The electronic circular dichroism spectra of achiral product ‘‘Lumogen F Red’’ (ROT-300) in four different chiral solvents are recorded at different temperatures. DFT calculations allow to identify two enantiomeric conformers for ROT-300. In vacuo they are equally populated; in chiral solvents one enantiomer prevails.

Abstract
The electronic circular dichroism spectra of achiral product ‘‘Lumogen F Red’’ (ROT-300) in four different chiral solvents are recorded at different temperatures. DFT calculations allow to identify two enantiomeric conformers for ROT-300. In vacuo they are equally populated; in chiral solvents one enantiomer prevails. Thermodynamic quantities involved in the chiral preference are derived.File in questo prodotto:
