Helical Nanoplatelet Superlattices Assembled from Green Emissive CsPbI3 Nanoplatelets
Abstract
We report the synthesis and self-assembly of green emissive CsPbI3 nanoplatelets with thickness of two monolayer (2 ML). This nanoplatelet assemblies show three-dimensional stacking pattern and chiral optical response without chiral ligands/templates. Addition of extra chiral molecules or carbon dots enables 100% control over circular dichroism signals.
