    1. Templated Organic and Hybrid Materials for Optoelectronic Applications (pages 1146–1166)

      Niko Haberkorn, Maria C. Lechmann, Byeong Hyeok Sohn, Kookheon Char, Jochen S. Gutmann and Patrick Theato

      Version of Record online: 3 JUL 2009 | DOI: 10.1002/marc.200900213

      This review compiles different approaches to template organic materials as well as hybrid materials that find application in optoelectronic devices. Two templating approaches are presented and discussed in detail, e.g. the use of preformed nanoporous membranes as templates for organic materials, and self-assembly processes of materials to pattern hybrid materials. Both routes are very promising templating approaches for optoelectronic materials and represent complementary rather than competing techniques.

    2. Electrical Modes in Scanning Probe Microscopy (pages 1167–1178)

      Rüdiger Berger, Hans-Jürgen Butt, Maria B. Retschke and Stefan A. L. Weber

      Version of Record online: 7 JUL 2009 | DOI: 10.1002/marc.200900220

      Thumbnail image of graphical abstract

      The major scanning probe microscopy modes that are used for electrical characterization of thin films are reviewed: scanning conductive force microscopy, Kelvin probe force microscopy and scanning electric field microscopy. To demonstrate the possibilities and capabilities of these modes, reference samples, fabricated by means of focused ion beam deposition, are characterized. Knowledge of the local electrical properties becomes more and more important with further reductions in size of electronic elements and using nanocomposite materials.

    3. Liquid Crystalline Ordering and Charge Transport in Semiconducting Materials (pages 1179–1202)

      Wojciech Pisula, Matthias Zorn, Ji Young Chang, Klaus Müllen and Rudolf Zentel

      Version of Record online: 7 JUL 2009 | DOI: 10.1002/marc.200900251

      Understanding energy transfer in small organic molecules and conjugated polymers is a prerequisite for the design of novel materials for organic optoelectronics. Bulk as well as single molecule studies of energy transfer yield information which ultimately will help to optimize device structures.

    1. Tunable Phosphorescent Emission through Energy Transfer within Multilayer Thin Films Based on a Carbazole-Based Host and Ir(III)-Complex Guest System (pages 1232–1237)

      Hosub Kim, Yi-Yeol Lyu, Kyungsun Choi, Rudolf Zentel, Soo-Hyoung Lee and Kookheon Char

      Version of Record online: 2 JUN 2009 | DOI: 10.1002/marc.200900023

      Thumbnail image of graphical abstract

      Tunable phosphorescent emission properties such as intensity and color are realized by control of energy transfer between different colored Ir(III)-complexes and a carbazole-based host material in multilayer thin films prepared by the spin-assisted layer-by-layer method. The fine tuning of emission properties is achieved by adding a non-emitting spacer layer between the Ir(III)-complex and host material of nanometer range.

    2. Surface Coatings Based on Polysilsesquioxanes: Solution-Processible Smooth Hole-Injection Layers for Optoelectronic Applications (pages 1238–1242)

      Daniel Kessler, Maria C. Lechmann, Seunguk Noh, Rüdiger Berger, Changhee Lee, Jochen S. Gutmann and Patrick Theato

      Version of Record online: 30 JUN 2009 | DOI: 10.1002/marc.200900196

      Thumbnail image of graphical abstract

      Poly(methylsilsesquioxane)–poly(N,N-di-4-methylphenylamino styrene) (PMSSQ–PTPA) as potential hole-injection layer (HIL) forming material was used for effective planarization of the anode interface. The obtained HIL showed high stability and adhesion even after several solvent treatments.

    3. Semiconductor Dendritic-Linear Block Copolymers by Nitroxide Mediated Radical Polymerization (pages 1243–1248)

      Andreas S. Lang, Franz René Kogler, Michael Sommer, Ulrich Wiesner and Mukundan Thelakkat

      Version of Record online: 3 JUL 2009 | DOI: 10.1002/marc.200900203

      Thumbnail image of graphical abstract

      In the search for novel architectures for organic semiconductors we synthesized a hybrid diblock copolymer with p-type dendritic and n-type linear block by nitroxide mediated radical polymerization (NMRP). The dendritic alcohol was first functionalized with a TIPNO derivative followed by polymerization of perylene bisimide acrylate. The feasibility of this approach as well as various properties of the resulting block copolymer are given here.

    4. Polymerizable Well-Defined Oligo(thiophene amide)s and their ROMP Block Copolymers (pages 1249–1257)

      Stefan Hilf, Johannes Klos, Kookheon Char, Heeje Woo and Andreas F. M. Kilbinger

      Version of Record online: 7 JUL 2009 | DOI: 10.1002/marc.200900207

      Oligothiophene amides constitute a new class of chromophores with potential for optoelectronic applications. Here we describe the synthesis of defined oligothiophene amides using conventional coupling chemistry. π-Conjugation across the amide linkages is shown using optical spectroscopy. Norbornene substitution of the oligomers gives easy access to the corresponding polymers via ROMP.

    5. Amorphous Carbazole-based (Co)polymers for OFET Application (pages 1258–1262)

      Benjamin Souharce, Christof J. Kudla, Michael Forster, Jürgen Steiger, Ralf Anselmann, Heiko Thiem and Ullrich Scherf

      Version of Record online: 7 JUL 2009 | DOI: 10.1002/marc.200900214

      Thumbnail image of graphical abstract

      Here we present the synthesis and characterization of poly[9-(4-alkylphenyl)carbazole-3,6-diyl] and poly[1,3-bis(3′-alkylcarbazole-9′-yl)-5-alkylphenylene-6′,6″-diyl]. The amorphous solid state structure, reasonably good field effect mobility and on/off ratios of these novel carbazole-based polymers make them promising candidates as hole conducting materials for printed organic field-effect transistors (OFETs).

    6. Relationship of Photophysical Properties and the Device Performance of Novel Hybrid Small-Molecular/Polymeric Solar Cells (pages 1263–1268)

      Sahika Inal, Mauro Castellani, Alan Sellinger and Dieter Neher

      Version of Record online: 13 JUL 2009 | DOI: 10.1002/marc.200900221

      Thumbnail image of graphical abstract

      A novel vinazene-based electron-accepting compound is analyzed photophysically in conjunction with the donor poly(3-hexylthiophene). Excited-state dynamics reveal emission from excitons and excimers on the acceptor and both types of excitations are strongly quenched in highly-intermixed bulk heterojunction systems. Interestingly, thermally-induced changes of the nanomorphology have little effect on the photovoltaic properties, while separating the donor and acceptor component on a larger scale raises the fill factor to 60%.

    7. Real Time Investigation of the Interface between a P3HT:PCBM Layer and an Al Electrode during Thermal Annealing (pages 1269–1273)

      Hyo Jung Kim, Hyun Hwi Lee and Jang-Joo Kim

      Version of Record online: 30 JUN 2009 | DOI: 10.1002/marc.200900224

      Thumbnail image of graphical abstract

      The interface between the Al electrode and the organic active layer in P3HT: PCBM-based organic photovoltaic devices is investigated using synchrotron X-rays. Thermal annealing induces the diffusion of Al into the organic layer to reduce the contact resistance and the preferred alignment of the (100) direction of the P3HT crystals from the surface normal direction, which results in an improved performance of the solar cells.

    8. Hetero-Telechelic Dye-Labeled Polymer for Nanoparticle Decoration (pages 1274–1278)

      Peter J. Roth, Ki-Se Kim, Su Hak Bae, Byeong-Hyeok Sohn, Patrick Theato and Rudolf Zentel

      Version of Record online: 3 JUL 2009 | DOI: 10.1002/marc.200900254

      A PMMA with a methyl disulfide and a fluorescent dye end group, synthesized by the RAFT process was used to functionalize the surfaces of gold nanoparticles and of CdSe/ZnS quantum dots. The fluorescence of the dye was quenched when tethered to gold nanoparticles, while quantum dots caused an increased dye emission.

    9. Conjugated Triphenylene Polymers for Blue OLED Devices (pages 1279–1283)

      Moussa Saleh, Young-Seo Park, Martin Baumgarten, Jang-Joo Kim and Klaus Müllen

      Version of Record online: 3 JUL 2009 | DOI: 10.1002/marc.200900332

      Thumbnail image of graphical abstract

      Blue-emitting conjugated triphenylene-based polymers have been synthesized using the microwave-assisted Suzuki– Miyaura and Yamamoto polycondensation reactions. All polymers showed deep- blue emission in films with PL maxima around 430 nm. The device performance in terms of luminescence efficiency, power efficiency, turn-on voltage, and electroluminescence present all polymers as good candidates for polymer organic light emitting diodes.
