Modulation of Lanthanide Luminescence with the Mechanical Bond: Antenna‐Emitter Confinement in a Compact [2]Rotaxane

Angewandte Chemie, EarlyView.
Luminescent lanthanide emitters typically need sensitization from an attached chromophore – an “antenna” – to have useful emission intensities. Here we show that the mechanical bond can be used to connect the antenna to the emitter, providing unique stimuli‐responsiveness to the resulting assemblies.

Biosynthese des Rotalgen‐Diterpens Peyssonnosol in Bakterien

Angewandte Chemie, EarlyView.
Zwei Terpensynthasen aus Anaerolineae‐Bakterien katalysieren die Biosynthese von Peyssonnosen‐artigen Diterpenen aus Rotalgen. Ortsgerichtete Mutagenese ermöglichte einen partiellen Funktionswechsel, der zur Bildung zusätzlicher Nebenprodukte führte.

A Polyaromatic Metallotube With a Dual Multi‐Functionalization Ability

Angewandte Chemie, EarlyView.
A new polyaromatic metallotube, formed from PtCl2 and bispyridine ligands, undergoes dual multi‐functionalization via substitution on the metal hinges. The first multi‐functionalized Pt(II)‐tube exhibits high water solubility as well as binds one molecule of fullerene C60, which is subsequently released through the second multi‐functionalization, in a ...

An energy transfer kinetic probe for OH-quenchers in the Nd(3+):YPO4 nanocrystals suitable for imaging in the biological tissue transparency window.

Physical Chemistry, Chemical Physics - PCCP, 2014
Tetragonal xenotime-type yttrium orthophosphate (YPO4) Nd(3+) doped nanoparticles suitable for biomedical applications were prepared by microwave-hydrothermal treatment. We applied the energy transfer probing based on the analysis of kinetics of impurity

Nonmonotonic Diameter Dependence of Thermal Conductivity of Extremely Thin Si Nanowires: Competition between Hydrodynamic Phonon Flow and Boundary Scattering.

Nano letters (Print), 2017
By carefully and systematically performing Green-Kubo equilibrium molecular dynamics simulations, we report that the thermal conductivity (κ) of Si nanowires (NWs) does not diverge but converges and increases steeply when NW diameter (D) becomes ...
