Organic luminescence with different forms continues to be one of the most active research fields in science and technology. Herein, an ultra‐simple organic molecule (TPA‐B), which exhibits both mechanoluminescence (ML) and photo‐induced room‐temperature phosphorescence (RTP) in the crystalline state, provides an opportunity to reveal the internal mechanism of ML and the dynamic process of photo‐induced RTP in the same molecule. Through the detailed investigation of photophysical properties together with crystal structures, the key role of molecular packing and intermolecular interactions was highlighted in the luminescence response by mechanical and light stimulus, affording efficient strategies to design potential smart functional materials with multiple luminescence properties.
