Competition Between Energy Transfer Quenching and Chelation Enhanced Fluorescence in a Cu (II) Coordinated Conjugated Polymer System
An investigation of the mechanism of the fluorescence quenching by Cu2+ for a conjugated polymer system initially designed as a fluorescence turn-on chemosensor based on chelation enhanced fluorescence (CHEF) is described in this paper. Unlike all other metal cations tested, the polymer/Cu2+ hybrid system with a 1:1 ratio between the receptor and Cu2+ has only weak f...

Polymer Bound Glutamic Acid Salicylaldehyde Schiff-base Complex Catalyst for Oxidation of Olefins with Dioxygen
The polymer bound Schiff-base ligand (PS-SalGlu) has
been prepared from polystyrene bound salicylaldehyde
and glutamic acid, and its complex (PS-SalGlu-Co) has
also been synthesized. The polymer ligand and its
complex were characterized by infrared spectroscopy,
small area X-ray photoelectron spectroscopy, and
inductively coupled plasma-atomic emission spectro
(ICP-AFS). In the presence of ...

Effect of temperature and additives on the reactivity and product selectivity of polymer-bound nickel（II）complex
Cyclohexene was catalytically oxidized in the presence of molecular oxygen and polymer-bound nickel（II） complex PS-bipy–Ni（II）–oxine （where PS-bipy=polystyrene, bipy=2,2‘X-bipyridine） in the absence of solvent at 700C, affording 2-cyclohexen-1-ol, 2-cyclohexen-1-one and dicyclow4.1.0x-2-oxygen-heterocycloheptane in 27.5% yield. The effect of temperature, additives and the a...

Enhancement of dielectric constant and piezoelectric coefficient of ceramic–polymer composites by interface Chelation Excellent interfacial adhesion
Ferroelectric ceramics (e.g., lead zirconate titanate, PZT) and polymers exhibit extraordinary dielectric and piezoelectric properties and processability, respectively. It is, however, difficult to retain the ideal dielectric constant (εr) and piezoelectric coefficient (d33) in their composites. Here we show that an interfacial adhesion mechanism (afforded by the chelation technique...

[Small] Fabrication of Patterned Polymer Brushes on Chemically Active Surfaces by in situ Hydrogen Bond Mediated Attachment of an Initiator
The cover picture shows a 3D AFM topographic image of PNIPAAM brushes micropatterned on a COOH-functionalized, polyacrylic acid (PAA) polymer brush substrate. In this novel patterning approach, the brush substrate is first patterned with an atom transfer radical polymerization (ATRP) initiator silane, which attaches by hydrogen bond formation to the COOH species at the top of the PAA brush subst...

Fluorescence hydrogen peroxide probe based on titanium dioxide film modified microstructured polymer optical fiber
A highly sensitive microstructured polymer optical fiber (MPOF) probe for hydrogen peroxide was made by forming a rhodamine 6G-doped titanium dioxide film on the side walls of array holes in an MPOF. It was found that hydrogen peroxide only has a response to the MPOF probe in a certain concentration of potassium iodide in sulfuric acid solution. The calibration graph of fluorescence intensity vers...

Studies on Synthesis of Water-Soluble Polymer-supported Transition Metal Polypyridyl Complexes and their interaction with DNA
Five water-soluble polymer-supported transition metal polypyridyl complexes were synthesized from polyacrylic acid -co- N-vinyl pyrrolidone, 2-methyl-3-hydroxyl benzaldehyde, o-phenanthroline and metal acetate salts. Infrared spectra (IR), thermo-gravimetric and differential thermal analysis (TG-DTA), Inductance Coupling Plasma (ICP) and X-ray photoelectron spectroscopy (XPS) measurement technolog...
