Photochromic spiropyran-based liquid crystals
Original language description
We present a new type of light responsive self-assembling structures based on a spiropyran photoswitchable unit. The spiropyran central part was modified by functional groups, which enabled the connection of two structurally different elongating parts. Two series of compounds were prepared with reversed orientation of the ester as a linkage group in the molecular core. The properties of the target materials were studied by differential scanning calorimetry and polarizied light optical microscopy, which proved the presence of a nematic phase for most of the materials. In case of a trifluromethyl-substituted compound, a sequence of nematic - smectic A - smectic C phase was detected and confirmed by X-ray diffraction analysis.
