Solvent-Triggered Long-Range Proton Transport in 7-Hydroxyquinoline Using a Sulfonamide Transporter Group

The ability of long-range proton transport by substitution of 7-hydroxyquinoline at the eighth position with sulfonamide and sulfonylhydrazone rotor units to act as a crane-arm has been studied. Different proton transport pathways triggered by different stimuli have been established depending on the structure of the crane-arms. Solvent-driven proton switching from OH to the quinoline nitrogen […]

Benzothiazol picolin/isonicotinamides molecular switches: Expectations and reality

The ground state tautomerism and excited state intramolecular proton transfer in two new molecular switches, namely N-(benzo[d]thiazol-2-yl)picolinamide and N-(benzo[d]thiazol-2-yl)isonicotinamide, are studied in acetonitrile by the combined use of steady state and time dependent spectroscopy and DFT calculations. Although, according to the theoretical calculations, two potential switching pathways are possible in N-(benzo[d]thiazol-2-yl)picolinamide, either through the pyridine […]

Union of Scientists in Bulgaria Grand Prize for PhD thesis awarded to Dr Silvia Hristova

We are proud to announce that Dr Silvia Hristova, who defended her PhD thesis in our group last year, was awarded by The Union of Scientists in Bulgaria for best PhD thesis in 2020. The thesis of Silvia considers the possibility of using controlled proton transfer as an elementary process in the molecular machinery. The […]
