CO2-Responsive fluorescent hyperbranched poly(ether amine)s

Hyperbranched polymers bearing a fluorophore display gas-controlled fluorescence switching as a result of reversible protonation/deprotonation of amino groups in their structure.

Nanoporous ionic organic networks: stabilizing and supporting gold nanoparticles for catalysis

Nanoporous ionic organic networks (PIONs) with a high ionic density (three cation-anion pairs per unit) have been synthesized by a facile SN2 nucleophilic substitution reaction. Owing to the electrostatic and steric effect, those ionic networks with porous channels can stabilize and support gold (Au) nanoparticles (NPs) in 1-2 nm. The Au@PION hybrid materials used as a heterogeneous catalyst were highly active, selective, and stable in the aerobic oxidation of saturated alcohols.

Dendritic nanocarriers based on hyperbranched polymers

The use of hyperbranched polymers as an alternative to perfect dendrimers as nanocarrier systems for drugs, dyes and other guest molecules is covered. Different types of hyperbranched polymers are discussed with regard to aspects like synthesis, functionalisation and encapsulation properties but also their degradation.

A facile synthesis of branched graft copolymers via combination of RAFT self-condensing vinyl polymerization and aldehyde–aminooxy reaction

A facile synthetic route to the branched graft copolymer BPDEM-g-PEO has been developed by combination of the RAFT-SCVP technique and aldehyde–aminooxy reaction.
