Tailoring Liquid Crystalline Self‐Assembly and Photophysical Properties of Unsymmetrical Fluorenones via Polar Terminal Groups

open access: yesChemistry – A European Journal, EarlyView.
Novel liquid crystalline fluorenones bearing various head groups were synthesized and characterized. By alteration of the head group, N, SmC, or SmA phases were obtained, and emission properties could be tuned depending on solvent or temperature. ABSTRACT In this work, a series of novel unsymmetrical fluorenone derivatives bearing various head groups ...

Photochemical and Thermal Activation of a Diarylbismuth Azide

open access: yesChemistry – A European Journal, EarlyView.
We report the synthesis and characterization of a novel diarylbismuth azide and its divergent reactivity upon thermal or photochemical activation. These findings contribute expanding the reactivity landscape of heavy pnictogen compounds and sets the basis for further investigations. ABSTRACT Azides are widely employed in synthesis as convenient nitrene

A Homoleptic Copper(I) Acetylene Complex

open access: yesChemistry – A European Journal, EarlyView.
Ligand substitution of weakly coordinated N2 in [(N2)Cu{Al(ORF)4}] (RF = C(CF3)3) leads to the homoleptic acetylene complex [Cu(C2H2)3]+[Al(ORF)4]−, which was characterized by single crystal x‐ray diffraction, NMR, and Raman spectroscopy, as well as by extensive quantum chemical calculations. ABSTRACT We report the synthesis and characterization of the

Molekulare Solarthermiespeicher—zwei Fallstudien zur Optimierung Molecular solar thermal storage—two case studies on optimization

open access: yesChemie Ingenieur Technik, EarlyView.
Molekulare Solarthermiespeicher (MOST) überführen Licht in Wärmeenergie, die zu einem späteren Zeitpunkt genutzt werden kann. Die Optimierung solcher Systeme wird von vielen Parametern bestimmt, wie hier an zwei Beispielmolekülklassen, Azobenzole und Azaborinine, gezeigt.

Thermal Degradation of PFAS in Different Scales: Measurement of Hydrogen Fluoride (HF)

open access: yesChemie Ingenieur Technik, EarlyView.
The communication article is about the challenges to balance a combustor in the case of fluorine when incinerating PFAS containing materials. Several analytical methods are compared: for continuous measurement, FTIR with TDLS. The detected fluorine species are further compared with results upon IC and pyrohydrolysis for discontinuous measurements in ...
