Chiral, Magnetic, and Photosensitive Liquid Crystalline Nanocomposites

Chiral, Magnetic, and Photosensitive Liquid Crystalline Nanocomposites

Structure of nanocomposite of liquid crystals

We explored magnetic and structural properties of multifunctional chiral nanocomposites based on magnetic nanoparticles and achiral liquid crystals. Our magnetoresponsive nanoparticles provided a stable nanocomposite when dispersed in achiral liquid crystals, giving rise to chiral supramolecular structures that can respond to UV-light illumination, as invented by prof. Kohout and his team. The surface modification of the nanomagnets by the achiral liquid crystals introduces significant enancement of their magnetic response.
