Molecular Engineering for Chiroptical Smart Paints: Photo‐Tunable and Polymerizable Helical Nanostructures by Cyanostilbene‐Based Reactive Mesogens (Advanced Optical Materials 6/2023)

In article number 2202707, Kwang-Un Jeong and co-workers present chiroptical smart paints using cyanostilbene-based reactive mesogens. The helical nanostructures in the developed paint are precisely controlled and fixed by UV light and subsequent blue light irradiation. Corresponding chiroptical properties are investigated in detail. Furthermore, advanced optical information storages and encryptions are successfully demonstrated using the proposed chiroptical smart paints.
