Chirality is amongst the few properties of matter that manifest themselves ubiquitously from large macroscopic objects to subatomic particles. The chiroptical properties of chiral molecules due to inherent molecular asymmetry factors are limited by the ability to synthesize large molecules. The concept of the transmission of chirality information, generally called chirality transfer or chirality induction, is an interesting approach that can be observed at different levels. The dissymmetry factors obtained using circular dichroism highlight optimized supramolecular organization between the chromophores for enhancing the chiroptical properties of the system. The inorganic or hybrid nanoobjects with morphologically controlled chirality can be used as templates to induce chirality to achiral functional molecules or nanoparticles. The chiral molecular assemblies with controllable chirality were used to synthesize chiral inorganic or hybrid nanohelices, which were then used as the template to induce chirality in achiral functional molecules, nanoparticles, or monoatomic ions.< Réduire
