Specular X-ray reflectivity measurements are used to examine photoinduced surface roughness of side-chain coumarin polymers that form liquid crystal photoalignment layers. Thin films were irradiated with polarised or unpolarised ultraviolet light and

After nearly 20 years of intense research, ferroelectric liquid crystals are now being used in commercial devices. This timely review will consider the structural units and their specific combinations that can be used to generate the required smectic

Ultra-fast optical intensity modulators are required for high speed telecommunications and organic electro-optical materials offer the advantages of low cost and fast switching capability. We propose a new method to fabricate electro-optical waveguid

A surface anisotropy has been shown previously to be induced in thin films of photoreactive coumarin side-chain polymers by polarized UV illumination. Consequently, the resultant cross-linked polymer layers can be used as photoalignment layers for li

A range of ortho-dichloroterphenyls has been prepared and evaluated for their transition temperatures and physical properties. The analogous ortho difluoro-substituted materials have been very successful as ferroelectric host materials. It was expect

In this paper, a range of polymethacrylate derivatives of hydroxycoumarin are investigated as photoinduced alignment layers for liquid crystals, and their performance is compared with polyvinyl cinnamate. For al the coumarin- containing polymers, the

Lateral substitution in the peripheral phenyl groups of the triphenylen-2,3,6,7,10,11-hexayl hexakis(4-alkoxybenzoate)s was investigated via substitution of methyl, ethyl, isopropyl and tert-butyl groups ortho to either the peripheral alkoxy chain or
