Research themes

The WHAM group deals with the construction and getting knowledge on multicomponent molecular systems, what is an extremely interesting instrument in development of strategies for obtaining new molecular architectures of functional nature based on magnetic, optical, chiral or sorption properties, including also structure-properties-function schemes tunable owing to phase transitions and reconstruction of the crystal lattice. We are interested (i) in discovering completely new architectures, obtained as a result of self-assembly processes involving selected molecules or their aggregates, as well as (ii) in deliberate construction based on already known architectures through interchanging of components dedicated to specific places or entire areas of the crystal lattice, without its significant disturbation, or at least with preservation and reproducibility of local molecular arrangement. Thus, using principles of the building block approach and molecular tectonics, and based on hierarchical nature of molecular networks, we aim at obtaintion of new materials of significantly modified electronic valence structure and physicochemical properties and / or reactivity in a controlled manner. According to the above, we prepare and examine:


  • molecular solid solutions of isotropic nature, properties of which change continuously with the change of the content of essential components;
  • domain-type molecular crystal composites, with various properties coexisting in different areas of a single object;
  • polynuclear coordination clusters showing speciation in the nature of coordination sites and individual behavior of the relevant complex moieties;
  • co-crystalline phases (co-crystals, co-crystalline salts) including simple and polynuclear coordination complexes.
  • multisite anion receptors dedicated to the binding and recognition of d-block metal ion complexes as important building blocks in the construction of polynuclear complexes.

The scientific and philosophical nature of the above research themes was shaped on the basis of the previous experience of the group director and his project team, with particular emphasis on the modular synthesis of molecular connections showing:

  • reversible spin and structural phase transformations (spin-crossover, electron transfer);
  • chirality and non-centrosymmetry;
  • magnetocaloric effect;
  • structural disorder;
  • new patterns of non-covalent interactions, e.g. charge transfer anion-π interactions.
