Chirality refers to a geometrical property when an object cannot be superimposed onto its mirror image. In addition to its important role in biochemical and chemical processes, chirality leads to different interactions of molecules and structures with right- and left-handed circularly polarized light. Recently, chiral colloidal nanoparticles and nanostructures [1] have been of great interest, demonstrating different absorption of right- and left-handed circularly polarized light (circular dichroism, CD) or rotation of the light polarization plane (optical activity), as well as the emission of photons of a given circular polarization (circularly polarized luminescence). In this repot, we present an analysis of 2D atomically thin nanostructures of cadmium and zinc chalcogenides hybridized with stereoisomeric L-/D-ligands and showed a distinctive CD in excitonic transitions.
