Circularly polarized luminescence of biaryl atropisomers: subtle but significant structural dependency
Abstract
The signs of circularly polarised luminescence and circular dichroism of chiral biaryl fluorophores in the CHCl3-dissolved state (solution state) and the PMMA-film-dispersed state (solid state) were successfully controlled by modifying the internal axial chirality and the axial bonding position of the biaryl units.
