three-dimensional (3D) lms (ZnO, silver, CuO, NiO, and so on), with hierarchical chirality from the atomic to the micron scales, were constructed using a symmetry-breaking agent, and their cooperative assembly effect was studied. [73][74][75][76] Each lm contained three levels of chirality, which were identied with structural characterization: (1) primary distorted nanoakes/ nanoplates with atomic crystal lattices; (2) secondary helical stacking of these nanoakes to form nanoplates; and (3) tertiary micrometer-sized circinate aggregates of the chirally arranged nanoplates. Lattice defects were induced by the chiral center of the amino acid, which ultimately led to a circinate helical conguration.…”

Engineering of inorganic nanostructures with hierarchy of chiral geometries at multiple scales

“…Another interesting type of system showing how chiral hierarchically organized architectures could arise from chiral molecules by non‐classical pathway is optically active chiral supraparticles decorated with spikes or sheets 174–177 . For example, right‐handed twisting rod‐like cellulose nanocrystals (CNCs) were used as a chiral template and building block for the formation of chiral CuO/CNC composite supraparticles (Figure 15A).…”
