Research topics


• Molecular engineering – molecular materials and molecular electronics.

• Spin transition molecular materials.

• Dynamics, kinetics, thermodynamics and mechanisms of spin state transitions, metastable spin
state trapping and spin phase transitions.

• Applications of physical methods in structural chemistry of coordination compounds (magnetic susceptibility,
UV–VIS, IR, ESR, NMR, Mössbauer, X-Ray single crystal and powder sample diffraction, specific heat,
applied quantum chemistry).

• ESR spectroscopy of low-symmetry matrix trapped centres.

• Reactivity and spectroelectrochemistry of paramagnetic centres in “unusual” oxidation states.

• Design of novel ligating systems.

• Synthesis and structure of polyheterocyclic systems
