Boron Monofluoride Complexes Bearing π‐Expanded Coumarin Subunits: Facile Synthesis, Crystal Structure, and Solid‐State Enhanced Emission

open access: yesChemistry – A European Journal, EarlyView.
We here report the design, facile synthesis, experimental, and theoretical characterization of a novel class of monofluoroborate compounds featuring π‐expanded coumarin subunits displaying solid‐state enhanced Emission. The origin of this phenomenon is disclosed by combined theoretical and spectroscopic investigations.

Torsion vibration damper

The Journal of the Acoustical Society of America, 1983
A torsional vibration damper having limit stops to limit the compression of the springs and to avoid overstraining of the springs. Spring retainers which seat on the driving and driven members have protrusions and recesses to minimize relative rubbing motion and wear and provide improved alignment of the spring seats in the assembly with the springs ...
