Organic–inorganic hybrid bent-core liquid crystals with cubic silsesquioxane cores

Abstract

Organic–inorganic hybrid bent-core liquid crystals (BCLCs) with different numbers of bent-core mesogens end-attached to inorganic POSS cores or a larger siloxane core were synthesized by hydrosilylation reactions. Their chemical structures were confirmed by NMR, IR, elemental analysis, and GPC. Antiferroelectric SmC phases are found for almost all samples. However, the layer spacing depends on the number of bent-core mesogens around the inorganic core and size of the siloxane core. Two bilayer SmCAPA phases can be observed when eight bent-core mesogens are end-attched to POSS. Monolayer SmCPA phases are obtained upon increasing the content of POSS or the size of the siloxane core.
