Mechanochromic luminescent materials have potential applications in pressure sensitive sensing due to their mechanical response properties. In this paper
a dicyanodistyrylbenzene(DCS) derivative(DCS-Bn) with aggregation-induced emission(AIE) property was synthesized
and its molecular structure was characterized by high-resolution mass spectra. 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 materials.
