- A Porphyrin-Based Discrete Tetragonal Prismatic Cage: Host–Guest Complexation and Its Application in Tuning Liquid-Crystalline Behavior
Guocan Yu, Yang Ye, Zaizai Tong, Jie Yang, Zhengtao Li, Bin Hua, Li Shao and Shijun Li

Host–guest chemistry is innovatively employed to reversibly tune the liquid-crystal behavior of a smectic molecule by using a porphyrin-based 3D tetragonal prism as a host. This supramolecular approach establishes new possibilities to modulate the structures of mesophases in such materials.
- Generation of Silicone Poly-HIPEs with Controlled Pore Sizes via Reactive Emulsion Stabilization
Anaïs Giustiniani, Philippe Guégan, Manon Marchand, Christophe Poulard and Wiebke Drenckhan

Macrocellular silicone polymers are obtained by solidification of the continuous phase of a poly(dimethylsiloxane) emulsion, which contains poly(ethylene glycol) drops of sub-millimetric dimensions. Coalescence of the liquid template emulsion is prohibited by a reactive blending approach, which may serve as a model emulsification route for any type of polymeric systems.
- A Water-Based Chitosan–Maleimide Precursor for Bioconjugation: An Example of a Rapid Pathway for an In Situ Injectable Adhesive Gel

Chitosan conjugated with maleimide is proposed as a potential precursor for bioconjugation and application for in situ injectable adhesive gel. When SH–PEG–SH is applied as the crosslinker, the gel can be obtained in a few seconds without any by-products at room temperature. The gel is not only injectable but also shows biocompatibility, adhesion properties, and antimicrobial activities.
- Enzymatically Crosslinked Emulsion Gels Using Star-Polymer Stabilizers
Kai Ma and Zesheng An
Version of Record online: 27 JUL 2016 | DOI: 10.1002/marc.201600283
Emulsion gels with a wide range of compositions and tunable mechanical properties are prepared by horseradish-peroxidase-catalyzed polymerization of the phenol units on the periphery of the star emulsifiers.
- Synthesis of Degradable Poly[(Ethylene Glycol)-co-(Glycolic Acid)] via the Post-Polymerization Oxyfunctionalization of Poly(Ethylene Glycol)
Di Liu and Christopher W. Bielawski
Version of Record online: 27 JUL 2016 | DOI: 10.1002/marc.201600336
To enhance the limited degradability of poly(ethylene glycol) (PEG), a straightforward method of synthesizing poly[(ethylene glycol)-co-(glycolic acid)] is described. Hydrolytically labile ester groups are directly incorporated into the polymer backbone via a ruthenium catalyzed C–H oxyfunctionalization reaction with minimal molecular-weight reduction under some conditions. The method should facilitate access to a variety of degradable PEG platforms.
