Asserting its independence : A single organic molecule containing pyrene and rhodamine B chromophores separated by a peptide spacer (see structure) formed a mechanochromic material whose fluorescence could be switched from blue to bluish‐green and reddish by grinding. Modulation of the overlapped packing pattern of the pyrene excimer for blue emission was crucial for the reversible tricolored switching observed.
