ABSTRACT. The Spectral Characterization of (E)-5-(2-phenyldiazenyl)-2-hydroxy benzaldehyde (PDHB)were carried out by using FT-IR, FT-Raman and UV-Vis spectroscopic techniques. All the recorded spectral results were compared with calculated results. The optimization has been performed on the title compound using B3LYP/6-311++G(d,p) level of theory. The optimized bond parameters of PDHB molecule was compared with X-ray diffraction data of related molecule. To study the intra-molecular charge transfers within the molecule the Lewis (bonding) and Non-Lewis (anti-bonding) structural calculation was performed. The Non-linear optical behavior of the title compound was measured using first order hyperpolarizability calculation. In addition of Mulliken atomic charges and thermodynamic properties were also calculated and analyzed.

The Schiff base ligands and their corresponding metal complexes have expanded enormously and include a vast area of organometallic compounds and various aspects of bioinorganic chemistry. On the other hand, azo compounds are very important molecules and have attracted much attention in both academic and applied research. The azo compounds and their metal-azo complexes are extremely used in dyes and data storage. New complexes with metal ions Cu(II) and L are synthesized. Elemental and spectroscopic measurements are used to elucidate the structure of the newly prepared metal complex. The azo-dye Schiff's base behaves as a di-negative N2O2 tetradentate ligand. The metal complexes exhibited square planar structure. The azo-dye Schiff's base and its complex are characterized by FTIR, DRS and EDAX data.

“…These complexes with different structures exhibit diverse spectral characteristics and functionality depending on the arene ligand. Moreover, azo compounds have drawn considerable attention because of their applications in photoelectronics, printing systems, optical storage technology, and photochemistry [24][25][26][27]. Azo compounds, which are connected to organometallic compounds in their structures, possess the properties of both organometallic and azo groups; thus, these compounds can be utilized to produce materials with interesting magnetic, electronic, optic, and anisotropic properties [28][29][30].…”

A D-A-D cationic cyclopentadienyl iron complex containing double arylazo chromophores (Fc-diazo) with methoxyl group (Fc-diazo-OMe) was obtained via nucleophilic substitution and well characterized by IR, UV-visible, 1 H NMR, and 13 C NMR spectroscopy, and MS. UV-Vis absorption and nonlinear optical property of Fc-diazo-OMe were investigated by comparison of Fc-diazo with no methoxyl group (Fc-diazo-H). Quantum chemical calculations of the orbital energy, geometric structure of Fc-diazo-OMe, and Fc-diazo-H were conducted by using density functional methods at the B3PW91/Lanl2dz level. Charge transfer from the highest occupied molecular orbital to the lowest unoccupied molecular orbital was found based on density functional theory. The substitution of the methoxyl group greatly improves the NLO property of Fc-diazo. Fc-diazo-OMe shows effective two-photon absorption, coefficient and third-order nonlinear susceptibility for potential applications as optical materials, while Fc-diazo-H barely shows NLO ability.
