Experimental evidence for Sm-CG-->Sm-CP polymorphism in fluorinated bent-shaped mesogens.
We report the experimental results on pure fluorinated bent-shaped mesogens showing very unusual textures and electro-optical behavior. In the view of recent publications such behavior can be explained by triclinic symmetry of the mesophase (Sm-C(G)) formed by these compounds. Based on the results of the x-ray diffraction and electro-optical investigations, we give evidence for the Sm-C(G) -->Sm-CP polymorphism.
