Seminar “Metallophilic interactions in a family of CuI-based 1D polymers showing colorful short-lived thermally activated delayed fluorescence and phosphorescence induced by photo- and X-ray irradiati”
Exploiting 2-(alkylsulfonyl)pyridines as 1,3-N,S-ligands, 1D CuI-based coordination polymers bearing unprecedented (CuI)n chains and possessing remarkable photophysical properties were constructed. Metallophilic interactions Cu⋯Cu in these compounds were studied theoretically by DFT calculations and topological analysis of electron density distribution. At room temperature, these coordination polymers show efficient thermally activated delayed fluorescence,
phosphorescence or dual emission in the deep-blue to red range with outstandingly short decay times of 0.4–2.0 μs and good quantum performance. Moreover, the designed compounds emit strong X-ray radioluminescence with the quantum efficiency of up to an impressive 55% relative to well known all-inorganic bismuth germanate (BGO) scintillators. The presented findings push the boundaries in designing thermally activated delayed fluorescence and triplet emitters with
very short decay times.
Seminar “(Pre)association as a crucial step for computational prediction and analysis of the catalytic activity of σ-hole donating organocatalysts”
Based upon the experimentally obtained kinetic data on iodonium salt catalyzed nucleophilic addition of isocyanide to imine leading to imidazopyridine species, a reliable model for DFT calculations has been suggested. It was shown that preassociation of the catalysts with the reaction species might significantly affect the total energy profile of the reaction obtained by DFT.
