If I were not a scientist, I would miss something very essential in my life. If I won the lottery it wouldn't change much in my luck. When I'm frustrated, I do sports or make music. The most important thing I learned from my parents is sincerity. My favorite place on earth is at the “Osterseen” south of Munich. I chose chemistry as a career because at the age of ten I was boundlessly fascinated when my older brother brought sulfur home from school and said “this is a chemical—it is made up of atoms!” My most exciting discovery to date has been the suggestive power of words. My worst nightmare would be losing my optimism. My biggest motivation is supported by my confidence to change things and to be involved in shaping the future. I lose track of time when I'm having a good conversation, playing my guitar, or working undisturbed and without time pressure. Guaranteed to make me laugh is my wife's humor. The best advice I have ever been given is learning to enjoy the moment and to be happy in it. I am specifically attracted by authenticity. My favorite author (fiction) is Frank Goosen. My top three films of all time are Toni Erdmann, Lost in Translation, Tenacious D. My favorite song is Goin' Ahead from Pat Metheny's album 80/81. My favorite saying is “the highest form of bliss is living with a certain degree of folly”. My favorite piece of research is extremely narrow-band red-light-emitting Eu2+-doped luminescent materials crystallizing in variants of the UCr4C4 structure type (see Nat. Mater. 2014, 13, 891). This publication turned out to be particularly trendsetting for a systematic search targeting narrow-band luminescent materials. What does winning this award from the GDCh mean to you and your research? The Liebig Memorial Medal is the oldest scientific prize from the GDCh. Famous scientists from all areas of chemistry have been honored with this distinction. Among the previous laureates are my scientific great-grandfather Wilhelm Klemm, the predecessor of my chair here at the LMU Armin Weiß, as well as many other esteemed chemists. From 1852 until his death, Justus Liebig was professor at the University of Munich. Without any doubt, he was one of the most influential and trendsetting scientists in the early days of modern chemistry. This is also documented by the huge number of scholars that can be traced back to Liebig. By structure elucidation of carbon nitride type precursor compounds melam, melem, and melon, that were named by Justus Liebig in the 1830s, we were able to directly follow up his research. In our Department of Chemistry at the LMU, Justus Liebig is omnipresent as our greatest lecture hall bears his name. What do you think the future holds for your field of research? In most cases, the synthesis of nitrides is much more difficult and challenging compared to oxides. However, recent achievements in high-pressure synthesis (diamond anvil cells, multianvil technique, hot-isostatic presses, ammonothermal method) could overcome decisive synthetic limitations. This development has allowed a plethora of unexplored novel nitride compounds to become accessible. From classical structural ceramics of simple nitrides (e.g., Si3N4, sialones) the main focus now addresses functional materials that may find application as semiconductors, optical materials (e.g. luminescent or nonlinear optical materials for second harmonic generation) or ionic conductors. For industrial applications, crystal growth of innovative nitride materials will be fostered by the ammonothermal method. My five top papers: 1“United in Nitride: The Highly Condensed Boron Phosphorus Nitride BP3N6”: S. Vogel, A. T. Buda, W. Schnick, Angew. Chem. Int. Ed. 2018, 57, 13202; Angew. Chem. 2018, 130, 13386. Innovative and generalizable synthetic approach leading to (mixed) nonmetal nitrides starting from reactive precursors and employing the multianvil technique. The polymeric nitride BP3N6 is formed in the presence of large amounts of HCl, which supports formation of surprisingly large and well-developed single crystals. 2“Open-Shell 3d Transition Metal Nitridophosphates MIIP8N14 (MII=Fe, Co, Ni) by High-pressure Metathesis”: S. D. Kloß, O. Janka, T. Block, R. Pöttgen, R. Glaum, W. Schnick, Angew. Chem. Int. Ed. 2018, https://doi.org/10.1002/anie.201809146; Angew. Chem. 2018, https://doi.org/10.1002/ange.201809146. A more than 20 year old goal came true: synthesis of a highly condensed nitridophosphate containing open-shell transition metals. Besides this successful synthesis, the ligand-field strength of nitride ligands was quantified on the basis of spectroscopic data using angular-overlap modelling. 3“Unmasking Melon by a Complementary Approach Employing Electron Diffraction, Solid-State NMR Spectroscopy and Theoretical Calculations—Structural Characterization of a Carbon Nitride Polymer”: B. V. Lotsch, M. Döblinger, J. Sehnert, L. Seyfarth, J. Senker, O. Oeckler, W. Schnick, Chem. Eur. J. 2007, 13, 4969. In the 1830s, Justus Liebig investigated HC2N3 which he denoted “melon”. We were able to elucidate its crystal structure, confirming a polymeric character that renders melon a poly(heptazine amide imide). Our results confirm that in a multitude of prior publications melon-type polymers were erroneously interpreted as graphitic carbon nitride g-C3N4. 4“High-Pressure Synthesis of γ-P3N5 at 11 GPa and 1500 °C in a Multianvil Assembly: A Binary Phosphorus(V) Nitride with a Three-Dimensional Network Structure from PN4 Tetrahedra and Tetragonal PN5 Pyramids”: K. Landskron, H. Huppertz, J. Senker, W. Schnick, Angew. Chem. Int. Ed. 2001, 40, 2643; Angew. Chem. 2001, 113, 2713. Our research group has been investigating phosphorus(V) nitride since 1987. It took more than 10 years before we succeeded in elucidating the structure of α-P3N5. Three years later, we discovered the high-pressure form γ-P3N5 of this fundamental nonmetal nitride. Its structure is consistent with the pressure-coordination rule. Besides PN4 tetrahedra, γ-P3N5 contains PN5 pyramids which were unprecedented in P/N compounds. 5“Luminescence in Eu2+-doped Ba2Si5N8: Fluorescence, Thermoluminescence, and Upconversion”: H. A. Höppe, H. Lutz, P. Morys, W. Schnick, A. Seilmeier, J. Phys. Chem. Solids 2000, 61, 2001. Eu2+-doped nitridosilicates paved the way to robust and efficient red LED luminophores. Nowadays, members of the so-called 258-phosphors (i.e., M2Si5N8:Eu2+ with M=Sr, Ba) are being applied in numerous warm-white LEDs, signal lamps, or turn indicators. Thus, these materials find broad application in cars and smartphones, as well as in general lighting devices. Volume58, Issue21May 20, 2019Pages 6810-6811 ReferencesRelatedInformation
