Naphthyl imide compound with aggregation-induced emission enhancement, solvent discoloring and self-resilience photochromic properties and application

The invention relates to a naphthyl imide compound with aggregation-induced emission enhancement, solvent discoloring and self-resilience photochromic properties and an application. The naphthyl imidecompound has a structure shown as formula I. The compound can weakly illuminate in a solution; strong green fluorescence is shown and an obvious aggregation-induced emission enhancement property is shown once the compound is aggregated; meanwhile, the compound also can show different fluorescence colors in the solvents with different polarities, so that the solvent discoloring property is shown;and besides, the color of the fluorescent light can become green from blue green after the solid sample of the compound is mechanically polished and the fluorescence can automatically restore to the corresponding blue green fluorescence after the polished solid sample is stored under room temperature, so that the self-resilience photochromic property is shown. Thus, the compound is expected to beapplied to the fields of lu
