  1. A Porphyrin-Based Discrete Tetragonal Prismatic Cage: Host–Guest Complexation and Its Application in Tuning Liquid-Crystalline Behavior

    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.

  2. Generation of Silicone Poly-HIPEs with Controlled Pore Sizes via Reactive Emulsion Stabilization

    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.

  3. 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.

  4. Enzymatically Crosslinked Emulsion Gels Using Star-Polymer Stabilizers

    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.

  5. Synthesis of Degradable Poly[(Ethylene Glycol)-co-(Glycolic Acid)] via the Post-Polymerization Oxyfunctionalization of Poly(Ethylene Glycol)

    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.
