A new tetraphenylethylene (TPE) functionalized 1,4-dihydropyrrolo[3,2-<i>b</i>]pyrrole derivative (<b>APPTPECN</b>) was synthesized with obvious aggregation-induced emission (AIE) active by simple synthetic method. <b>APPTPECN</b> exhibited reversible mechanofluorochromic (MFC) behavior. The powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM) investigations exhibited that the MFC nature is originated through a conversion from the microcrystalline to amorphous phase under the stimulus of external force. The results obtained would be of major help in understanding the MFC mechanism and designing new MFC materials. Compound <b>APPTPECN</b> has the potential possibility to employ in rewritable data storage and is of assistance in the rational design of smart luminescent materials.
