Unravelling Competitive Interactions between Polymer Side Chains and End Groups with β-Cyclodextrin

This study investigates unexpected competitive host-guest interactions of β-cyclodextrin (β-CD), which can occur with polymers in aqueous solution, using the examples of the two polymers poly(oligo(ethylene glycol) methyl ether methacrylate) and poly(glycerol mono methacrylate). Systematic structural modifications of the polymer provide insight into the host-guest interaction with β-CD and the competition between side chains and end groups such as hydrophobic end groups remaining from reversible addition fragmentation chain transfer polymerization or intentionally implemented molecular recognition units such as arylazopyrazole photoswitches.

Synthesis and self-assembly of a dual thermal and pH-responsive ternary graft copolymer for sustained release drug delivery

Schematic illustrations of the self-assembly of TGCs and possible loading and release mechanism.

Synthesis of hybrid silica nanoparticles grafted with thermoresponsive poly(ethylene glycol) methyl ether methacrylate via AGET-ATRP

This emulsification–demulsification inversion related to the temperature-responsive surface chemistry could in future be exploited for separation and recycling of catalysts.

A pH-responsive amphiphilic supramolecular graft copolymer constructed by crown ether based molecular recognition

Based on the bis(m-phenylene)-32-crown-10/paraquat molecular recognition motif in water, we have successfully prepared an amphiphilic supramolecular graft copolymer by the combination of modified hydrophilic poly(ethylene oxide) and hydrophobic polystyrene. It could self-assemble into pH-responsive bilayer vesicles in water.

High thermo-responsive shape memory epoxies based on substituted biphenyl mesogenic with good water resistance

In this work, a novel epoxy monomer denoted as 3,5′-di-t-butyl-5,3′-dimethyl biphenyl diglycidyl ether was synthesized and applied intoin situcomposites with 3,3′,5,5′-tetramethyl-4,4′-biphenyl diglycidyl ether, accompanied with curing agent aromatic amines.

Novel lanthanide–polymer complexes for dye-free dual modal probes for MRI and fluorescence imaging

High-resolution imaging is a powerful technique in theranostics and staging of tumors.

Synthesis and encapsulation of an amphiphilic thermoresponsive star polymer with β-cyclodextrin and hyperbranched poly(oligo(ethylene glycol)methacrylate) as building blocks
