A new type of bis‐polydiacetylene (PDA), in which two PDAs are linked via an intervening p‐phenylene group, displays excellent thermochromic reversibility. Clear blue‐to‐red and red‐to‐blue colorimetric transitions are observed by R. Chang, J. Yoon, and co‐workers between 20 and 120 °C. The first theoretical simulation of the new PDA is reported on page 3699, the results of which successfully explain the thermochromic reversibility phenomenon.
