Properties of Enantiomers and Optical Activity

It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their applications. Just as our feet, which are chiral, interact uniquely with chiral objects, such as a pair of shoes, but identically with achiral socks, enantiomers of a molecule exhibit different properties only when they interact with other chiral media. An example of a significant implication from this facet is the phenomenon known as optical activity,...

Summary

Chiral π-conjugated polymer microspheres with textured surfaces exhibit angular-selective resonance and directional lasing. This demonstrates how surface molecular arrangement impacts optical functions in spherical resonators.

Area of Science:

  • Optics and Photonics
  • Materials Science
  • Polymer Chemistry

Background:

  • Spheres are typically isotropic, but their optical properties can be altered by non-isotropic refractive index distributions.
  • Molecular configurations within microspheres can induce birefringence, yet surface molecular arrangements' optical effects remain underexplored.

Purpose of the Study:

  • To investigate optical sphere resonators with topological and chiral surfaces.
  • To demonstrate angular-selective resonance and lasing properties arising from surface molecular arrangements.

Main Methods:

  • Self-assembly of chiral π-conjugated polymers to form microspheres with swirl molecular arrangements.
  • Characterization of whispering gallery mode (WGM) resonance and laser oscillation under photoexcitation.

Main Results:

  • Microspheres exhibited angular-selective WGM resonance emission localized along specific circular orbits.
  • Under strong photoexcitation, microspheres demonstrated WGM laser oscillation with a distinct azimuthal direction.
  • The textured spherical surface significantly impacted the optical properties.

Conclusions:

  • Surface molecular arrangement in chiral microspheres dictates optical functions, enabling angular-selective phenomena.
  • Chiral sphere resonators offer potential as spatio-selective light amplifiers and directional lasers without shape modification.
