The expertise is in the domains of Theoretical / Computational Chemistry & Chemical Physics,
with a particular focus on interdisciplinary Nanoscience (studies of nanometer-sized systems).
The objects of interest are generally specified as polyatomic systems (atomic and molecular
complexes and clusters, atoms and molecule on surfaces, interfaces at molecular level).
Present directions of research focus on core-shell cluster nano-systems with molecular species inside
metal-atom cages (interacting non- and covalently), and on intermolecular junctions mediated by
ion-pair links or metal atoms. Other interests include multi-electronic-state model potentials,
determination and efficient representation of multi-dimensional intermolecular potential surfaces.
The main aims are to predict new stable structures and compositions, to investigate relationships
between various properties, and ultimately to design systems with desirable characteristics.
Potential practical applications include development of new materials with unique
properties, novel catalytic agents, elements of molecular electronics and machinery, molecular
storage and delivery, energy storage at molecular level.
(1) Clusters - doped and mixed metal-based systems
A new family of molecule-doped metal clusters is investigated (unlike previously studied atom-doped systems),
allowing new dimensions in structure and property design and enabling creation of unique core-shell species (filled cages);
current focus is on carbon-, hydrogen- and hydrocarbon-doped metal species.
(2) Charge-transfer intermolecular insertion complexes
Novel types of complexes are discovered, with molecules trapped between atomic/molecular ion-pairs,
exhibiting unusual bond patterns and unique characteristics such as hyper-valence of 2nd-row elements (carbon) and huge dipole moments,
allowing energy storage in metastable states and use of molecules in a strong electric field;
current focus is on compounds of main group metals with halo-hydrocarbons.
(3) Metal-organic molecular interfaces
Increased stabilization and charge/excitation-induced geometry variation in sandwich complexes of metal atoms with unsaturated molecules is explored,
enabling construction of highly stable metal-mediated junctions and 1D polymeric chains to 3D frameworks with novel properties,
and offering new options for molecular structure alterations;
current focus is on main group metal atoms with hydrocarbons.
