Ionic-Liquid-Grafted Rigid Poly(p-Phenylene) Microspheres Efficient Heterogeneous Media for Metal Scavenging and Catalysis
Novel guanidinium ionic liquid-grafted rigid poly(p-phenylene) (PPPIL) microspheres have been developed for metal scavenging and catalysis. The noble-metal nanoparticles supported on the microspheres surface can be used as efficient heterogeneous catalysts. The combination of nanoparticles and ionic liquid fragments on the microsphere surfaces enhance the activity and...

Oxygen electroreduction promoted by quasi oxygen vacancies in metal oxide nanoparticles prepared by photoinduced chlorine doping
Quasi oxygen-deficient indium tin oxide nanoparticles (ITO NPs) were prepared by photoinduced chlorine doping, and exhibited much enhanced electrocatalytic activity for oxygen reduction reaction (ORR) in alkaline media, as compared with pristine ITO.

Regio-selective synthesis of polyepichlorohydrin diol using Zn–Co(III) double metal cyanide complex
A simple one-pot ring-opening polymerization (ROP) of epichlorohydrin (ECH) was successfully performed by a heterogeneous Zn–Co(III) double metal cyanide complex (Zn–Co(III) DMCC) catalyst, affording regioregular poly(ECH) diol with a head-to-tail content of >99% in the absence of organic solvent and/or protic compound. No cyclic or oligomer by-product was observed, and the e...

Alternating copolymerization of carbonyl sulfide and Cyclohexene Oxide catalyzed by zinc–cobalt double metal cyanide complex
This paper describes the first example of alternating copolymerization of carbonyl sulfide (COS) with cyclohexene oxide (CHO) via heterogenous catalysis of a nano-lamellar zincecobalt(III) double metal cyanide complex (ZneCo(III) DMCC), providing an efficient method for converting COS to poly(cyclohexene monothiocarbonate) (PCHMTC) with an alternating degree up to 93%. The number-avera...

Hydrophilic PVA-co-PE nanofiber membrane functionalized with iminodiacetic acid by solid-phase synthesis for heavy metal ions removal
A novel hydrophilic poly(vinyl alcohol-co-ethylene) (PVA-co-PE) nanofiber membrane for heavy metal
ions removal was fabricated by the solid phase synthesis of iminodiacetic acid (IDA) on nanofiber
membrane surfaces. The hydrophilic PVA-co-PE nanofiber membranes were activated with cyanuric chloride.
The IDA was then covalently linked to the activated PVA-co-PE nanofiber membranes. The chemical
str...

[Macro. Chem. Phys.] Catalytic Precision Polymerization: Rare Earth Metal-Mediated Synthesis of Homopolymers, Block Copolymers, and Polymer Brushes
Recent studies have shown that rare earth metal-mediated group transfer polymerization
(REM-GTP) can be applied to a variety of polar monomers, besides the classic (meth)-
acrylates or (meth)acrylamides, giving access to new polymeric materials. This article
highlights progress in this new fi eld and gives a current overview of the initiation and
propagation of vinylphosphonates, the extension to ...

Construction of Response Patterns for Metal Cations by Using a Fluorescent Conjugated Polymer Sensor Array from Parallel Combinatorial Synthesis
Pattern-based strategy is an emerging field of interest for effective sensing applications. Seven different conjugated polymers from combinatorial synthesis were combined into a sensor array, and seven metal cations were selected as representative analytes. The response patterns for each cation were constructed by collecting the individual fluorescence responses from seven...

Directly Probing Molecular Ordering at the Buried Polymer/Metal Interface 2: Using P-Polarized Input Beams
Previously, we developed several methods to use sum frequency generation (SFG) vibrational spectroscopy to probe buried polymer/metal interfaces in situ by depositing polymer films with different thicknesses on metal surfaces or sandwiching a polymer thin film between a metal surface and a fused silica window. In this study, we developed a new and easier method to directly probe the polymer...

Illustrating consistency of different experimental approaches to probe the buried polymer/metal interface using sum frequency generation vibrational spectroscopy
In this paper, we demonstrate our ability to directly probe the molecular structures of the buried polymer/metal interface using sum frequency generation (SFG) vibrational spectroscopy. Spectroscopic data from different experimental approaches were compared and analyzed to deduce the molecular ordering information at a buried polymer/metal interface, i.e. the poly(n-butyl methylacrylate) (P...
