Research
Structure and dynamics of macromolecular and model systems are
studied on various levels starting from the atomic level (0.1 nm)
up to that of supramacromolecular systems, polymer crystallites
and microdomains in polymer blends (100 nm). The leading theme of
research is mobility and order in
synthetic, natural and hybrid macromolecular systems with the
ultimate goal to find and explore structural factors of
spontaneous self-ordering of macromolecular systems as well as
conditions at which local and semilocal mobility cease to compete
with the order and start to cooperate in a dynamic functional
order. As a special topic in this filed, cooperative
effects in the supramolecular organization of macromolecules
are intensively studied.
Some of the objects of research are: supramacromolecular
systems, in particular macromolecular micelles and similar
objects, macromolecular complexes (e.g., of stereoregular
polymers with other polymers or low-molecular-weight compounds,
polyphosphates and nucleic acids with polycations and their block
copolymers, HIV protease with protein inhibitors),
thermoreversible gels, partially ordered polymer structures,
polymer crystallites, polymer blends and hybrid polysiloxane
networks. The main methods used are:
- molecular spectroscopy: multinuclear, multiquantum 1D and
2D high-resolution and solid state NMR, FTIR and Raman
spectroscopy (including confocal micro-Raman, by
collaboration)
- static and time-resolved WAXS, SAXS and SANS
- X-ray diffraction
- quantum mechanics and molecular dynamics (model
calculations and modelling-assisted structure analysis)
