Highlight from Jyväskylä - Xiamen collaboration

This collaborative work between Nanoscience Center (Acad. prof. Häkkinen) and Xiamen University (prof. Nanfeng Zheng) demonstrates a new method to synthesize and characterize optically pure ultra-small chiral Au-Cu clusters protected by pyridinethiols and chiral diphosphines. DFT calculations done at the NSC reveal the details of the origin of the chiral optical response of these nanomaterials, which resist racemization up to 70 C making them potentially interesting materials for enantioselective catalysis.

The research "From symmetry breaking to unraveling the origin of the chirality of ligated Au13Cu2 nanoclusters" was published in Angewandte Chemie 2018.
