Polar Order

In this paper we consider the behavior of a number of side chain liquid crystal polymers having the same mesogenic group and relate their liquid crystalline behavior to their polarization and nonlinear optical properties. We show that the liquid crystallinity of the materials results in an enhancement of the polar order over that of isotropic materials, in qualitative agreement with molecular statistical models.

Crystal Polymer

The synthesis of polyacetylene-bearing pyrimidine-type three-ringed mesogenic core exhibiting smectic C (SmC) characteristics was conducted. Gas-phase iodine doping of the polymer provided evidence of chemical interaction between the polyene and iodine, which acted as an electron acceptor. The side-chain fluorine atom tilted the mesogen moiety to form SmC as a tilted liquid crystal. The addition of a small amount of chiral inducer yielded SmC* of the polymer as the chiral version of SmC. The liquid crystallinity and electronic properties of the π-conjugated chiral liquid crystal polymer with a helical structure were evaluated.
