Abstract
Tellurium is now recognized as a ‘technology-critical element’ that is quickly being
used in innovative applications. The chemistry of organotellurium ligands has improved
rapidly during the last three decades. Because of their enhanced accessibility and
the possibility that they would display significantly different properties than their
sulfur counterparts, these ligands of heavier chalcogens have sparked considerable
attention. The next sections will go through the various tellurium ligands and associated
transition-metal complexes. Organochalcogen ligands are exceedingly flexible ligands
that may react with nearly any transition metal to form a wide range of compounds,
including multidentate ligands.Tellurides of various metals have lately been investigated
for potential use in storage devices, solar cells, piezoelectric, medical applications,
electronics, photothermal treatment, nanoplatelets, nanocrystals, catalysis, and other
fields. Researchers are interested in metal chalcogenide heterostructures because
of their improved charge transport and synergistic optoelectronic and catalytic properties.
A sensor for various metals based on Te electrodes and a donor ligand are used to
generate electrical signals and identify different metals. Due to the scarcity of
tellurium, metal telluride nanocrystal heterostructures have received less attention
than metal sulfide and metal selenide nanocrystal heterostructures.
