Silver Nanoarrays Templated by Block Copolymers of Carbosilane Dendrimers and Polyisocyanopeptides

Self‐Assembled Nanoreactors

“…Micellar fibers of (Figure 26). 237 The polymer micelle-metal hybrid itself can also be considered to be a nanoreactor, because the catalytically active metal colloid is buried inside the micelle core and the reactants have to pass the micellar shell to reach the interior. These hybrid particles combine the advantages of homogeneous and heterogeneous catalysis, because they can be dissolved in organic solvents, due to their polymeric shell, while catalyst recovery is straightforward by performing ultrafiltration or precipitation in poor solvents for the polymer.…”

Hollow Inorganic Nanospheres and Nanotubes with Tunable Wall Thicknesses by Atomic Layer Deposition on Self‐Assembled Polymeric Templates

“…[23,24] Complementary physical interactions, which are dealt with in supramolecular chemistry, [25] can be applied to bind further structural moieties within block copolymers to achieve additional hierarchy levels, [26] prepare discrete nanoscale objects, [24,27] or direct the self-assembly of inorganic materials. [28][29][30][31][32] In particular, hydrogen-bonded polymer-surfactant complexes of polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) and alkyl phenols, such as pentadecyl phenol (PDP) and dodecyl phenol (DDP), lead to discrete PS-b-P4VP nanorods with a PS core and P4VP corona. [27,33,34] The advantages of such a supramolecular approach include: i) reduction of the glass-transition temperature (T g ) of both phases (T g (PS) ≈ 67°C; T g (P4VP/PDP) ≈ room temperature) [35] to allow shear alignment at moderate temperatures for improvement of the self-assembled structures; and ii) preparation of PS-core-P4VP-corona nano-objects by simple dissolution of PDP.…”

Transport and Electro‐Optical Properties in Polymeric Self‐Assembled Systems

“…Diblock copolymers consisting of dendritic bulky and flexible [352,353]. nonpolar carbosilane block and rigid helical polyisocyanide blocks form complexes with silver ions and lead to nanowires [365]. Distinct nanowires can be achieved by using polystyrene-b-poly(4-vinylpyridine) where pentadecylphenol is hydrogen bonded to the pyridines, which leads to hierarchical self-assembly [366]: Polystyrene cylinders within poly(4-vinylpyridine)-pentadecylphenol can be obtained and, after aligning and removing the pentadecylphenol, distinct polystyrene wires with a poly(4-vinylpyridine) corona are obtained [86,109,367], which can be metallized with CdSe, Pd, Ag and Au [368,369].…”
