Towards nanoporous membranes based on ABC triblock terpolymers.
Block copolymers represent an exciting class of complex materials as they self-assemble into highly regular structures of nanoscopic dimensions. When prepared as thin films, such structures can be used for a variety of applications including lithographic masks or nanoporous membranes. Reported here are nanostructures in thin films of structurally analogous polybutadiene-block-poly(2-vinyl pyrid...
متن کاملNucleobase-functionalized ABC triblock copolymers: self-assembly of supramolecular architectures.
RAFT polymerization afforded acrylic ABC triblock copolymers with self-complementary nucleobase-functionalized external blocks and a low-Tg soft central block. ABC triblock copolymers self-assembled into well-defined lamellar microphase-separated morphologies for potential applications as thermoplastic elastomers. Complementary hydrogen bonding within the hard phase facilitated self-assembly an...
متن کاملEffect of block sequence on the self-assembly of ABC terpolymers in selective solvent.
The effect of block sequence on the self-assembly of ABC terpolymers in selective solvent (water/THF) was explored based on two kinds of terpolymers: polystyrene-block-poly(ethylene oxide)-block-poly(acrylic acid) (PS-b-PEO-b-PAA) and PEO-b-PS-b-PAA with the same component, comparable molecular weight, but different block sequence. Copolymer PS-b-PEO-b-PAA has a higher critical water content (C...
متن کاملTriblock colloids for directed self-assembly.
Methods for functionalizing micrometer-sized colloidal spheres with three or more zones of chemical functionality (ABA or ABC) are described. To produce ABA triblock colloids, we functionalized the north pole, south pole, and equator to produce what we call X, Y, and K functionality according to the number of allowed nearest neighbors and their spatial arrangements. These synthesis methods allo...
متن کاملSelf-assembly of looped triple-stranded helicates.
The reaction of the organogold metallaligand [(AuC[triple bond]Cbpyl)(2)(mu-Ph(2)P(CH(2))(4)PPh(2))] (bpyl = 2,2'-bipyridin-5-yl) with Fe(2+) or Zn(2+) ions gave helicates where the three ligand strands adopt a unique looped geometry.
