AngewChem--Design of Aromatic Helical Polymers for STM Visualization: Imaging of Single and Double Helices with a Pattern of pi–pi Stacking
From scanning tunneling microscopy (STM) images of rationally designed helical polymers with a pattern of pi–pi stacking, we successfully identified the single- and double-helical superstructures. The STM images of the helical structures revealed the smallest helical architecture (diameter ca. 1.3 nm) that has been seen so far. Furthermore, the interconversion of single and double helices was fur...

Supramolecular self-assembly of amphiphilic hyperbranched polymers at all scales and dimensions: progress, characteristics and perspectives
This feature article describes the supramolecular self-assembly of hyperbranched polymers
(HBPs), including the progress, unique characteristics and future
perspectives. HBPs are irregular in molecular structure compared with
that of linear block copolymers and dendrimers. However, similar to these well-defined polymer tectons, HBPs have displayed great potential to be excellent precursor...

Honeycomb-Structured Microporous Films Made from Hyperbranched Polymers by the Breath Figure Method
Honeycomb-structured microporous films were self-assembled from a new
type of multiarm copolymer, hyperbranched
poly(3-ethyl-3-oxetanemethanol)-star-polystyrene (HBPO-star-PS).
The precursor consisting of an HBPO core and a number of PS arms was
synthesized by reversible addition fragmentation chain transfer (RAFT)
polymerization. The microporous film was prepared by the evaporation of...

[Polym. Chem.] Morphology transitions of supramolecular hyperbranched polymers induced by double supramolecular driving forces
Tuning the morphology of supramolecular hyperbranched polymers (SHPs) in solution has theoretical and practical significance in SHP applications. This study successfully achieved SHP morphology transitions from branched supramolecular structures to spherical nanosized micelles in mixed solvents. Transmission electron microscopy, dynamic light scattering, 2D 1H NMR ROESY, and fluor...

[Reactive and Functional Polymers] Optical bandgaps and fluorescence resonance energy transfer studies of a series of poly(phenyleneethynylene) derivatives
In this paper, research work focuses on the synthesis of a series of PPE-based polymers with commonly used conjugated units, including thiophene, benzo[c][1,2,5]thiadiazole (BT), benzo[c][1,2,5]selenadiazole (BSe), etc. The optical bandgaps of these polymers were tuned in the range of 2.10–2.76 eV. The order of bandgap-lowering ability of these units in PPE-derivatives is: M-3 >&nb...

Effect of internal phase contents on porous polymers prepared by a high internal phase emulsion methods.
A series of porous polymers
poly(styrene-divinylbenzene) was synthesized by the polymerization of 9 : 1 (v/v)
styrene/divinylbenzene using high-internal-phase emulsions (HIPEs) as template,
cetyltrimethyl ammonium bromide as a surfactant in the presence of
water-miscible organic additives ethanol, with internal-phase contents varied
from 82.5 to 94.0%. The effects of the internal-phase contents ...

MacromolRapidCommun--Selenium/Tellurium-Containing Hyperbranched Polymers: Effect of Molecular Weight and Degree of Branching on Glutathione Peroxidase-Like Activity
A series of novel hyperbranched polyselenides and polytellurides with multiple catalytic sites at the branching units has been synthesized via the polycondensation of A2 + B3 monomers. The GPx-like activities of these polymer mimics were assessed and it was found that the polytellurides showed higher GPx-like activities than the corresponding polyselenides. Interestingly, the polymers with higher ...

Self-Assembly of Polyoxometalate-Based Starlike Polymers in Solvents of Variable Quality: From Free-Standing Sheet to Vesicle
Polyoxometalate-based supramolecular
star polymers, where an anionic polyoxometalate is closely encapsulated by a hydrophobic shell of cation
terminated polystyrenes, are conceptually regarded as a model of star polymers to study their intra- and
inter-star interactions and self-assembled behaviors in solvents of
variable quality. These model stars can self-assemble to form
unilamellar free-stan...

[Polym Chem] Novel phthalocyanine and PEG-methacrylates based temperature-responsive polymers for targeted photodynamic therapy
A novel multi-targeting nanocarrier (SiPc-polymer) for photodynamic therapy (PDT) has been successfully polymerized via the incorporation of silicon(IV) phthalocyanine dichloride (SiPcCl2) to the thermoresponsive PEG-methacrylates based polymers. The resulting SiPc-polymer was characterized by1H NMR spectroscopy, GPC, UV-Vis and elemental analysis. The lower critical solution temperature (LCST) ...
