Abstract
In the present study a series of azo dyes: 5-((4-pentyloxyphenyl)azo)-salicylaldimine-N-R (R = phenyl, 4-methoxyphenyl, cyclohexyl) and related copper(II) bis chelates have been synthesized and characterized by IR, NMR, mass spectroscopies and elemental analyses. The thermal stability of free ligands and related copper(II) bis(chelate) was studied by using differential scanning calorimetry (DSC) and thermogravimetric analyses (TGA). The differences in the thermal stability were related to the structure of free ligands and copper complexes and decomposition products were characterized according to their X-ray diffraction pattern.
