“…4 Therefore metal complexes of Schiff bases attained a prominent place in coordination chemistry, which was shown over many years by the large number of publications 5 and by the comprehensive reviews. 6,7 In view of the above mentioned importance of Schiff bases and their complexes and due to the fact that few reports are known in the literature regarding photochemical 8 and thermal behaviour [9][10][11] of Schiff base complexes, we performed photolysis and thermogravimetric studies on Cu II -complexes of N-salicylideneaniline and its derivatives (I) as a continuation of our previous interest in this respect.

Cu II -complexes of N-salicylideneaniline and its derivatives were not light sensitive in most solvents such as acetonitrile. A photo-decomposition occurred upon irradiation in halocarbon solvents such as CHCl 3 . It has been suggested that such photoreactivity is attributed to the reactivity of charge-transfer to solvent (CTTS) excited state attained upon irradiation. A mechanism has been proposed to account for the results obtained. The complexes have been thermally analysed in nitrogen and static air using thermogravimetry (TG) and derivative thermogravimetry (DTG). The thermal degradation of the complexes proceeds in two or three stages. The kinetic parameters obtained from the Coats-Redfern and Horowitz-Metzger equations show the kinetic compensation effect.

“…Non-isothermal decomposition of the metal complexes under study resembles the reaction A (s) B (s) + C (g) (11) which can be studied kinetically. The kinetic studies were carried out making use of two different procedures: the Coats-Redfern 27 and the Horowitz-Metzger 28 methods.…”
