- 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

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.
- Multiblock Copolymer-Based Dual Dynamic Disulfide and Supramolecular Crosslinked Self-Healing Networks
So Young An, Seung Man Noh and Jung Kwon Oh
Version of Record online: 21 FEB 2017 | DOI: 10.1002/marc.201600777
A new multiblock copolymer self-healing strategy that centers on the synthesis of block copolymers designed with different self-healing motifs incorporated into individual blocks with pendant disulfide linkages and carboxylic acids enables self-healing on macroscale damages through supramolecular metal–ligand interactions at room temperature and disulfide exchange reactions at moderate temperatures.

Version of Record online: 21 FEB 2017 | DOI: 10.1002/marc.201700001
C3h-symmetric benzotrithiophene-based hyperbranched conjugated polymer nanoparticles (BTT-HCPNs) with tunable particle sizes are prepared via Stille miniemulsion polymerization for the first time. Comparing with the corresponding star-shaped small molecule (C3h-BTT core with three diketopyrrolopyrrole arms), solution-processable BTT-HCPNs show redshifted and broader absorption spectra and narrower bandgaps, leading to higher power conversion efficiencies for solar cells based on BTT-HCPNs/PC71BM.
- Accelerated Combinatorial High Throughput Star Polymer Synthesis via a Rapid One-Pot Sequential Aqueous RAFT (rosa-RAFT) Polymerization Scheme

Version of Record online: 21 FEB 2017 | DOI: 10.1002/marc.201600780
Rapid one-pot sequential aqueous reversible addition-fragmentation transfer (RAFT): By utilizing a benchtop rapid one-pot sequential aqueous RAFT polymerization scheme, combinatorial star polymer libraries are prepared in air at microliter scale within minutes. This method opens up for new avenues for rapid bio/nanomaterial discovery.
