Influence of Linkage Chemistry on Folding, Self-Assembly, and Photoresponse of Amphiphilic Azobenzene Main Chain Polymers
Two types of amphiphilic polymers composed of azobenzene repeat units in the main chain connected either via ethynylene (acetylene) or butadiynylene (diacetylene) linkages and carrying oligo(ethylene glycol) side chains were reported. Synthesis was accomplished by polycondensation involving Sonogashira–Hagihara cross coupling and Glaser coupling, respectively. Solvent titration experiments reve...
متن کاملSynthesis and self-assembly of propeller-shaped amphiphilic molecules.
Propeller-shaped aromatic amphiphiles based on a conformationally flexible aromatic segment are shown to self-assemble into well-defined discrete nanostructures with high fluorescence characteristic.
متن کاملSynthesis and self-assembly of amphiphilic polymeric microparticles.
We report the synthesis and self-assembly of amphiphilic, nonspherical, polymeric microparticles. Wedge-shaped particles bearing segregated hydrophilic and hydrophobic sections were synthesized in a microfludic channel by polymerizing across laminar coflowing streams of hydrophilic and hydrophobic polymers using continuous flow lithography (CFL). Particle monodispersity was characterized by mea...
متن کاملHydrophilic Monodisperse Magnetic Nanoparticles Protected by an Amphiphilic Alternating Copolymer.
Iron oxide nanoparticles (NPs) with diameters of 16.1, 20.5, and 20.8 nm prepared from iron oleate precursors were coated with poly(maleic acid-alt-1-octadecene) (PMAcOD). The coating procedure exploited hydrophobic interactions of octadecene and oleic acid tails while hydrolysis of maleic anhydride moieties allowed the NP hydrophilicity. The PMAcOD nanostructure in water and the PMAcOD-coated ...
متن کاملControlled nanogel and macrogel structures from self-assembly of a stimuli-responsive amphiphilic block copolymer.
RAFT polymerization was utilized to prepare an amphiphilic block copolymer containing both hydrophilic and hydrophobic segments. The self-assembly behavior of the block copolymer into nano-scale particulate structures was studied in both water and polar organic solvents. Uniform micelle assemblies were stabilized by reaction within the hydrophobic core, which contained pendant azide groups, thr...
