Condensation of primary amine including sulfonilic acid group and anthraquinone compounds, synthesis of Fe(III), Cr(III), Co(II) complexes and invastigation of their photochromic properties

Coupling and diazo compounds were synthesized by using 1-amino-4-bromo-2-methyl anthraquinone and the primer amines components such as 2-amino benzene sulfonilic acid and aniline p-vinyl sulfonilic acid in presences of s-triazine ring. The metal complexes of the synthesized ligands were achieved with Co(II), Fe(III), Cr(III) metal salts. The characterizations of all the synthesized compounds were determined by using UV-visible, FT-IR, 1H NMR, 13C NMR, AAS, magnetic susceptibility and elemental analysis techniques. Their photochromic properties have been investigated and the synthesized complexes when exposed to UV light are less sensitive than their ligands in terms of photochromism.
