  1. Dipole-field Sums, Lorentz Factors, and Dielectric Properties of Organic Molecular Films Modeled as Crystalline Arrays of Polarizable Points

    Davide Vanzo, Benjamin J. Topham and Zoltán G. Soos

    Article first published online: 22 OCT 2014 | DOI: 10.1002/adfm.201402405

    The relative permittivityκ = ε/ε0 of crystalline thin films is obtained in the limit of zero intermolecular overlap. Dipole-field sums over polarizable points in applied field E are evaluated directly and combined with Lorentz factors to compute κ from monolayers to crystals, deviations from uniform polarization in surface layers, and dielectric properties in systems of lower than cubic symmetry.

  2. An Exciplex Forming Host for Highly Efficient Blue Organic Light Emitting Diodes with Low Driving Voltage

    A novel exciplex forming host, composed of mCP and PO-T2T, is realized. Using the host and efficient energy transfer to FIrpic, unprecedented high performance blue phosphorescent OLED is demonstrated, showing a maximum EQE of 30.3%, power efficiency of 66 lm W−1, and extremely low operating voltages of 2.75 at 100 cd m−2, and 4.65 V at 10 000 cd m−2.

    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)

    Dongyoon Khim, Kang-Jun Baeg, Mario Caironi, Chuan Liu, Yong Xu, Dong-Yu Kim and Yong-Young Noh

    Article first published online: 22 OCT 2014 | DOI: 10.1002/adfm.201470261

    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.

    Lanthanides: Unraveling the Influence of Lanthanide Ions on Intra- and Inter-Molecular Electronic Processes in Fe10Ln10 Nano-Toruses (Adv. Funct. Mater. 40/2014) (page 6279)

    Amer Baniodeh, Yu Liang, Christopher E. Anson, Nicola Magnani, Annie K. Powell, Andreas-Neil Unterreiner, Simon Seyfferle, Michael Slota, Martin Dressel, Lapo Bogani and Karin Goß

    Article first published online: 22 OCT 2014 | DOI: 10.1002/adfm.201470264

    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)

    Article first published online: 22 OCT 2014 | DOI: 10.1002/adfm.201470266

    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.
