- Organic Electronics: Control of Ambipolar and Unipolar Transport in Organic Transistors by Selective Inkjet-Printed Chemical Doping for High Performance Complementary Circuits (Adv. Funct. Mater. 40/2014) (page 6245)

Selective tuning the operation mode of organic transistors from ambipolar to unipolar by using molecular doping is reported by Y. Xu, D.-Y. Kim, Y.-Y. Noh, and colleagues on page 6252. The ink-jet printed dopants do not degrade device properties but rather distinctively alter the ambipolar operation to be either n-channel or p-channel with greater performance and stability. Complementary high-performance inverters incorporating only one organic semiconductor and two different dopants are succeeded.

On page 6280, A. K. Powell, A.-N. Unterreiner, K. Goß, and co-workers report an investigation of both intra- and intermolecular electron transfer processes in a family of nanotoroidal Fe(III)10Ln(III)10 cyclic coordination clusters. Photo-induced intramolecular electron transport proceeds via exciton formation on the oxygen bridges. Intermolecular tranport is rationalized using a hopping model. In both cases, the Kramers parity of the lanthanide ion is important.
- Conjugated Polymers: Systematic Investigation of Side-Chain Branching Position Effect on Electron Carrier Mobility in Conjugated Polymers (Adv. Funct. Mater. 40/2014) (page 6404)

Polymer field-effect transistors have gone through rapid development. Nevertheless, charge transport mechanism and structure–property relationship are not well understood. On page 6270, J.-Y. Wang, J. Pei, and co-workers use strong electron-deficient benzodifurandione-based poly(p-phenylene vinylene) (BDPPV) as the polymer backbone and develop six BDPPV-based polymers with various side-chain branching positions to systematically study the side-chain effect on device performance.
- Piezoelectrics: Layer-by-Layer Controlled Perovskite Nanocomposite Thin Films for Piezoelectric Nanogenerators (Adv. Funct. Mater. 40/2014) (page 6246)

Perovskite nanoparticle-based nanocomposite thin films composed of oleic acid-stabilized BaTiO3 nanoparticles and poly(acrylic acid) are prepared by S.-W. Kim, J. Cho, and team on page 6262 using ligand exchange layer-by-layer assembly in organic media. The resultant nanocomposite films with high dielectric constant and low leakage current exhibit ferroelectric and piezoelectric properties that could be exactly controlled by the bilayer number, the type of inserted polymer, and the nanoparticle size.
