Growing of local smectic C monocrystals from an initially twisted nematic phase

The growing of smectic C single local monocrystals was investigated from an initially twisted nematic phase with smectic C ordering (p‐n‐alkoxybenzoic acid). Characteristic longitudinal and transverse dislocation lines have been observed at growth in a thin liquid crystal cell, single local monocrystals are discussed. The evolution was studied of the smectic C phase from cybotactic groups in a nematic phase toward needlike nuclei near to the nematic‐smectic C phase transition and after that after that toward the local single monocrystals.
