DESCRIPTION OF THE GROUP
This group specializes in organic synthesis, applied in two main fields: supramolecular chemistry and construction of metal-organic frameworks (MOFs), which are defined as crystals containing voids of nanoscopic size (cavities, channels etc.).Supramolecular chemistry or “above the molecule” chemistry is an interdisciplinary branch of studies, at the interface of chemistry, biology and physics. It tackles phenomena, in which intermolecular forces are crucial. Hence, supramolecular chemistry lies behind both biology and nanotechnology.
Metal-organic frameworks (MOFs) are crystal, porous, 3 dimensional coordination polymers, in which inorganic building units are bound by organic linkers. Thanks to the proper selection of organic ligands and metal centers, MOFs can be used for gas storage, especially hydrogen and methane, as drug carriers, in ion exchange, in sensor technology, in non-linear optics, as magnetic and luminescent materials and in many more branches of science and technology. Moreover, MOFs provide unique microhabitat for catalysis, which resemble enzyme interior.

Supramolecular interests of the group include mostly supramolecular chemistry of anions: synthesis and research on receptors, sensors and anion transporters, application of anions as templates for production of i.a. rotaxanes and catenanes.Furthermore, the group works on molecular photoswitches, especially photoswitchable receptors and catalysts, conductive polymers and self-organization of multivalent structures.
In the framework of the Ministry of Science and Higher Education project IDEA PLUS, the group develops new methods of grafting homogenous catalysts into MOFs and studies catalytic properties of obtained materials.The aim of these activities is to prove that the presence of homogenous catalysts inside MOFs can facilitate preparing new catalytic systems for tandem reactions through limitation of mutual deactivation of catalysts.
There is an excellently equipped laboratory at the disposal of this group, dedicated to organic synthesis (i.a. fume hoods with vacuum/argon lines and small equipment necessary for organic synthesis) and to synthesis of MOFs (i.a. autoclaves, programmable heaters, drier for activation of porous materials with supercritical CO2, vacuum drier with a pump), spectrofluorometer, UV-vis, GC, HPLC, microwave reactor, ball mill, Parr hydrogenator and many other instruments.
Group members are open to scientific cooperation and joint research and implementation projects, considering metal-organic frameworks or supramolecular chemistry.
