- Temperature-Dependent Evolution of Poly(3-Hexylthiophene) Type-II Phase in a Blended Thin Film
Si Woo Lee, Hee-Sung Keum, Han Seong Kim, Hyo Jung Kim, Kwangseok Ahn, Dong Ryeol Lee, Je Han Kim and Hyun Hwi Lee

Type-II (or type II-like) P3HT phase is formed in P3HT:PCBM films on a poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) substrate by cryogenic cooling to low temperature (−143 °C) followed by gradual heating to room temperature. The formation of type-II P3HT was largely enhanced by the presence of the upper Al electrode layer. Concomitant with the formation of the type-II phase, a 1:3 ordered P3HT type-II (1/3,0,0) superlattice peak emerges.
- Radical Chain Polymerization Catalyzed by Graphene Oxide and Cooperative Hydrogen Bonding
Zhongcheng Zhu, Shengjie Shi and Huiliang Wang

Graphene oxide (GO) can function as a catalyst to accelerate the radical chain polymerizations of acrylic acid (AA), as indicated by the much enhanced overall kinetic rate constants and lowered activation energies. The catalytic effect of GO for the polymerization of AA is due to the acidic nature of GO and the hydrogen bonding interactions between GO and monomer molecules and/or polymers.
- Single-Chain Folding of Synthetic Polymers: A Critical Update
Ozcan Altintas and Christopher Barner-Kowollik
Article first published online: 23 NOV 2015 | DOI: 10.1002/marc.201500547
The synthesis and characterization of single-chain nanoparticles based on well-defined functional linear synthetic macromolecules via selective point folding as well as repeat unit folding are critically discussed via selected recent examples.
- Living ROMP Synthesis and Redox Properties of Diblock Ferrocene/Cobalticenium Copolymers
Roberto Ciganda, Haibin Gu, Patricia Castel, Penxiang Zhao, Jaime Ruiz, Ricardo Hernández and Didier Astruc
Article first published online: 23 NOV 2015 | DOI: 10.1002/marc.201500566
Using the third-generation Grubbs catalyst, the living ring-opening metathesis polymerization of ferrocenyl/cobalticenium copolymers is conducted with theoretical numbers of 25 monomer units for each block, and their redox and electrochemical properties allow using the Bard–Anson electrochemical method to determine the number of metallocenyl units in each block.
- “Click” Incorporation of Radical/Ionic Sites into a Reactive Block Copolymer: A Facile and On-Demand Domain Functionalization Approach toward Organic Resistive Memory
Takeo Suga, Kohei Aoki, Toshiaki Yashiro and Hiroyuki Nishide
Article first published online: 19 NOV 2015 | DOI: 10.1002/marc.201500492
Click amidation of a reactive block copolymer bearing a pentafluorophenyl ester group with 2,2,6,6-tetramethylpiperidine-N-oxyl- and imidazolium-functionalized amines provides the installation of statistical radical- and ionic sites into the reactive segment. Monolayer devices fabricated with the obtained block copolymers reveal that the coexistence of radicals and ions in the same spherical domain is a prerequisite for repeatable switching memory.
