The photophysical properties of DCS-Bn were studied by absorption spectra and fluorescence emission spectra. Furthermore, the aggregation structures of DCS-Bn were measured by differential scanning calorimetry and X-ray diffraction experiment. The results revealed that DCS-Bn has high efficiency luminescence both in solution and solid state. DCS-Bn has the mechanofluorochromic property due to its unique rod molecular structure and the changes of aggregated structures(crystalline or amorphous state). The fluorescence emission color can recover to pristine state through solvent fuming or heating treatment, thus, DCS-Bn has potential application value in the fields of rewritable fluorescent
