Two pyrene boronic acid cyclic esters, PPB and NPB, were prepared and their solid state fluorescence properties were investigated. Interestingly, the results showed that PPB with a 5-membered ring possessed reversible mechanoluminescence and vapochromic behaviour with a fast self-recovering ability at room temperature, whereas NPB with a 6-membered ring did not. It was demonstrated that the mechanically responsive fluorescence properties of PPB and NPB were highly related to the molecular packing mode and the solid state plasticity.
