Abstract

Metal complex azo dyes are more light-stable and allow for easier control of the wavelength through selection of suitable substituted group. Recently, azo metal chelates have been given increasing attention as some results of their fascinating geometrical and electronic properties which inform the possibility of their application in molecular memory usage. This research work aimed at synthesis of metal complex dyes using certain transition metal complexes as Ligand. Metallic salts of Co2+ and Cu2+ were dissolved in distilled water and appropriate amount of NaOH and Methanol were added to chelating agents. The mixture was heated to 80-900C in a mantle for a specific period of time. The product obtained was filtered using filter paper and the residue dried in an oven for 35minutes. The percentage yield of the dried residue (metal orange II complex) was determined and physical properties such as colour, texture, solubility and melting point of the complexes were analysed using FTIR and UV-Vis spectrometric techniques. The maximum wavelength of absorption for all the three metals complexes synthesized occurred between 483.5nm and 550nm. Similarly, their frequencies of vibration also occur relatively similar peaks along their respective frequency bands. These suggest the fact that the metal orange II complexes synthesize possesse similar structural formulae. The preparation of such metal complexes for both industrial and laboratory uses should be encouraged.
