Frontiers of Macromolecular and Supramolecular Science symposia
Michael L. Klein and Virgil Percec introduce this Polymer Chemistry themed collection containing a selection of publications contributed by lecturers from the Frontiers of Macromolecular and Supramolecular Science symposia and friends of Christofor I. Simionescu.
Enzyme-driven biodegradable nanomotor based on tubular-shaped polymeric vesicles
Self-assembling a biodegradable nanomotor through the functionalization of tubular shaped polymersomes with catalase, showing enhanced diffusion in presence of fuel.
Highly reactive α-bromoacrylate monomers and Michael acceptors obtained by Cu(II)Br2-dibromination of acrylates and instantaneous E2 by a ligand
The importance of the order of addition of reagents in SET-LRP.
Peptide–dendron hybrids that adopt sequence-encoded β-sheet conformations
Patterning of the amino acid residues to which dendrons are grafted encodes a β-sheet structure in peptide–dendron hybrids.
ipso-Arylative polymerization as a route to π-conjugated polymers: synthesis of poly(3-hexylthiophene)
Palladium-catalyzed ipso-arylative polymerization of diphenylcarbinol-substituted thiophene derivatives proceeds to reasonably high molecular weights, but is limited by side reactions.
The secondary structures of PEG-functionalized random copolymers derived from (R)- and (S)- families of alkyne polycarbodiimides
Macromolecular micelles: a hydrophobic polyamidine backbone surrounded by hydrophilic PEG chains.
Discrete oligodimethylsiloxane–oligomethylene di- and triblock co-oligomers: synthesis, self-assembly and molecular organisation
A new class of discrete-length block co-oligomers comprising oligodimethylsiloxane (oDMS) and oligomethylene (oM) is presented.
Normal, ICAR and photomediated butadiene-ATRP with iron complexes
FeX2 or FeX3 (X = Cl ≫ Br) alone or with P ≫ X > O > N > C ligands and bromoester initiators enable the successful ATRP of butadiene in toluene at 110 °C.
Losing supramolecular orientational memory via self-organization of a misfolded secondary structure
Comparing the self-organization of two dendronized perylene bisimides reveals how structurally defective primary structure eliminates memory function via hierarchical self-organization.
Chitosan hydrogelation with a phenothiazine based aldehyde: a synthetic approach toward highly luminescent biomaterials
Hydrogelation of chitosan with a photoactive aldehyde via covalent dynamic chemistry proved an original approach towards efficient luminescent biomaterials.
Cu(0)-RDRP of methacrylates in DMSO: importance of the initiator
The controlled radical polymerization of methacrylates via Cu(0)-mediated RDRP is challenging in comparison to acrylates with most reports illustrating higher dispersities, lower monomer conversions and poorer end group fidelity relative to the acrylic analogues.
