- Switching between Polymer Architectures with Distinct Thermoresponses
Wenhui Sun, Zesheng An and Peiyi Wu
Version of Record online: 27 FEB 2017 | DOI: 10.1002/marc.201600808
Reversible switching between a well-designed linear polymer and corresponding cross-linked nanogels with distinct thermoresponses is a unique example of how the responsive properties of smart polymers can be significantly manipulated via polymer architecture engineering.
- Reactive Oxygen, Nitrogen, and Sulfur Species (RONSS)-Responsive Polymersomes for Triggered Drug Release
Zhengyu Deng, Jinming Hu and Shiyong Liu
Version of Record online: 27 FEB 2017 | DOI: 10.1002/marc.201600685
Reactive oxygen, nitrogen, and sulfur species (RONSS) are closely associated with numerous physiological functions and represent a novel category of endogenous stimuli, which can be employed as new triggering events to mediate the disassembly/cross-linking of vesicular assemblies, thereby selectively triggering the release of encapsulated therapeutic payloads in RONSS-overexpressed pathological tissues.
- Construction of Light-Harvesting Polymeric Vesicles in Aqueous Solution with Spatially Separated Donors and Acceptors

An aqueous light-harvesting antenna (LHA) is constructed by using hyperbranched polymer vesicles as scaffolds. The donors are encapsulated inside the hydrophobic core layer and the acceptors are incorporated on the shell of vesicles through host–guest interactions. Such a vesicular LHA with spatially separated donors and acceptors can avoid self-quenching effectively and shows good energy transfer efficiency of about 80% in water.
- Plants to Polyelectrolytes: Theophylline Polymers and Their Microsphere Synthesis
Ryan Guterman, Markus Antonietti and Jiayin Yuan
Version of Record online: 23 FEB 2017 | DOI: 10.1002/marc.201600748
Theophylline is a naturally occurring alkaloid extracted from chocolate and tea and is derivatized to synthesize a cationic polyelectrolyte by free-radical polymerization. Dispersion polymerization of the monomer in MeOH/EtOH mixtures allows for tuning of the microsphere sizes in an easy fashion. This work represents an ongoing effort to harness natural products for polyelectrolyte synthesis.
- Unexpectedly Facile Rh(I) Catalyzed Polymerization of Ethynylbenzaldehyde Type Monomers: Synthesis of Polyacetylenes Bearing Reactive and Easy Transformable Pendant Carbaldehyde Groups
Jan Sedláček, Lucie Havelková, Jiří Zedník, Radek Coufal, Tomáš Faukner, Hynek Balcar and Jiří Brus
Version of Record online: 23 FEB 2017 | DOI: 10.1002/marc.201600792
Rh(I) catalyzed polymerization of (ethynylarene)carbaldehydes into poly(arylacetylene)s with pendant carbaldehyde groups is reported for the first time. Surprisingly, the polymerization is not inhibited by carbaldehyde groups of the monomers. Examples of possible functional appreciation of prepared poly[(ethynylarene)carbaldehyde]s are reported, consisting in introduction of fluorescence or chirality into polymers via their postpolymerization reaction with either fluorescent of chiral primary amines.
