Practical and Efficient Large-Scale Preparation of Dimethyldioxirane
Hannes Mikula,Dennis Svatunek,Daniel Lumpi,Florian Glöcklhofer,Christian Hametner,Johannes Fröhlich +5 more
TL;DR: An improved procedure for large-scale and also commercially viable preparation of dimethyldioxirane (DMDO), a common and widely used oxidation agent in organic synthesis, was developed using a conventional laboratory plant as mentioned in this paper.

Oxadiazole based bipolar host materials employing planarized triarylamine donors for RGB PHOLEDs with low efficiency roll-off
Paul Kautny,Daniel Lumpi,Yanping Wang,Antoine Tissot,Johannes Bintinger,Ernst Horkel,Berthold Stöger,Christian Hametner,Hans-Rudolf Hagemann,Dongge Ma,Johannes Fröhlich +10 more
TL;DR: In this paper, the impact of incorporating planarized electron-donating triarylamine (TAA) structures on intramolecular charge transfer was examined, and the results correlate with an increasing ortholinkage effect and decreasing donor strength of the TAA moiety by planarization.
Systematic Investigations on 1,2,3-Triazole-Based Compounds Capable of Second Harmonic Generation
Daniel Lumpi,Florian Glöcklhofer,Brigitte Holzer,Berthold Stöger,Christian Hametner,Georg A. Reider,Johannes Fröhlich +6 more
TL;DR: In this article, 1,2,3-Triazole-functionalized ene-yne compounds, synthesized by thiophene (selenophene) ring fragmentation followed by azide-alkyne cycloaddition, were investigated as a basis for nonlinear optical...
Charge-transfer states in triazole linked donor-acceptor materials: strong effects of chemical modification and solvation.
Paul Kautny,Florian Glöcklhofer,Thomas Kader,Jan-Michael Mewes,Berthold Stöger,Johannes Fröhlich,Daniel Lumpi,Felix Plasser +7 more
TL;DR: It is shown that enhanced charge separation, as induced by chemical modification or solvation, reduces the singlet-triplet gaps and that two of the investigated molecules possess sufficiently low gaps to be considered as candidates for thermally activated delayed fluorescence.
Synthesis, spectroscopy, and computational analysis of photoluminescent bis(aminophenyl)-substituted thiophene derivatives.
TL;DR: A robust procedure for the prediction of the fluorescence spectra of oligothiophene derivatives is presented and a semiclassical approach for describing the vibrational broadening of the spectra is employed.
