Journal ArticleDOI
Referenced dual pressure- and temperature-sensitive paint for digital color camera read out.
Lorenz H. Fischer,Cüneyt Karakus,Robert J. Meier,Nikolaus Risch,Otto S. Wolfbeis,Elisabeth Holder,Michael Schäferling +6 more
TL;DR: The first fluorescent material for the referenced simultaneous RGB (red green blue) imaging of barometric pressure and temperature is presented, which allows for the simultaneous imaging of both indicator signals, as well as the reference signal, in one RGB color picture without having to separate the signals with additional optical filters.
Journal ArticleDOI
Oxygen and temperature sensitivity of blue to green to yellow light-emitting Pt(II) complexes
Cüneyt Karakus,Lorenz H. Fischer,Sebastian Schmeding,Johanna Hummel,Nikolaus Risch,Michael Schäferling,Elisabeth Holder +6 more
TL;DR: The synthesis and photophysical properties of a series of yellow-green to blue-green emitting heteroleptic, cyclometalated Pt(II)(acac) complexes based on substituted phenylpyridine and tetrahydroquinoline ligands are reported, which are promising candidates as inert reference dyes in optical sensors.
Journal ArticleDOI
Photophysical properties and OLED performance of light-emitting platinum(II) complexes.
Dimitrios Kourkoulos,Cüneyt Karakus,Dirk Hertel,Ronald Alle,Sebastian Schmeding,Johanna Hummel,Nikolaus Risch,Elisabeth Holder,Klaus Meerholz +8 more
TL;DR: Depending on both the structure of the C^N cyclometalating ligands and the dopant concentration in the matrix, these platinum(II) complexes exhibit different aggregation tendencies, which affects the photoluminescence spectra of the investigated compounds and colour-stability of the fabricated OLEDs.
Journal ArticleDOI
New Heck-Type Coupling Reactions of Natural Tetrapyrroles − Synthesis of Porphyrinoligomers Bridged by Divinyl- and Trivinylbenzene
Rainer Gauler,Nikolaus Risch +1 more
TL;DR: Using palladium(0)-catalyzed coupling reactions, this paper were able to synthesize mono-, di-, and trimeric porphyrins linked by di- and trivinylbenzenes.
Journal ArticleDOI
Unusual Terpyridines as Ligands for Novel Light-Emitting Iridium(iii) Complexes: Synthesis and Characterization
Andreas Winter,Christoph Ulbricht,Elisabeth Holder,Elisabeth Holder,Nikolaus Risch,Ulrich S. Schubert +5 more
TL;DR: Based on S-shaped terpyridines, a series of yellow, orange, and red-orange light-emitting iridium(iii) complexes has been synthesized.
