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...

[JPS Part A] Poly(vinylphosphonate)s functionalized polymer microspheres via rare earth metal-mediated group transfer polymerization
We demonstrate a facile, yet efficient method for the
functionalization of crosslinked polystyrene (PS) microspheres
with biocompatible poly(vinylphosphonate)s via the combination
of a UV grafting polymerization and a surface-initiated group
transfer polymerization. Self-initiated photografting and photopolymerization
of ethylene glycol dimethacrylate results in direct
photografting of poly(ethyle...

Nanostructured Metal/Carbon Composites from Heterobimetallic Block Copolymers with Controlled Magnetic Properties
We reported the utilization of a series of heterobimetallic diblock copolymers to prepare different iron?cobalt/carbon and iron?cobalt phosphide/carbon magnetic materials. Through the control of compositions of ferroceneand cobaltocenium-containing blocks, a transition of final inorganic materials from metal phosphide to metal alloy was observed. These metal eleme...

Preparation of Graphene-Oxide/Polyamidoamine Dendrimers and Their Adsorption Properties toward Some Heavy Metal Ions
Graphene oxide/polyamidoamine dendrimers (GO/PAMAMs)were prepared via a “grafting to” method. The adsorption behavior of the GO/PAMAMs for Pb(II), Cd(II), Cu(II), and Mn(II) was studied, and the effects of solution pH, adsorption time, and initial metal ion concentration on adsorption capacity of the adsorbent were also investigated. The pseudo-first-order and pseudo-second-order ...

Modification of Metal Complex on Hydrogenation of o-Chloronitrobenzene over Polymer-stabilized Platinum Colloidal Clusters
The effect of metal complex on hydrogenation of o-chloronitrobenzene CNB. over poly-vinylpyrrolidone-stabilized platinum clusters PVP-Pt. has been studied in methanol at 303 K and atmospheric pressure. The addition of metal complexes to the catalytic system can considerably modulate both the activity and the selectivity of the catalyst. A low activity 0.41 mol H2rmol Pt s. and low selectivity ...

A facile method for synthesis of Fe3O4@Polymer microspheres and their application as magnetic support for loading metal nanoparticles
In this Article, a facile and general method was afforded to prepare magnetite/polymer coreshell microspheres. The hydrogen bond interaction between the magnetite and a series of functional monomers was strong enough for coating polymer shells onto the magnetite microspheres. Various functional shells such as carboxyl, hydroxyl, amide, and ester were provided via the tune of the monomer during th...

Hybrid Nanorattles of Metal Core and Stimuli-Responsive Polymer Shell for Confined Catalytic Reactions
Narrowly-dispersed silver@silica@poly(methacrylic acid) (Ag@SiO2@PMAA) core–double shell hybrid nanoparticles (NPs) were first synthesized by distillation–precipitation polymerization, using silver@silica core–shell NPs from the sol–gel reaction as templates. Selective removal of the inorganic silica inner-shell from the Ag@SiO2@PMAA core–double shell hybrid NPs by HF etching produces the Ag@...

Multicarboxylic hyperbranched polyglycerol modified SBA-15 for the adsorption of cationic dyes and heavy metal ions from aqueous media
The aim of the present work was to investigate the potential of multicarboxylic hyperbranched polyglycerol
(HPG) modified mesoporous SBA-15 (SBA/HPG-COOH) as adsorbent for the removal of cationic dyes
or/and heavy metal ions from aqueous media. The SBA/HPG-COOH adsorbents can be facilely synthesized
through two steps: in situ anionic ring-opening polymerization of glycidol and further modification...
