Description and Uses

1,2,4-triazole and its derivatives are important structural moieties of many pharmaceutical drugs. Triazoles can also act as ligands to form coordination complexes with transition metal ions. Due to their electron-deficient nature, they exhibit excellent electron-transport and hole-blocking properties, making them promising organic materials in material science applications.
