Constitution and Dyeing Properties of a 2:2 Copper Complex Azomethine Dye
A copper(II) complex azomethine dye with 2-(2- pyridylmethyleneamino)phenol (PMAP) ligand was prepared and characterized on the basis of IR, UV/VIS, MS, X-ray and elemental analysis .The structure comprised a dinuclear /Cu_2L_2(O_2CMe)/^+ (L = deprotonated PMAP) cation and the well separated perchlorate anion. Both phenolate residues and the acetate moiety bridged the two copper(II) centres, giving a Cu_2(mi- O)_2(mi-1, 3-MeCO_2) core . The possibility of spectrophotometric determination of copper with this ligand was investigated, as was the possibility of wool dyeing with Cu-PMAP, and the stability of dye-wool bonding at pH=4, 5 and pH=5, 5. The color hue changes on the dyeing samples with a*, b* coordinates (CIELAB diagram) are given.
