- Thermally Stable Dibenzo[def,mno]chrysene-Based Polymer Solar Cells: Effect of Thermal Annealing on the Morphology and Photovoltaic Performances

Two Dibenzo[def,mno]chrysene-based polymers with (poly(2,2′-thiophenevinylenthiophene-4,10-[6,12-bis(2-decyltetradecyloxy)-dibenzo[def,mno]chrysene] (PTVTC)) or without (poly(4,10-bithiophene-6,12-bis(2-decyltetradecyloxy)-dibenzo[def,mno]chrysene) (PTTC)) vinylene linkage between two thiophene units are used as donor in photovoltaic cells. While the PTVTC:[6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) solar cells show a sharp decline in photovoltaic performance under thermal stress, PTTC-based devices retain 97% of the initial efficiency.
- Synthesis and Aqueous Solution Properties of Block Copolyethers with Latent Chemical Functionality

Polyglycidol-poly(allyl glycidyl ether)-polyglycidol (PG-PAGE-PG) triblock copolymers are prepared by solvent-free sequential anionic polymerization. They are considered as analogs of the Pluronic copolymers in which the chemically inert poly(ethylene oxide) and poly(propylene oxide) are substituted by PG and PAGE, which exhibit latent chemical functionality. In aqueous solution they self-associate into large particles via fundamentally different mechanism from that of their analogs.
- Radical Trap-Assisted Atom Transfer Radical Coupling of Diblock Copolymers as a Method of Forming Triblock Copolymers

A combination of consecutive atom transfer radical polymerization reactions followed by atom transfer radical coupling (ATRC)-type reactions is used to synthesize ABA triblock copolymers. The inclusion of a radical trap in the ATRC reaction phase allows for the deployment of brominated chain ends not compatible with traditional ATRC reactions, such as poly(acrylates).
- An Injectable Hydrogel with Excellent Self-Healing Property Based on Quadruple Hydrogen Bonding
Guangzhao Zhang, To Ngai, Yonghong Deng and Chaoyang Wang
Version of Record online: 25 AUG 2016 | DOI: 10.1002/macp.201600319
Injectable self-healing polymeric hydrogels are prepared by copolymerizing acrylamide with UPy-NMA. The new monomer UPy-NMA bearing quadruple hydrogen bonding is synthesized and served as physical cross-linking agent of prepared hydrogel. The fabricated hydrogel exhibits excellent self-healing and injectable property which can provide an intriguing glimpse for potential applications of tissue engineering.
- Microfluidics and Macromolecules: Top-Down Analytics and Bottom-Up Engineering of Soft Matter at Small Scales
Version of Record online: 25 AUG 2016 | DOI: 10.1002/macp.201600280
Microfluidics and polymer science is a congeniality to foster the understanding and to direct the engineering of macromolecular functional entities and materials. This article spotlights upon this synergy from two perspectives, one focusing on the analytical and one on the preparative benefit of microfluidics in polymer science and engineering, regarding both the arts of co-flow laminar and segmented-flow droplet-based microfluidics.
