Aiming a better coordination among these three parts of teacher education at university, many of the supported projects have designed and realized university-specific approaches. This conference proceedings volume comprises contributions by 15 of these projects. Seven of those were introduced and discussed in workshops on the occasion of two cross-regional project-conferences in Hannover and Potsdam. Overall, the contributions give a theoretically funded as well as a practice-oriented overview of current approaches and concepts to achieve a better connection between study units concerning studies in content knowledge, pedagogical content knowledge and pedagogical knowledge in teacher education. The volume presents university projects, which take effect on different levels (at the level of curriculum and content, at a collegiate level, at the level of structural conditions of universities). The different approaches are described in a way that they can provide a basis for transfer to other subjects or further universities. The contributions are aimed at teacher educators as well as other actors working in the field of teaching- and quality development at universities. All of them can take transferable ideas and impulses from the described concepts and formats.}, language = {de} } @article{MuellerNanovaGlaseretal.2016, author = {Mueller, Lars and Nanova, Diana and Glaser, Tobias and Beck, Sebastian and Pucci, Annemarie and Kast, Anne K. and Schroeder, Rasmus R. and Mankel, Eric and Pingel, Patrick and Neher, Dieter and Kowalsky, Wolfgang and Lovrincic, Robert}, title = {Charge-Transfer-Solvent Interaction Predefines Doping Efficiency in p-Doped P3HT Films}, series = {Chemistry of materials : a publication of the American Chemical Society}, volume = {28}, journal = {Chemistry of materials : a publication of the American Chemical Society}, publisher = {American Chemical Society}, address = {Washington}, issn = {0897-4756}, doi = {10.1021/acs.chemmater.6b01629}, pages = {4432 -- 4439}, year = {2016}, abstract = {Efficient electrical doping of organic semiconductors is a necessary prerequisite for the fabrication of high performance organic electronic devices. In this work, we study p-type doping of poly(3-hexylthiophene) (P3HT) with 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F(4)TCNQ) spin-cast from two different solvents. Using electron diffraction, we find strong dopant-induced pi-pi-stacking for films from the solvent chloroform, but not from chlorobenzene. This image is confirmed and expanded by the analysis of vibrational features of P3HT and polaron absorptions using optical spectroscopy. Here, a red-shifted polaron absorption is found in doped films from chloroform, caused by a higher conjugation length of the polymer backbone. These differences result in a higher conductivity of films from chloroform. We use optical spectroscopy on the corresponding blend solutions to shed light on the origin of this effect and propose a model to explain why solutions of doped P3HT reveal more aggregation of charged molecules in chlorobenzene, whereas more order is finally observed in dried films from chloroform. Our study emphasizes the importance of solvent parameters exceeding the bare solubility of pure dopant and host material for the preparation of highly conductive doped films.}, language = {en} }
