Aiming at the further extension of the application scope of traditional molecular muscles, a novel bispyrene-functionalized chiral molecular c2daisy chain was designed and synthesized. Taking advantage of the unique dimeric interlocked structure of molecular c2daisy chain, the resultant chiral molecular muscle emits strong circularly polarized luminescence (CPL) attributed to the pyrene excimer with a high dissymmetry factor (g
