Second ligands-assisted structural variation of entangled coordination polymers with polycatenated or polythreaded features
The self-assembly of transition metal salts with dicarboxylate ligands and second ligands afford a series of entangled coordination frameworks based on different metal clusters, namely, [Ni2(oba)2(bpy)2(H2O)2]·(DMF)(H2O)2 (1), [Ni2(oba)2(bpy)2(sa)(H2O)2]·(H2O)4 (2), [Cu5(oba)4(bpy)5(pca)2(H2O)4]·(H2O)9 (3), [Co3(oba)2(bpy)2(dbca)2]·(H2O)6 (4), [Co3(oba)2(dbca)2(H2O)] (5...

Molecular Origin of the Shape Memory Properties of Heat-shrink Crosslinked Polymers as Revealed by Solid-state NMR
Understanding the shape memory properties of heat-shrink polymers (HSPs)
at the molecular level is crucial for the design and synthesis of advanced HSP
materials. Herein, we employed a
variety of in situ variable-temperature (VT) solid-state nuclear magnetic
resonance (NMR) techniques, in combination with other methods, to investigate
the evolution of the individual components of a poly(ethyl...

[Chem. Commun.] A new avenue to the synthesis of GAG-mimicking polymers highly promoting neural differentiation of embryonic stem cells
A new strategy for the fabrication of glycosaminoglycan (GAG) analogs was proposed by copolymerizing the sulfonated unit and the glyco unit, ‘splitted’ from the sulfated saccharide building blocks of GAGs. The synthetic polymers can promote cell proliferation and neural differentiation of embryonic stem cells with the effects even better than those of heparin.

[J. Mater. Chem. ] Facile preparation of cancer-specific polyelectrolyte nanogels from natural and synthetic sugar polymers
Glyco-nanogels are glycopolymer-decorated nanoparticles of three-dimensional cross-linked networks, which have attracted ever-increasing interest of the biomedical-related community. However, most of the current reported glycosylated nanogels are prepared by copolymerization of glycopolymers with co-monomers and cross-linkers. Physically self-assembled glyco-nanogels remain a big challenge and a...

[Polym. Chem.] Fe(0) powder-catalyzed one-pot reaction: concurrent living radical polymerization and click chemistry for topological polymers
Fe(0) powder-catalyzed one-pot reaction was successfully employed to design linear and star polymers in a well-controlled manner by combining ambient temperature living radical polymerization and click chemistry. The polymerization behavior possessed the characteristics of “living”/controlled radical polymerization: the first-order kinetic plots, narrow molecular weight distribution (PDI < ...

Flame Retardant Electrical Conductive Nano-polymers based on Bisphenol F Epoxy Resin Reinforced with Nano Polyanilines
Both fibril and spherical polyaniline (PANI) nanostructures have successfully served as nanofillers for obtaining epoxy resin polymer nanocomposites (PNCs). The effects of nanofiller morphology and loading level on the mechanical properties, rheological behaviors, thermal stability, flame retardancy, electrical conductivity, and dielectric properties were ...

(Polym. Chem.) An Entropy-Driven Ring-Opening Metathesis Polymerization Approach towards Main-Chain Liquid Crystalline Polymers
The known synthetic methods of preparing main-chain liquid crystalline polymers (MCLCPs) are rather limited to several polycondensation reactions. However, the nature of step-growth polycondensation endows the corresponding MCLCPs with relatively low molecular weights and broad molecular weight distributions. In this manuscript, an entropy-driven ring-opening metathesis polymerization (ED-ROMP) ...
