Triggering Dissymmetry in Achiral Dye Molecules by Chiral Solvents:\ud Circular Dichroism Experiments and DFT Calculations

摘要

The electronic circular dichroism spectra of achiral product ‘‘Lumogen F Red’’\ud(ROT-300) in four different chiral solvents are recorded at different temperatures. DFT calculations\udallow to identify two enantiomeric conformers for ROT-300. In vacuo they are equally\udpopulated; in chiral solvents one enantiomer prevails. Thermodynamic quantities involved in\udthe chiral preference are derived.
