Molecules with Multiple Chiral Centers

Molecules with Multiple Chiral Centers

Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2,3-diol have multiple chiral centers. A simple formula to predict the number of stereoisomers possible for a molecule with n chiral centers is 2n. However, there can be a lower number where some of the stereoisomers are...

Chirality

Chirality

Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Background:

Chiral nonlinear metasurfaces offer synergistic capabilities for wavefront manipulation and circular dichroism.
Simultaneously achieving strong chirality, precise wavefront control, and high nonlinear efficiency in metasurfaces remains a challenge.

Purpose of the Study:

To propose and demonstrate multiplexed third-harmonic (TH) holograms with four channels.
To achieve independent control over spin and chirality in nonlinear holographic imaging.

Main Methods:

Fabrication of a chiral gold-zinc oxide (Au-ZnO) hybrid metasurface.
Experimental demonstration of multiplexed TH holograms using circularly polarized light.
Characterization of TH holographic image generation and conversion efficiency.

Main Results:

Successfully demonstrated four-channel multiplexed TH holograms using the chiral Au-ZnO metasurface.
Achieved independent design of left- and right-handed circularly polarized (LCP/RCP) TH holographic images.
Measured a TH conversion efficiency of 10^-5, which is 8.6 times higher than a bare ZnO film.

Conclusions:

The developed chiral metasurface enables efficient and multifunctional nonlinear nanodevices.
This work presents a promising platform for advanced holographic applications with independent spin and chirality control.
