The crystal structure for 2,5-di(p-tolyl)-1,3,4-oxadiazole (DTO) differs from that of 2,5-di (4-methoxycarbonyl-phenyl)-1,3,4- oxadiazole (DMPO). In DMPO all molecules show parallel orientation to the surface in such a way that the surface is formed as well as by the nitrogen atoms of the heterocyclic rings and the methyl groups of the ester substituents. By contrast, the oxadiazole molecules in DTO crystals are oriented perpendicular to the crystal surface. The experimental data are interpreted by molecular modelling. It is shown that there is a difference between molecular structure of the surface, as detected by AFM, and the bulk structure determined by X-ray diffraction.}, language = {en} } @article{SchulzStillerZetzscheetal.1994, author = {Schulz, Burkhard and Stiller, Burkhard and Zetzsche, Thomas and Knochenhauer, Gerald and Dietel, Reinhard and Brehmer, Ludwig}, title = {Crystal structure of 2,5-Di(4- methoxycarbonyl-phenyl)-1,3,4-oxadiazole characterized by AFM and IR- spectroscopy}, year = {1994}, language = {en} } @article{ReicheFreydankDietzeletal.1995, author = {Reiche, J{\"u}rgen and Freydank, A. and Dietzel, Birgit and Katholy, Stefan and Knochenhauer, Gerald and Zetzsche, Thomas and Schulz, Burkhard and Brehmer, Ludwig}, title = {Komplexe Strukturanalytik von Oxadiazol-Mono- und Multischichten}, year = {1995}, language = {de} } @article{BrehmerDietzelFreydanketal.1995, author = {Brehmer, Ludwig and Dietzel, Birgit and Freydank, Anke-Christine and Katholy, Stefan and Knochenhauer, Gerald and Reiche, J{\"u}rgen and Schulz, Burkhard and Zetzsche, Thomas}, title = {Langmuir- und Langmuir-Blodgett-Filme amphiphiler Oxadiazole}, year = {1995}, language = {de} } @article{DietzelFreydankReicheetal.1995, author = {Dietzel, Birgit and Freydank, A. and Reiche, J{\"u}rgen and Brehmer, Ludwig and Knoblauch, H. and Knochenhauer, Gerald and Zetzsche, Thomas}, title = {Mono- und Multischichten von neuen aromatischen 1,3,4-Oxadiazolen}, year = {1995}, language = {de} } @article{PenacoradaReicheDieteletal.1996, author = {Penacorada, Florencio and Reiche, J{\"u}rgen and Dietel, Reinhard and Zetzsche, Thomas and Stiller, Burkhard and Knobloch, Harald and Brehmer, Ludwig}, title = {Monolayers and multilayers of uranyl arachidate : 2.

The pH range of the acid to salt conversion determined for the Langmuir films is confirmed by the infrared spectroscopic data of the multilayers. While arachidic acid films, deposited from an uranyl acetate subphase of low pH, are found to have strongly distorted rough surface, the films of uranyl structure, The influence of the counterions on the alkyl chain conformation, chain packing, reorganization probability, and stability of the multilayer is discussed.}, language = {en} } @article{ReicheZetzscheHelmsetal.1997, author = {Reiche, J{\"u}rgen and Zetzsche, Thomas and Helms, Andreas and Freydank, Anke-Christine and Knochenhauer, Gerald and Schulz, Burkhard and Brehmer, Ludwig}, title = {Organized molecular films of oxadiazole compounds formed by vacuum deposition}, year = {1997}, language = {en} } @article{ReichePenacoradaZetzscheetal.1995, author = {Reiche, J{\"u}rgen and Penacorada, Florencio and Zetzsche, Thomas and Katholy, Stefan and Brehmer, Ludwig}, title = {Polyelektrolyt-Fetts{\"a}ure-Multiphasen-LB-Schichten}, year = {1995}, language = {de} } @article{SchulzBrehmerDietzeletal.1995, author = {Schulz, Burkhard and Brehmer, Ludwig and Dietzel, Birgit and Zetzsche, Thomas}, title = {Preparation and characterization of ordered thin films based on aromatic poly(1,3,4-oxadiazole)s}, year = {1995}, language = {en} }
