Four achiral polymers with V-shaped bent-core mesogens in the main chain have been synthesized by polycondensation, and the effect of acute-angled central cores (Ar= 1,2-phenylene or 2,3-naphthylene) and lateral halogen substituents (X = F or Cl) was

Here we report the dynamics of electro-optical switching processes in the biaxial nematic phase of an oxadizole-based bent-core liquid crystal (LC). This LC exhibits optical biaxiality in the lower temperature range of the nematic phase although it e

We prepared and characterized a series of side‐chain liquid crystalline (LC) homo‐ and copolyoxetanes containing varying fractions of the mesogenic 4‐decyloxy‐4′‐cyanobiphenyl pendent and the non‐m...

An organic soluble polyimide was prepared from 3,3′-dihydroxybenzidine and 2,2-bis(phthalic anhydride)hexafluoropropane. The two hydroxy groups in the repeating unit of the polyimide thus prepared were utilized in attaching 4-nitro-4′-diphenylami

The temperature dependence of second harmonic generation efficiency have been studied to investigate the poling and relaxation dynamics of polyamic acid carrying two end-on attached chromophores of DR1 and DANS. We interpreted the experimental result

We have studied a method of pretilting liquid crystal on the surface of a substrate by photoaligning the polyimide substrate containing azo type chromophores. The liquid crystal molecules were pretilted by inducing anisotropy in the cell substrate wi

The dynamics of two main-chain nonlinear optical polymers, PA-PS and PA-MS, was studied at various temperatures below Tg. In the characterization, both the photo-induced isomerization method and second harmonic generation were employed. In the case o
