Lighting up solid states using a rubber

Abstract: It is crucial and desirable to develop green and high-efficient strategies to regulate solid-state structures and their related material properties. However, relative to solution, it is more difficult to break and generate chemical bonds in solid states. In this work, a rubbing-induced photoluminescence on the solid states of ortho-pyridinil phenol family was achieved. This rubbing response relied on an accurately designed topochemical tautomerism, where a negative charge, exactly provided by the triboelectric… Show more

“…[ 14 ] The generated hydrogen bonds led to the decrease in the bandgap of DPP and the redshift of the emission. [ 10 ] Furthermore, the peaks at 2917 and 2846 cm −1 remain the same, which means that the packing mode of alkyl chains are unchanged.…”

“…Undoubtedly, molecular motions, especially in the solid state, are responsible for macroscopic mechanical movements. 31,32 The photophysical properties of organic materials essentially depend on the molecular motions at the molecular levels. The emission color switching favors visual optical readouts and is readily monitored spectrophotometrically.…”
