We target both man-made and naturally occurring bioactive molecules that feature underexplored pharmacophores and/or structural complexity challenging the current state-of-the-art in organic synthesis. Our target compounds are profiled in close collaboration with top-class Czech and international biologists. Research areas of interest include small-molecule modulation of selected human kinases, adenylyl cyclases, and nucleases.

Supramolecular Chemistry Group
prof. Ing. Vladimír Šindelář, Ph.D.

The research group develops new supramolecular hosts that are able to include small molecules and ions inside their cavity. We are particularly interested in two families of compounds: cucurbiturils and bambusurils. These macrocycles are constructed from the same building block, glycoluril, but have very different binding abilities. We have contributed to the research of cucurbiturils in terms of modification and also the preparation of molecular switches based on these macrocycles. The first bambusurils were synthesized in our research group in 2010. We later recognized that bambusurils are potent receptors for various inorganic anions in both aqueous media and organic solvents. We are currently investigating the potential of bambusurils for anion sensing and transport.

Research topics include elemental imaging of biological tissues to monitor the effect of anticancer drugs (LA-ICP-MS), studying the use of metal nanoparticles for immunoassays (LA-ICP-MS), imaging the distribution of elements and isotopes in rocks and minerals for the study of geochemical processes (LA-ICP-MS, LIBS), development of software tools for spectral data processing and image generation, research and development of new methods for direct analysis of solid samples of geological materials and advanced technological materials (ED-XRF, LIBS, LA-ICP-MS). Research is also focused on sample digestion and conversion to the solution using advanced technologies (microwave digestion, induction melting) for ICP-OES, ICP-MS and AAS analysis and for sample preparation for solid state analysis (LA-ICP-MS, LIBS, ED-XRF). The basic research is focused on the study of the influence of laser ablation parameters on the aerosol particle distribution and vaporization in the plasma with implications for element and isotope fractionation, as well as on the study of ablated surface properties including roughness and nanoparticle coverage on aerosol distribution and analytical signal.

Challenges that are of more theoretical interest include modelling at low temperatures or the design and optimization of appropriate models that fully capture the physical nature and behaviour of the phases.

Inorganic and material chemistry

Laboratory for Research on the Structure and Properties of Metallic Systems
prof. RNDr. Mojmír Šob, DrSc.

One of the pillars of scientific activities of our group is the theoretical research of electronic structure and of mechanical as well as magnetic properties of materials containing extended defects (grain boundaries, antiphase and interphase boundaries). We study also the surface effects and properties of surfaces. Here we employ the basic equations of quantum mechanics. This enables us to gain a deeper understanding of internal constitution of materials and relations between their structure and technologically important properties.

An important part of the group is constituted by the Laboratory of Thermal Analysis and Mass Spectrometry. It deals with the study of thermal effects, in particular of phase transformations, thermodynamic properties, thermodynamic and surface processes, and reaction kinetics by means of differential scanning calorimetry (DSC), differential thermal analysis (DTA) and Knudsen effusion mass spectrometry (KEMS). The research is focused mainly on the study of thermoelectric materials, nanostructured and nano materials, and related systems.

Another area of the activity of the research group is represented by the theoretical and experimental study of nanoparticles of metals and their alloys. In the theoretical field, we are concerned with the prediction of phase diagrams of nanoalloys and, in particular, with their verification. The focus of the experimental area is the synthesis and characterization of nanoparticles.

Laboratory of synthesis of metal complexes and coordination polymers
prof. RNDr. Jiří Pinkas, Ph.D.

Research is directed towards the synthesis of new polytopic ligands and their utilization in the construction of polynuclear transition metal and lanthanide phosphonate complexes and functional coordination polymers with interesting properties (magnetic, porous, luminescent). The new derivatized phosphonate ligands are then used in the preparation of the metalophosphonate-based molecular building blocks. The synthesis provides homo- and heterometallic phosphonate complexes with polynuclear cores, such as {Co7}, {Co12}, {Ni8}, {CoxDy}, x = 6,7,9, {Co2Ln4}, {LnZn9}, {LnZn9}, Ln = Gd, Tb, Dy. Molecular products are characterized by single-crystal X-ray diffraction on a Rigaku diffraction system. Infrared (IR) spectroscopy is performed on a Bruker Tensor T27 with an ATR module. Raman spectra are measured on a Horiba Scientific LabRam HR Evolution spectrometer with the Olympus microscope. Thermal analyses (TG/DSC) is carried out on a Netzsch STA 449C Jupiter instrument coupled to an IR spectrometer. GC/MS measurements are made on a Chromatograph Thermo Scientific Trace GC Ultra coupled with a mass spectrometer TSQ Quantum XLS. Solution NMR spectra are measured on a Bruker Avance IIITM 500 MHz spectrometer with a 5 mm BBFO probe.

Attention is also given to robust architectures of MOFs, which can be exploited as matrices for the crystallization of small molecules (crystalline sponges). Another line of research includes the search for a functional connection between metal complexes and organic macrocycles and molecular clips. Using a rotating anode dual-wavelength X-ray diffractometer, we are able to determine structures even of very tiny crystals and of very complex systems with large unit cells.

Thanks to the thorough characterization and thus detailed knowledge of the newly synthesized materials, the correlations between the synthesis procedures of the samples and their catalytic properties is studied. At present, the group focuses on the conversion of ethanol (to ethylene, acetaldehyde, or butadiene), reactions of epoxides (e.g. with CO2, amines and alcohols) and related reactions (e.g. MPV reduction of cyclohexanone).
