Popis: Time-resolved circular dichroism spectra can reveal changes in chirality on ultrashort time scales, but achieving sub-picosecond time resolution is still a challenge. Here the authors demonstrate 100-femtosecond time-resolved CD mapping of polyfluorene copolymer thin films, revealing a supramolecular origin of their chiroptical response.
