Importance of Schiff base Complexes with transition metals : A Review

Schiff’s bases are commonly used for industrial purpose and also exhibit a wide range of biological activities. These are the most widely used organic compounds which are used as intermediates in organic synthesis, catalysts, pigments and dyes, polymer stabilizers, etc. Complexes of Schiff base with transition metals, the largest group of elements on the periodic table, have been used as medicine, pharmacy, coordination chemistry, biological activities, food packages, dyes and polymer and also used as an O2 dectector. Recent studied about Schiff bases and their metal complexes show numerous applications in pharmacology such as antiviral, antifungal, antimicrobial, antimalarial, antituberculosis, anticancer, anti- HIV, catalytic application in oxidation of organic compounds and nanotechnology. Due to the interaction of metal chelates with the DNA helix, they can be used in the design of new design of new models in diagnosis and therapy. Due to their photochromism feature, they can be used in different fields, such as controlling and measuring radiation intensity, image systems and optical computers. They are also used as pigment dyestuffs in the dye industry, especially in textile dyeing. Moreover, they are widely used in the perfume. They can be used in aircraft construction, television and computer screens, digital clock displays by taking advantages of the liquid crystal feature that occurs in some metal complexes.
