Molecular insertion regulates the donor-acceptor interactions in cocrystals for the design of piezochromic luminescent materials

Abstract

The design of piezochromic luminescent materials with desirable stimuliresponsive properties remains challenging. Here, the authors report the insertion of a non-emissive molecule into a donor and acceptor binary cocrystal and realize desirable piezochromic luminescent properties by manipulation of intermolecular interactions between the donor and acceptor molecules.
