TALENT: The Renaissance of Side-Chain Ferrocene-Containing Polymers: Scope and Limitations of Vinylferrocene and Ferrocenyl Methacrylates

TALENT: The Renaissance of Side-Chain Ferrocene-Containing Polymers: Scope and Limitations of Vinylferrocene and Ferrocenyl Methacrylates

Markus Gallei

The combination of metals and polymers is an intensively explored field for the formation of so-called next-generation materials. Metal-containing polymers featuring the ferrocene motif in the side chain, such as poly(vinylferrocene) and poly(ferrocenyl methacrylates), have been known for a long time but, due to recent synthetic efforts, the first steps toward fruitful applications have only been investigated in the last few years.

TREND: "Heavy-Atom" Donor-Acceptor Conjugated Polymers

TREND: ''Heavy-Atom'' Donor-Acceptor Conjugated Polymers

Gregory L. Gibson and Dwight S. Seferos*

Donor-acceptor polymers containing "heavy" atoms below the first row of the periodic table are widely studied with an eye to organic electronics. These polymers demonstrate desirable optical and electronic properties, including high charge-carrier mobility. This article elucidates trends in heavy-atom polymer structure–property relationships by examining single atom substitutions in select donor–acceptor architectures.

TALENT: Composing Well-Defined Stimulus-Responsive Materials Through Postpolymerization Modification Reactions

TALENT: Composing Well-Defined Stimulus-Responsive Materials Through Postpolymerization Modification Reactions

Peter J. Roth

Choosing the right building blocks is the key to designing novel smart materials. This article combines theoretical fundamentals of different types of stimulus-responsiveness, emphasizing lower and upper critical solution temperature (LCST and UCST) behavior, with a range of illustrations of postpolymerization modification reactions in order to provide guidance on how to compose well-defined smart polymers with tailored properties.

TALENT: Two Non-covalent Methods to Decorate Nanoparticles with Block Copolymers

TALENT: Two Non-covalent Methods to Decorate Nanoparticles with Block Copolymers

Christophe Schatz

Two novel approaches of particle functionalization with block copolymers are introduced. The first method is based on the physical adsorption of a charged block copolymer with two adsorbing blocks. The second method consists of self-assembling a bilayer of amphiphilic block copolymer at the particle surface through a change of solvent polarity.

TREND: Polysaccharide Biocatalysis: From Synthesizing Carbohydrate Standards to Establishing Characterization Methods

TREND: Polysaccharide Biocatalysis: From Synthesizing Carbohydrate Standards to Establishing Characterization Methods

Jelena Ciric, Dejan M. Petrovic and Katja Loos*

In vitro enzymatic synthesis is the future for polysaccharide production. By synthesizing and characterizing various polysaccharides with complicated structures, they are understood better and a much closer understanding of nature is reached. The characterization of widely used natural carbohydrates, such as starch and cellulose, can be improved after a detailed analysis of their enzymatically synthesized analogs. An overview of both enzymatic synthesis and various characterization techniques of polysaccharides is presented in this article.

Functional Polymers: Synthesis and Photovoltaic Properties of a D–A Copolymer Based on the 2,3-Di(5-hexylthio­phen-2-yl)quinoxaline Acceptor Unit

Functional Polymers: Synthesis and Photovoltaic Properties of a D–A Copolymer Based on the 2,3-Di(5-hexylthio­phen-2-yl)quinoxaline Acceptor Unit

Kun Wang, Zhi-Guo Zhang, Qiang Fu,* and Yongfang Li*

A new D–A copolymer, PBDT-DTQx, based on the 2,3-di(5-hexylthiophen-2-yl)­quinoxaline (>DTQx) acceptor unit is designed and synthesized for application as a donor material in polymer solar cells (PSCs). The device based on PBDT-DTQx:PC70BM (1:2.5, w/w) with chloronaphthalene as a solvent additive displays a power conversion efficiency (PCE) of 3.15%. With methanol treatment, the PCE of the PSCs is further improved to 3.90%.

TALENT: Facile One-Pot Synthesis of New Functional Polymers through Multicomponent Systems

Shiqi Wang, Changkui Fu, Yen Wei and Lei Tao*

One-pot strategies, which combine in situ monomer synthesis and controlled radical polymerization together, are applied into innovative functional polymer preparation. This methodology is simple, efficient, and versatile. In this talent article, most advances in one-pot synthesis strategies are summarized and their further applications are discussed.

SENSORS: Monitoring Polymerization Kinetics in Microreactors by Confocal Raman Microscopy

SENSORS: Monitoring Polymerization Kinetics in Microreactors by Confocal Raman Microscopy

Arvind Kumar Yadav, Manfred Krell, Wolf-Dieter Hergeth, José Carlos de la Cal and María Jesús Barandiaran*

Use of confocal Raman microscopy to monitor kinetics of homogeneous and heterogeneous polymerizations in microreactors is being reported. The adequacy of the technique is demonstrated through several experiments performed at different residence time for solution and miniemulsion polymerizations. The method also allows getting the conversion evolution along the microreactor length by changing the position of the Raman microscope.

SENSORS: Filtrodynamics 2 - Effects of Particle Size and Filter Type on Trans-Filter Time-Dependent Pressure Signals

SENSORS: Filtrodynamics 2 - Effects of Particle Size and Filter Type on Trans-Filter Time-Dependent Pressure Signals

Marie Dufrechou, Emmanuel Mignard, Michael F. Drenski and Wayne F. Reed*

The filtrodynamic behavior of trans-filter time-dependent pressure signals is determined for membrane and frit filters using latex spheres of varying diameter D. An accretion model based on Darcy's law best describes the mechanism of membrane filters. Non-membrane metallic frits reveal a different mechanism and behavior of filtration that is better described by the "characteristic loading" model.

TREND: Mechanism and Kinetics of Dithiobenzoate-Mediated RAFT Polymerization - Status of the Dilemma

Graeme Moad

Developments in the understanding of the mechanism and kinetics of dithiobenzoate-mediated reversible addition-fragmentation chain-transfer (RAFT) polymerization over the period 2006–2013 are critically assessed with specific reference to choice of reagents and polymerization conditions, reagent and product stability, side reactions and factors that may lead to retardation.
