Ural Scientists Create a Molecular Nano-Building Kit
Дата публикации: 16-08-2026 19:00:00
Associate Professor of the SUSU Department of Theoretical and Applied Chemistry Anastasiia Rybakova, jointly with her colleagues from Ural Federal University named after the First President of Russia B.N. Yeltsin and Ural Division of the Russian Academy of Sciences, have taken part in a project on studying the molecular structure of a very promising nitrogen-containing organic compound.
To be exact, the scientists have studied the structure of 1,1′-(2,6-Pyridinediyl)bis[6,7-dihydro-4-(4-methoxyphenyl)-5H-cyclopenta[c]pyridine. This molecule belongs to the class of terpyridines that are the key "building blocks" in materials science and coordination chemistry.
One cannot really call such molecules "bricks". Those look more like a bird or a building structure. The pyridine ring here acts as the beam or the body in the centre, while the two wings are formed by other complex-compound rings.
Earlier this compound was obtained by boiling the mixture in a toxic organic solvent (1,4-Dioxane) for 6 hours. Now, the team of researchers has proposed to use a more environment-friendly method of PASE (Pot, Atom, and Step Economy), so they would not need the toxic solvent. The time of reaction is reduced down to 3 hours, and the product output equals 52%, what is much better as compared to the previous technology.
Having examined the result using РСА X-ray diffraction analysis, the scientists have found that the molecules form dimers – pairs where these are positioned "head-to-head".
Why is this discovery important? Modern nanotechnologies allow to create functional materials targeted for certain tasks.
So, both terpyridines and their metal-based compounds look as promising building blocks for the creation of organic light-emitting diodes, materials for organic solar cell batteries, and thin-film transistors thanks to their capacity for effective luminescent glow and charge transfer.
The capacity to bind to metal ions while changing the optical properties makes such "blocks" a potential resource for the creation of high-sensitivity optical-and-chemical sensors.
Finally, in the future, those could help create biomarkers to be used in oncology medicine.
This work has been carried out as part of the Russian Science Foundation project No.25-73-30016 and published in the Chemistry series of the Bulletin of the South Ural State University.
