Abstract:
The invention relates to novel fluorene derivatives, which are especially suitable for use in birefringent films with negative optical dispersion, to novel liquid crystal (LC) formulations and polymer films comprising them, and to the use of the fluorene derivatives, formulations and films in optical, electrooptical, electronic, semiconducting or luminescent components or devices.
