June 18, 2013 TALENT: Tailoring Cellulose Surfaces by Controlled Polymerization Methods 
Anna Carlmark
To expand the utilization of cellulose beyond its traditional uses, it is necessary to modify the surface of the fibers. This paper summarizes the modification of cellulose by controlled polymerization methods such as ATRP, RAFT, ROP, and ROMP. The combination of the excellent properties of cellulose with functional polymers creates new materials of great potential in advanced material applications.

A new copolymer is designed and synthesized, and the photovoltaic performance is optimized with fullerene acceptors. The energy loss and the increase in the observed open-circuit voltages are quantitatively explained by the up-shifted lowest unoccupied molecular level of indene-C60 bisadduct (ICBA) and the reduced saturation current in the blends.

Martin Ruff,* Reinhold W. Lang, Christian Paulik
The effects of multi-stage (slurry) polymerization on mechanical properties of in-reactor blended UHMW-PE materials is presented, and it is shown that due to a controlled polymerized particle morphology, mechanical properties, such as impact properties can be regulated.

Tailoring of the optical and mechanical properties of bisterpyridine coordination polymers is enabled by the introduction of well-defined polymeric side chains. The resulting metallopolymers exhibit improved solubility and processability and can, therefore, easily be inkjet-printed. The photophysical properties of the so-produced homogeneous films are investigated and a proof-of-principle polymer light-emitting device can be constructed.

The activity of Ziegler–Natta catalysts for ethylene polymerization is studied, and a method developed to extract meaningful kinetic parameters from experimental data. Four model parameters are required to reproduce polymerization rate profiles for a range of laboratory experimental conditions.

Inchan Kwon,* Sung In Lim
Two distinct strategies, residue-specific and site-specific incorporation, allow biosynthesis of a protein containing non-natural amino acids. Non-natural amino acids introduced into a protein can be used to manipulate spectral and catalytic properties of a protein and provide new protein chemistries for bioconjugation with versatile molecules.

Kimberly B. Shepard, Rodney D. Priestley*
Matrix-assisted pulsed laser evaporation (MAPLE) is used to deposit thin films of a vast range of macromolecules, including polymers, proteins, and composite materials. The numerous advantages of MAPLE are discussed, and recent reports of MAPLE-deposited films for electronic and medical applications are highlighted.

January 31, 2013 Functional Polymers: Morphology and Field-Effect Transistor Characteristics of Electrospun Nanofibers Prepared From Crystalline Poly(3-hexylthiophene) and Polyacrylate Blends 
Chih-Chieh Chou, Hung-Chin Wu, Chih-Jung Lin, Ebrahim Ghelichkhani, Wen-Chang Chen*
Nanofiber field-effect transistors (FETs) based on crystalline poly(3-hexylthiophene) (P3HT) and poly(stearyl acrylates) (PSA) or poly(n-lauryl acrylate) (PnLA) blends are fabricated via coaxial electrospinning (ES). The maximum FET mobility is obtained for P3HT/PSA (1:0.2) blends. The crystalline PSA promotes the larger crystallinity of P3HT in the ES nanofibers, which subsequently leads to the observation of higher mobility and improves the air stability.

Jean-Rémi Pouliot, Lauren G. Mercier, Samuel Caron, Mario Leclerc*
The direct heteroarylation polymerization methodology was adapted for the diketopyrrolopyrrole moiety, giving rise to copolymers that were difficult to obtain from standard Stille or Suzuki couplings. These new low-bandgap polymers proved to be efficient electron-transporting materials enabling possible applications in all-plastic solar cells.

Zhao Li,* Patrick Malenfant, Ye Tao, Jianfu Ding*
A new alternating conjugated polymer, PDTTTPD, based on electron-rich dithieno[3,2-b:2',3'-d]thiophene (DTT) and electron-deficient thieno[3,4-c]pyrrole-4,6-dione (TPD) building block is designed and synthesized. PDTTTPD shows strong thermochromic effect in chlorobenzene solution and modest PCE of 2.1% in organic solar cell devices due to the steric hindrance induced twisting of the conjugated main chain. A general design rule is then suggested to control the main chain conformation of polymer materials for photovoltaic applications.

Chao Tang*, Xu-Dong Liu, Feng Liu, Xu-Liang Wang, Hui Xu, Wei Huang*
Polymer white light-emitting diodes (PWLEDs) are one of the most intensively researched topics in PLED. At present, there are two main methods to realize white emission in PLED. The one is to dope the host with different guests with different color, and the other is to prepare single white polymer by designing the molecular structure. Improving the performance of PWLED depends on the understanding of materials structure and properties, materials purification, and device engineering.
