β¦ Synopsis
Synthetic routes towards monodisperse polyhedral liquid-crystalline silsesquioxanes are described. The liquid-crystalline phase behaviour of these structurally uniform materials, with various silsesquioxane core and mesogenic side-chain structures, were analysed and compared with those of related oligomeric and polymeric materials. Common features of the solid-state behaviour of these organic/inorganic hybrids, which form self-organized structures in their soft-matter states, were identified. Copyright

## Abstract Polyhedral oligomeric silsesquioxane (POSS) cages containing an iminofullerene species are reported herein. Monosubstituted benzyl chloride POSS was synthesized, and subsequently reacted with sodium azide to form mono benzyl azide POSS. The azide was subsequently reacted with C~60~ in a
A diverse and entirely new class of monomer and polymer technology based on polyhedral oligomeric silsesquioxane (POSS) reagents has been developed. POSS reagents are unique in that they are physically large (approx. 15 A Λdiameter and 1000 amu) and are composed of a robust silicon-oxygen framework
## Abstract The aggregation of polyhedral oligomeric silsesquioxane (POSS) in copolymers was studied by incorporation of POSS into fluorinated copolymers, namely poly(octafluoropentyl acrylate) elastomers. The aggregation of POSS in copolymers affords unique materials. Studies of these novel polyme
## Abstract **Summary:** Octamaleimidophenyl polyhedral oligomeric silsesquioxane (OmipPOSS) was synthesized via the imidization reaction between octaaminophenyl polyhedral oligomeric silsesquioxane (OapPOSS) and maleic anhydride, and it was characterized by means of Fourier transform infrared (FTI
