Summary: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.
