Abstract

Mechanofluorochromic (MFC) materials, as a kind of fluorescence stimulus response materials, can show obvious changes under external stimuli, so it has become a research hotspot in the field of advanced optical materials. MFC compounds can further benefit their properties from stimulus-responsive materials with aggregation-induced emission (AIE) characteristics. Therefore, by combining triphenylethylene with benzimidazole derivatives, we designed and synthesized a simple organic small molecule DTITA with AIE and reversible mechanofluorochromism characteristics, and the material of solid fluorescence can be regulated through the utilization of mechanical grinding and DCM fumigation cycles. This offers a new way for the invention of new intelligent materials.
