Researchers from ZIOC RAS developed a method for the synthesis of organometallic chalcogenides-based materials of various morphology

3 september 2020 г.

Nanostructured inorganic structures based on transition metal sulfides have made a significant contribution to materials science. Their unique electronic properties and broad possibilities for tuning of the morphology and composition of nanocrystals made it possible to create efficient photo- and electrocatalysts, energy storage devices, sensors, and biological markers, light-emitting devices, as well as high-capacity materials for lithium, sodium and magnesium-ion batteries. The introduction of fragments into transition metal sulfides opened up new horizons for the synthesis of functional materials. Key feature in the structure of polymeric thiolates is a high affinity of sulfur atoms to metal centers and stability of the metal-sulfur core, which makes the synthesis of these compounds easily reproducible. However, as a result of chemical transformations with the participance of coordination thiolate polymers, the destruction of polymer structure often occurs, which makes difficult modification of these materials without changes of micro- and nanoscale properties.

Researchers from ZIOC RAS discovered a new solid-phase reaction of carbon-sulfur bond formation with the use of metal-containing coordination polymers. By changing the substituent in the organic thiolate ligand or choosing a solvent at the initial stage of the synthesis of nickel thiolate coordination polymers, the morphology of the final materials can be tuned, which makes it possible to consider developed method as an efficient approach for creating nanomaterials of organometallic chalcogenides of various new morphologies.
