NEW POLYMERIC LIQUID CRYSTALS WITH LINEAR AND NONLINEAR OPTICAL APPLICATIONS: SYNTHESIS STRUCTURAL AND DYNAMIC CHARACTERISATION USING BROADBAND SPECTROSCOPY

Objective



New liquid crystal polymers with mesogenic groups both in he main and side chains will be synthesised to produce cholesteric and chiral smetic phases. Strongly dipolar lateral substituents will be used to improve the ferroelectric, pyroelectric and optically non-linear properties. The static characterization of the phases from below the glass transition to the isotropic phase will be undertaken by DSC, polarising microscopy and X-rays. Surface effects will be studied using SEM. Molecular dynamic studies will be carried out and compared with analytical theory using broadband dielectric
spectroscopy (10-2 Hz to 9 THz). The pyro- and ferroelectric and non-linear optical properties will be investigated with a view to developing novel electro-optical applications.
