An Updated Perspective of Nano Schiff Base Complexes: Synthesis, Catalytic, Electrochemical, Optical, Crystalline Features and Pharmacological Activities

Schiff bases are chemical compounds obtained via the conjugation reaction of ketones or aldehydes with amines. Schiff bases and its compounds are widely used in industries and also have significant pharmacological efficiencies including antitumor, antiviral, antibacterial, antifungal, anti-cancer and DNA binding. The most of these compounds exhibit outstanding catalytic activities. Nano-Schiff bases are deemed to be the most multitasking ligands as they form complexes with the metal atoms. They are called facilitating ligands because these compounds can be prepared easily by condensation. The complexes of transition metals are the essential metal complexes of these compounds. Nano-Schiff bases and its metal complexes are highly helpful in scavenging the free radicals and thus to balance living bodies from the hostile impacts of these radicals. It overcomes an independent sphere of research in chemistry due to the recent amazed research on Schiff bases. Although these compounds are widely experimented, the pharmacological activities with catalytic, electrochemical, optical and crystalline properties of these compounds have to need vigorous investigation. However, we demonstrate various synthesis mechanisms of nano-Schiff bases and the essential activities of metal complexes. The present systematic overview will intend to make a profile of catalytic, electrochemical, optical, crystalline properties and pharmacological activities of metal complexes containing nano Schiff bases.
