Dr. Manfred Wagner

Manfred Wagner studied chemistry at the University of Mainz. He  received his Diploma in 1988 in the group of Prof. Dr. K. Müllen. In  1993, he obtained his Ph.D. at the Max Planck Institute for Polymer  Research for his work on the synthesis of band structures and their  physical properties.  Since 1988, he has been head of the High-Resolution NMR Spectroscopy  Service Group. His research interests include the clarification of  small molecules and polymeric structures with multi-dimensional NMR  methods.  His current research activities concentrate on 1) the use of gradient- field NMR to study the diffusional behavior of oligomers and polymers  in solution, 2) heteronuclear NMR investigations like 31P, 19F, 29Si, 11B etc.  measurements  to understand the microstructures of copolymers  and 3) the LC- NMR for the compositional dependence of copolymers as a  function of molecular weight.

Research Topics

1. Functional pi-conjugated molecules (NMR characterization):  polycyclic aromatic hydrocarbons, heteroatom-containing nanographenes and macrocycles

2. High Resolution NMR Spectroscopy: hydrodynamic radius, copolymerisation characterization, one- and two- dimensional NMR, high-and low-temperature measurements, heteronuclear NMR, investigation, LC-NMR investigations

Dr. Wojciech Pisula

Dr. Wojciech Pisula studied chemical engineering (1996-2001) at the University of Applied Science Osnabrück and at the University of Wales, Swansea, where he gained his Master of Science. During his diploma thesis, he worked on the compatibilization of various blends of immiscible polymers in the group of Professor Jacek Piglowski at the Technical University of Wrocław in the Institute for Organic Technology and Synthetic Materials in collaboration with Professor Claudia Kummerlöwe at the University of Applied Sciences Osnabrück. In 2001, he joined the group of Professor Klaus Müllen at the Max Planck Institute for Polymer Research, where he completed his dissertation in 2005. There, he focused on the control of the supramolecular self-organization of discotic liquid crystalline polycyclic aromatic hydrocarbons with a strong interest in their application in electronic devices. During this time, he worked in the Department of Polymer Physics under the supervision of Professor Tadeusz Pakula. In 2006 he changed to a full position in industry (Evonik AG, former Degussa), keeping in the same time his status as researcher at the MPIP. His research interests are physical chemical aspects of π-conjugated self-organizing systems and their applications in organic electronics. For more details see research topics.

Research Topics

1) Structural investigation:

Temperature-dependent investigation of supramolecular structures of Π-conjugated self-assembly systems in bulk by fiber 2D- and in thin film by grazing incidence wide/small-angle X-ray scattering. Analysis of experimental data is verified by Cerius2simulations.

2) Organic field-effect transistors:

Fabrication of OFETs based on Π-conjugated polymers and small molecules and device optimization by interface modification. Understanding of the relation between molecular architecture, long-range order and macroscopic electronic properties. Development of transistors in mesoscopic dimensions.

3) Control of self-assembly:

Modification of the self-organization of functional molecules on surfaces under various processing conditions from solution, from the isotropic melt or from their mesophase. Control over their microstructure and molecular arrangement towards the surface and the correlation to charge carrier transport in devices.

4) New processing techniques:

Development of novel processing methods. Uniaxial, long-range molecular orientation in thin films under non-equilibrium for device improvement.
