The recent advent of polymer mechanochemistry enables a new paradigm of design for force-responsive materials. Conjugated polymers represent a major class of functional materials with distinct optical, electronic, thermal, and chemical properties from non-conjugated polymers, and mechanochemical generation of conjugated polymers can open new avenues for mechanically responsive materials. However, this goal has several formidable design challenges. We present our design to meet all these challenges and the first example of mechanochemical generation of polyacetylene from poly(ladderene) precursors. Spectroscopic, optical, microscopic, and electronic characterizations supported the generation of polyacetylene with uniform all <i>trans</i> configurations and high conjugation length.
