Summary: 10,12‐tricosadiynoic acid films were deposited on glass substrate by vacuum evaporation proceess at substrate temperatures of 273 K and 313 K, and then photopolymerized using left‐ and right‐ circularly polarized light (CPL). The resulting prepared poly(diacetylene) films changed from blue phase to red phase successfully by sample annealing at 353 K for 10 min, and the absorption spectra well reflected the red phase. Surface morphology change was not observed by anneling at 353 K. Furthermore, the CD spectra revealed that the chirality induced by CPL at 313 K was stronger that at 273 K.
