- TITLE
- [GS_C_MS] Chirality knob: from molecules to hybrid organic-inorganic metal halides
- ABSTRACT
- Chirality is an important structural property: right-handed and left-handed chiral materials have identical chemical composition and connectivity, but they are related by mirror transformation, forming a couple of enantiomers. Chiral materials show unique features: the intrinsic non-centrosymmetry leads to optical rotation, circular dichroism (CD), second-harmonic generation (SHG), piezoelectricity, pyroelectricity, ferroelectricity, and topological quantum properties. In this talk, I will discuss the intriguing interplay between chirality and physical properties in innovative materials, ranging from molecules, twisted bilayers (non-magnetic as well magnetic) to chiral hybrid organic-inorganic perovskites. We will see that it is possible to “generate” and “tune” chirality in such a way that it can be view as a new “knob” for physical properties of the materials.
