Research interests

My research obeys spectroscopy methods such as UV/Vis, Circular Dichroism (CD) and Magnetic Circular Dichroism (MCD). My present studies are focused on interactions between noble metal nanoparticles and chromophoric systems such as porphyrins and porphycenes. I am also interested in the electronic structure as well as redox processes occurring within mentioned chromophores. The main tool I am using in my research is MCD technique.




MCD basics:

-          the presence of  magnetic field causes the different absorption of RCP and LCP, what introduces the chirality into the achiral compound; therefore the investigated molecule doesn’t need to be chiral,

-          MCD spectrum is richer compare to ordinary absorption curve, but still it is a superposition of all contributions,

-          MCD signal is proportional to the strength of magnetic field,

-          only that component of magnetic field, which is parallel to the light propagation direction contributes to the MCD effect,

-          observed MCD spectrum is Δε/ε ratio.



MCD vs absorption



My expertise obeys not only mentioned techniques. During my postdoc I worked on development of flow-aligned polarised Raman (FAPR) of biomacromolecular entities. My goal was to develop a new form of spectroscopy: FAPR that will greatly enhance our ability to obtain structural information on a range of molecules including DNA and membrane proteins. Most of the work was focused on small molecules (steroids, nucleotides and riboflavin derivatives) aligned in PE films. A universal Couette flow cell has been designed and the first experiments with liquid samples have been performed. Finally the new method was called Raman linear difference spectroscopy (RLD). [Anal. Chem. 2012, 84 (3), 1394–1401]

My PhD was concerned with an application of circular dichroism (CD) spectroscopy to structural studies of bicyclic β-lactam carba- and oxaderivatives to establish the scope and limitation of a newly introduced helicity rule. The project included CD, conformational analysis (CaChe software), TD DFT (time-dependent density functional theory) modelling of theoretical curves (Gaussian 03W). Despite its spectroscopic aspects, my PhD predominantly was built around synthetic chemistry using radical methods and metathesis reaction for synthesis of bicyclic β-lactam antibiotics.[Chemistry – A European Journal 2007, 13 (23), 6732-6744]
