The studies performed in the Laboratory of Crystal Engineering focus on the solid state and the rational modification thereof. They oscillate on the border of a few divisions of chemistry such as organic, coordination and supramolecular chemistry, material science and crystallography. They aim to expand the knowledge concerning the design of crystals of particular composition and properties.
Therefore, in the Laboratory, we conduct systematic studies on the effect of different factors on the crystallisation products, we attempt to gain insight into the phenomena of polymorphism, supramolecular isomerism, and host-guests systems’ chemistry. Furthermore, by using sophisticated software, we analyse the intermolecular interactions that stabilise the crystal structures. We are also interested in the design of new functional materials, especially those exhibiting porosity, with emphasis on their sorption ability and selectivity. The associated synthetic work embraces the preparation of organic, organometallic and coordination compounds with porous structures. Studying their sorption properties allows us to further optimize them by structural modifications, including changes in the size and shape of the pores and their functionalization. Simultaneously, we are going on with studies on the use of porous crystals as reaction vessels, on dynamics in the crystals caused by external factors (so called single-crystal-to-single-crystal transformations) and the possibilities to utilise selected crystals of this type in sensor devices.
The facilities available allow us to perform structural studies using a range of methods, most notably single-crystal X-Ray diffraction (SCXRD), X-Ray powder diffraction (XRPD), spectroscopic studies (UV-Vis, IR, NMR) and thermal analyses (TGA, DTA, DSC).
