Optical Properties of Novel Azo Multi-Functional Dye Thin Films

Extended Abstract By evaluation the practical applicability of new synthesized compounds, starting point represents the thin film optical properties analysis, which provides rich information about chemical bonding, layer thickness, electronic structure, etc. Here, we present optical properties determination of thin nanocomposite films of three novel N-phthalimide azoazomethine dyes containing OH-group at ortho-position in respect to the -CH=Nchromophore group and designed with different electron donating and electron withdrawing substituents. The structure of these previously synthesized by us dyes is shown below.
