Comicellization Kinetics of Block Copolymers with Different Block Lengths.

Nanolithography: Painting with block copolymers.

news & views can be resolved with a spatial resolution of ~20 nm. Furthermore, the potential for high-resolution magnetic imaging is demonstrated by resolving Abrikosov vortices with 120 nm minimum lateral distance in a Nb thin film at B ~0.2 T (Fig. 1b). The combination of high spatial sensitivity with high bandwidth suggests the approach could have a range of exciting applications including t...

Micellization of block copolymers

This article deals with recent progress including the author’s work in the field of block copolymer self-assembly in solution and on solid surfaces. The synthesis methods for producing block copolymers with well-defined structures, molecular weights and composition are outlined with emphasis on ionic and controlled free radical polymerization techniques. A general overview of the preparation, c...

Supramolecular Conjugated Block Copolymers

While the performance of polymer−polymer bulk heterojunction organic photovoltaics (OPVs) is poor compared with polymer−fullerene OPVs, reducing or eliminating micrometer-scale phase separation in all-polymer OPVs may dramatically improve performance. Herein, we demonstrate that 2-ureido-4[1H]-pyrimidinone (UPy) quadruple hydrogen bonding interactions can be used to prevent micrometer-scale pha...

Ambient-temperature living anionic polymerization of phosphaalkenes: homopolymers and block copolymers with controlled chain lengths.

Photoinduced ordering of block copolymers.

Photoinduced ordering of disordered block copolymers (BCPs) would provide an on-demand, nonintrusive route for formation of well-ordered nanostructures in arbitrarily defined regions of an otherwise disordered material. Here we achieve this objective using a rapid and simple approach in which photoconversion of an additive blended with the BCP introduces strong interactions between the additive...
