Preparation of metallosupramolecular single-chain polymeric nanoparticles and their characterization by Taylor dispersion

Abstract

Polymers with pendant ligands furnish single-chain polymeric nanoparticles upon intramolecular metal–ligand complex formation with different metal-ions and Taylor dispersion analysis is employed to reliably characterize the dispersed particles.

Heterobimetallic Au(i)/Y(iii) single chain nanoparticles as recyclable homogenous catalysts

“…Moreover, we were challenged to use a rare earth element to induce the chain collapse to broaden the method of metal induced SCNP formation significantly. 29 Rare earth ions sig-nificantly differ in their synthetic chemistry from main group and transition metals by their higher coordination numbers, which are a result of their larger ion radii. While most transition metal complexes have coordination numbers of 4-6, coordination numbers of 7-9 or even higher are frequently seen for rare earth metals.…”

Cyan-Emitting Cu(I) Complexes and Their Luminescent Metallopolymers

“…Indeed, the covalent attachment of metal–organic complexes to polymer chains has been shown to prevent phase separation and to enhance the properties of the functional groups (e.g., in catalysis). At the same time, unique properties such as unimolecular micellization have also been reported [ 23 , 24 , 25 ]. Furthermore, such hybrids improve processability and give the metal complex increased stability [ 26 ].…”

Endosomal pH-Responsive Fe-Based Hyaluronate Nanoparticles for Doxorubicin Delivery

“…In particular, metal-containing biopolymer nanocomposites have been actively designed for engineering multifunctional drug carriers with specific biological functions and tunable hyperstructures [1][2][3]. For example, the complexation of Fe and biopolymers is an effective and simple approach to fabricate biocompatible nanosized drug carriers in that Fe is an element present in living organisms and can be used as a chelating agent for negatively charged biopolymers [4][5][6][7]. Moreover, Fe-based nanocomposites are easy to control in terms of their composition, shape, size, and surface characteristics as a result of different mixing ratios and biopolymer types [4][5][6][7].…”

It is also interesting to note that the combination of biopolymers reactive to specific stimuli (light, temperature, pH, etc.)…”
