The shiny diamond-like object represents the reported TPE-AQ crystal, with the crystal formation process from the TPE-AQ molecule illustrated in the top-left corner. The feather demonstrates the ultrahigh pressure sensitivity of TPE-AQ (∼60 kPa, which is a state-of-the-art performance), and the emitted colorful light represents the crystal's unique piezochromic properties.
