Abstract : Molecular tailoring concepts were applied to the synthesis of novel inorganic and organometallic polymers, many of them starting from commonly available polymorphs of SiO2 (beach sand). Liquid crystalline molecular order was identified in random co-oligomers and copolymers of bis(catecholato) spirosiloxanes. Factors affecting the nature and distribution of microstructural defects in liquid crystalline materials were identified, with a view to minimizing the scattering of light as it passes through such materials....
