The formation of switchable and metastable discrete structures through chiral self-sorting
A paper titled "Thermo-/Mechano-Chromic Chiral Coordination Dimer: Formation of Switchable and Metastable Discrete Structure through Chiral Self-Sorting" describes chiral coordination dimers that emerge based on effectively exclusive chiral self-sorting. The complex also exhibits thermo-/mechano-chromism originating from monomer-dimer transformation. The paper is published in the Journal of the American Chemical…
