TSU scientist Rashid Valiev and colleagues from the universities of Helsinki and Oslo have discovered a new type of rare molecules whose properties can be controlled by changing the induction of an external magnetic field.
These are paramagnetic molecules from the class porphyrins.
Porphyrins are part of hemoglobin and chlorophyll and are closely related to the processes of photosynthesis and respiration in living organisms.
The results of the study were published in the journal Chemical Communications of the Royal British Chemical Society.
Open paramagnetic porphyrins with a closed electron shell are very rare molecules, because they have a specific electronic structure.
Usually, molecules with such a structure are very unstable, and open porphyrins, on the contrary, are unchanged even in the air around us.
