Current Research
Rajca group’s research interest is in the area of organic and biomaterials chemistry. The underlying theme of our research is rational design and synthesis of new materials (molecules and polymers) with magnetic and optical properties. Rational design of new structures and materials (molecules and polymers) with targeted properties are implemented using the tools of organic synthesis, crystallography, magnetic resonance spectroscopy (NMR and EPR) and imaging (MRI), as well as magnetometry (SQUID), circular dichroism (CD) spectroscopy and multiangle light scattering (MALS).

The specific ongoing research projects are high-spin organic molecules and polymers as building blocks for organic magnets, organic radicals as contrast agents for biomedical imaging, and chiral π-conjugated molecules.
