“…The thermodynamic self-assembly of a poly(ethylene oxide)-based block copolymer can also provide a template for incorporation of gold salts or nanotubes to create a self-organizing, nanocomposite electrode [97]. Bullock and Kofinas have used ionically conducting block copolymers as templates for the synthesis of lithium manganese oxide nanoparticles such that a self-assembled film functions as both a polyelectrolyte and as a composite anode in a lithium battery system [98,99].…”

The nanometer-scale architectures in thin films of self-assembling block copolymers have inspired a variety of new applications. For example, the uniformly sized and shaped nanodomains formed in the films have been used for nanolithography, nanoparticle synthesis, and high-density information storage media. Imperative to all of these applications, however, is a high degree of control over orientation of the nanodomains relative to the surface of the film as well as control over order in the plane of the film. Induced fields including electric, shear, and surface fields have been demonstrated to influence orientation. Both heteroepitaxy and graphoepitaxy can induce positional order on the nanodomains in the plane of the film. This article will briefly review a variety of mechanisms for gaining control over block copolymer order as well as many of the applications of these materials. Particular attention is paid to the potential of perfecting long-range two-dimensional order over a broader range of length scales and the extension of these concepts to functional materials and more complex architectures. #

“…Catalyst 2 was used as the initiator producing a polymer with an PDI of 2. [33] Initiator 7 and initiator 8 have already been tested for their potential in block copolymer synthesis. Both initiators, as already outlined, provide complete initiation and an outstanding functional-group tolerance and are particularly suited for block copolymer synthesis, as evidenced by a combined matrix-assisted laser desorption/ionisation mass spectroscopic, gel permeation chromatographic, and NMR spectroscopic studies of an ABC triblock cooligomer prepared by 7 (Table 5: entry 1).…”

Summary: The success of metathesis chemistry techniques has sparked a tremendous interest in polymer and material chemistry. This contribution provides an overview of the state of the art in ring opening metathesis polymerisation (ROMP). It is intended to provide the reader with useful information on the interplay of initiators, monomers, and reaction conditions, thus aiding polymer chemists to utilise the ROMP toolbox. Prominent and illustrative examples from current research are given in the article.The “ROMP toolbox”.magnified imageThe “ROMP toolbox”.

“…Kofinas et al reported on synthesis, characterization and applications of poly(NBECOOH)-based amphiphilic block copolymers. [25][26][27] As living polymerization chemists' point of view, however, the diagnostic proof for the absence of chain transfer and termination has not been clearly provided so far. So, it intrigued us to study systematically on living ROMP of NBETMS to achieve hydrophilic poly (NBECOOH) with controlled molecular weight and narrow molecular weight distribution.…”

We report the successful synthesis of poly(NBECOOH-b-NBEPOSS) copolymers, taking advantage of the sequential, living ring opening metathesis polymerization of NBETMS and NBEPOSS using the RuCl 2 (=CHPh)(PCy 3 ) 2 /CH 2 Cl 2/20 o C system, followed by the hydrolysis of trimethylsilyl groups in poly(NBETMS-b-NBEPOSS) copolymers. The living behavior of ROMP of NBETMS was first investigated using two diagnostic plots, a first order kinetic plot and a vs. conversion plot. The plots confirmed that no termination and chain transfer reaction had occurred during polymerization. Poly(NBECOOH-b-NBEPOSS) copolymers were prepared using the sequential monomer addition of NBEPOSS to living poly(NBETMS) chain ends, followed by the hydrolysis of trimethylsilyl groups in the poly(NBETMS-b-NBEPOSS) copolymers. The high structural integrity of poly(NBE-COOH-b-NBEPOSS) copolymers was confirmed by 1 H-NMR, 1 3 C-NMR spectroscopy and GPC.
