Piezofluorochromism of an Aggregation‐Induced Emission Compound Derived from Tetraphenylethylene

Easy piezy: A new piezofluorochromic-aggregation-induced emission compound is described. The spectroscopic properties and morphological structures were reversibly exhibited upon pressing and annealing. The piezofluorochromic nature is believed to be generated through phase transformation. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
