Molecular Crystals Laboratory is engaged in the complex study of new synthetic metals, organic superconductors, low-dimensional conducting systems, fullerenes, their complexes and other derivatives. The speciality of the laboratory is the use of infrared microreflection spectroscopy of polarized light, at temperatures between 5K and 300K, to study molecular conductors. Other experimental techniques in use: reflection and absorption UV-VIS-NIR-IR spectroscopy, IR spectroscopy of submilimeter crystals, electrical conductivity and thermoelectric power measurements. Theoretical studies of disordered systems of mesoscopic size; conductance in magnetic field, conductance fluctuations and electron localization.

Main problems under investigation:

  • spectral studies of conducting ion-radical salts, charge transfer complexes and various derivatives of fullerenes
  • experimental and theoretical studies of electron - molecular vibration couplings
  • theoretical study of electronic transport in disordered and mesoscopic systems
  • study of correlated electron models, their ground state and phase transitions
  • phase transitions in low- dimensional crystals and fullerene complexes
  • characterization and investigation of physical properties of low-dimensional organic conductors and fullerene complexes
  • specific interactions in low-dimensional molecular solids
  • preparation of selected ion-radical salts, charge transfer complexes in particular based on C60
