Figure 3. (A) Macroscopic chiral spherulites (≈ 1 mm) formed by co-assembling LC-BCP, RhB, and chiral TA, illustrating their evolution; (B) The CPL and glum spectra of annealed films LC-BCP/L-TA/RhB and LC-BCP/D-TA/RhB were analyzed, elucidating the molecular and assembly structural alterations induced by UV irradiation and subsequent thermal re-annealing.
