Research

Functionalized polymers are prepared by conventional or special methods of organic and polymer chemistry (chemical modification of polymers, ionic or radical polymerizations of special monomers with reactive groups). Polymers with reactive groups serve as precursors for fluorescence labeling. Dynamic and structural properties of macromolecular associations and supramolecular complexes are investigated by time-resolved and steady-state fluorescence techniques (polarized fluorescence, nonradiative energy transfer).

At present, the research activities are focused mainly on two areas:

• Polymer ligands as energy donors for lanthanides (Tb³⁺, Eu³⁺). Transitions between f orbitals are strictly parity forbidden, which implies low luminescence quantum yields of lanthanides. We are looking for convenient polymer and supramacromolecular ligands with fluorophores as energy donors for lanthanides.
• Organic electroluminescence: synthesis of special high-molecular-weight materials for organic light-emitting devices (LED) with excellent optoelectric properties (hole- or electron-transporting polymers, polymer emitters with high electroluminescence quantum yields, etc.).
