AB Piezochromic materials, which show color changes resulting from external pressure ormechanical grinding, are of great interest from a scientific viewpoint owing to theirpotential applications as pressure-sensing and optical-recording systems.[1] It hasbeen recently discovered solid-state fluorescence properties and piezochromicluminescence in a family of 9,10-Bis((E)-n-(pyrid-2-yl)vinyl)anthracene, BPnVA (n=2orto-,3 metha- and 4 para-) compounds, see Figure 1.[2] The crystal structures indicatethat the three compounds with varying position of the nitrogen on the external pyridylexhibit different molecular packing modes. In this work, we aim at providing furtherinsight into the interplay played by the molecular and supramolecular structuralchanges and the luminescence changes observed under pressure by using a combinedexperimental-theoretical approach that links Raman spectroscopy with DFTcalculations.
