چکیده

In this report, we synthesized ordered coordination polymers using polyhedral oligomeric silsesquioxanes (POSS) as a building block. A POSS with eight carboxylic terminals was coordinated with copper ions at various temperatures, forming polymeric networks. This novel coordination polymer has a long-range ordered structure.

Self-organization of a mesoscale bristle into ordered, hierarchical helical assemblies.

Mesoscale hierarchical helical structures with diverse functions are abundant in nature. Here we show how spontaneous helicity can be induced in a synthetic polymeric nanobristle assembling in an evaporating liquid. We use a simple theoretical model to characterize the geometry, stiffness, and surface properties of the pillars that favor the adhesive self-organization of bundles with pillars wo...

Hydrogen Bond Assisted Assembly of Well-Ordered Polyhedral Oligomeric Silsesquioxane Block Copolymer Composites

Blends of nanoscale fillers and polymers are of interest for a wide range of applications. Among these, block copolymer (BCP) nanocomposites are an interesting class of materials in which the block copolymer can guide the spatial location and periodic assembly of the additives. 4 This approach exploits differences between the chemical nature of the constituent blocks to direct the organization ...

The design and synthesis of an innovative octacarboxy-silsesquioxane building block.

An octacarboxy-silsesquioxane was designed and synthesised through a multiple-step regioselective reaction. This novel hybrid inorganic-organic compound presents highly attractive features for application as a building block, as it has a robust, rigid structure and a high number of carboxylic coordination sites organised in a cubic symmetry.

Simulations of Organic-tethered Silsesquioxane Nanocube Assemblies

Polyhedral oligomeric silsesquioxane (POSS) based materials are a class of organic/inorganic hybrid nanomaterials with many interesting properties. Recent experiments have demonstrated that self-assembly of tethered POSS nanocubes is a promising route to the synthesis of novel materials with highly ordered, complex nanostructures. Using a coarsegrained model developed for tethered POSS, we perf...
