Analysis by the Two-Fluids Model of the Dynamical Behavior of a Viscoelastic Fluid Probed by Dynamic Light Scattering

, 2004
The dynamic properties of a model transient network have been studied by dynamic light scattering. The network is formed by microemulsion droplets linked by telechelic polymers (modified hydrophilic polymers with two grafted hydrophobic stickers).

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Hydrogelation via Supramolecular Copolymerization of Structural Water within Adaptive Metal–Organic Fibers

Advanced Materials, EarlyView.
Structural water is harnessed as an active co‐monomer to drive supramolecular polymerization in bulk water. Zinc(II) Salphen complexes confine water molecules to form hollow, metal–organic nanofibers that assemble into adaptive hydrogels with thermoresponsive mechanics and selective chiral recognition.

Guest‐Induced Activation of Multicolor Photoluminescence in Naphthalene Bisimide Liquid Crystals

Advanced Materials, EarlyView.
Supramolecular host–guest design in naphthalene bisimide liquid crystals activates charge‐transfer emission and enables continuous tuning of color (511–685 nm) and lifetime, spanning prompt fluorescence, TADF, and RTP. Electron‐rich guests and Pt(II) complexes modulate emissive states, while co‐assembled NBI complexes create an energy‐transfer cascade ...
