Polymer/Silica Nanocomposites: Preparation, Characterization, Properties, and Applications

This paper provides a third update to the review of reversible deactivation radical polymerization (RDRP) achieved with thiocarbonylthio compounds (ZC(=S)SR) by a mechanism of reversible addition-fragmentation chain transfer (RAFT) that was published in June 2005 (Aust. J. Chem. 2005, 58, 379). The first update was published in November 2006 (Aust. J. Chem. 2006, 59, 669) and the second in December 2009 (Aust. J. Chem. 2009, 62, 1402). This review cites over 700 publications that appeared during the period mid 2009 to early 2012 covering various aspects of RAFT polymerization which include reagent synthesis and properties, kinetics and mechanism of polymerization, novel polymer syntheses, and a diverse range of applications. This period has witnessed further significant developments, particularly in the areas of novel RAFT agents, techniques for end-group transformation, the production of micro/nanoparticles and modified surfaces, and biopolymer conjugates both for therapeutic and diagnostic applications.

Polymer Brushes via Surface-Initiated Controlled Radical Polymerization: Synthesis, Characterization, Properties, and Applications

Recent advances in transition metal catalyzed oxidation of organic substrates with molecular oxygen.

A facile one-step synthesis to cross-linked polymeric nanoparticles as highly active and selective catalysts for cycloaddition of CO2 to epoxides.

The amino acid Schiff base manganese complex (Sal–Phe–Mn) was prepared with l -phenylalanine, salicylaldehyde and Mn(OAc) 2 ·4H 2 O. The ligand and the complex were characterized by the infrared spectra, small area X-ray photoelectron spectroscopy, and ICP-AES. In the presence of the manganese complex, cyclohexene was effectively oxidized by molecular oxygen without reductant. The major products of the reaction were 2-cyclohexen-1-ol (–OH), 2-cyclohexen-1-one (CO) and 2-cyclohexen-1-hydroperoxide (–OOH), which was different with typical oxidation of cyclohexene. The influence of reaction temperature and additive for oxidation had been studied. The selectivity of 2-cyclohexen-1-hydroperoxide varied with reaction time and different additives. The mechanism of cyclohexene oxidation had also been discussed.

Rare earth metal ions containing polymer ternary complexes were synthesized and characterized. The functional polymers investigated were polymer-bond triphenylphosphine (PBDP), polymer-bond triphenylarsine (PBDAs), polymer-bond triphenylstibine (PBDSb), and polymer-bond triphenylbismuthine (PBDBi) as polymer ligands. Several substances, such as thenoyltrifluoroacetone (TTA), and 8-hydroxyquinoline (oxin), phenanthroline (phen) were used as low molecular weight ligands. The results show that TTA is the best low molecular weight ligand among them. The fluorescence properties of synthesized complexes were investigated; PBDAs is a better polymer ternary complex that possesses stronger fluorescence intensity coordinated with any low molecular weight ligand. The fluorescence lifetimes of Eu3+-containing polymer ternary complexes are between 0.350 and 0.469 MS. The reaction conditions of the formation and stability of rare earth metal ions–polymer–TTA ternary complexes are discussed. © 1998 John Wiley & Sons, Inc. J Appl Polym Sci 68: 1605–1611, 1998
