Chiral induction and chiral detection using thermotropic and lyotropic liquid crystalline soft matter. Polarity and chirality, including ferroelectric and antiferroelectric smectic liquid crystals. Photophysical and eletrooptic effects. Ferroelectric liquid crystals on graphene. Liquid crystals from nano DNA.
Polarized optical microscopy, UV-photopolymerization, liquid crystals electrooptics equipment, dielectric spectroscopy, clean-room fabrication of liquid crystal devices, UVvis spectroscopy, light scattering and X-ray diffraction facilities at research partners.
Focus of future research:
- Studies of ferroelectric and antiferroelectric liquid crystals acting as switchable, polar overlayers on graphene.
- Graphene as combined transparent electrode and planar ordering surface layer.
- Chiral induction and detection
- nano DNA on graphene
