Fluorescent Vesicles Consisting of Galactose‐based Amphiphilic Copolymers with a π‐Conjugated Sequence Self‐assembled in Water

Abstract

Fluorescent vesicles considered as a mimic of natural primitive cells are prepared from poly(3-hexylthiophene)-block-poly(3-O-methacryloyl-D-galactopyranose) P3HT-b-PMAGP copolymers. The unique characteristic of such vesicular nanostructures is their architecture, which comprises a hydrophobic π-conjugated P3HT wall stabilized by a hydrophilic PMAGP interface featuring glucose units. The results of this work offer a very efficient and straightforward method for engineering well-controlled fluorescent nanoparticles (without the addition of dyes), which provide an excellent support to the study of carbohydrate-protein interactions.

Amphiphilic copolymers based on polyoxazoline and grape seed vegetable oil derivatives: self-assemblies and dynamic light scattering

“…Moreover, changing the lipophilic block architecture from a linear to a T-shape generates a branching and thus a shrinking by a factor of 2 of the nanoparticle volume, as shown by DLS on the copolymer suspensions. The presently described use of grape seed vegetable oil derivativesaslipophilic block(or natural sugar derivatives as hydrophilic block as found elsewhere), [20,24,78] sustainable renewable resources, and the demonstrated tunability of their self-assembling physico-chemicalproperties are of great interest for biomass valorization at the nanoscale level. concentration of 2 mg mL -1 in water.…”

“…Glycopolymers linked to a polystyrene block were reported to self-organize into films with inter-domain spacing of about 10 nm which underwent transition phase in presence of bipyridine. [22] Specific glycopolymers containing a silicon-based block [23] and fluorescent π-conjugated poly(3-hexylthiophene) [24] showed interesting organization behaviors in periodic films made by approximately 5 nm diameter cylinders (in dry state) and vesicles (in liquid state), respectively. The second category gathers lipopolymers based on vegetable oils or their derivatives and a hydrophilic block such as polyacrylamide, [25] poly(ethylene oxide) (PEO) or peculiar polyoxazolines such as poly(2-methyl-2-oxazoline), poly(2-ethyl-2-oxazoline) or poly(2-(2-N-pyrrolidonylethyl)-2-oxazoline).…”

Self-assembly of phosphorous containing oligomers: morphological features and pH-sensitiveness in suspension

“…This result is incompatible with the presence of hollow structures such as vesicles for which the inherent fragility in the dried state is accompanied by proles having at least one local minimum causing the structure to collapse on itself. 48 The particles have been so far physico-chemically characterized as a whole. To get more rened information about their local morphology and organization, static light scattering (SLS) is carried out on the oligomer suspensions.…”

Core–Shell Double Gyroid Structure Formed by Linear ABC Terpolymer Thin Films

“…For instance, end‐functionalized AB‐type BCP chains can be first synthesized, then different methodologies can be used to attach them to a functionalized C homopolymer. One of the most common methods to attach the different blocks deals with “click chemistry” reactions such as the azide‐alkyne Huisgen and Diels Alder cycloadditions . Even though a high yield can be achieved from click reactions, cycloadditions are generally catalyzed with metallic salt which could be a drawback for some technological applications.…”
