“…This class of dyes was established as an alternative to more expensive anthraquinone dyes. 173,174 The thiophene containing azo dyes have many advantages including a color deepening effect as an intrinsic property of the thiophene ring and small molecular structure leading to better dye ability. 175,176 Increasing the electron-withdrawing strength of the substitutents on the thiophene ring resulted in batochromic shifts.…”

Chemistry of 2-aminothiophenes is arguably one of the most extensive and dynamic field of present-day thiophene research. Since 1961 when first report on the Gewald reaction was reported it became a universal method for synthesis of substituted 2-aminothiophenes and has gained prominence in recent times. The availability of reagents and the mild reaction conditions all contribute to the versatility of this reaction. This review summarizes the synthetic strategies for substituted 2-aminothiophenes. Consequently, details about the proposed mechanism of Gewald-like reactions and the wide scope of substituted 2-aminothiophenes for real life applications.

“…Azo compounds have received much structural interest in chemistry due to their versatile applications in many different areas such as polyester fiber [1], disperse dyes [2], as well as their use in many biological reactions and in analytical chemistry [3]. Furthermore, their application as industrial dyes and in biological systems where some may be used as inhibitor for tumor growth [3] is of great importance.…”

The molecular and crystal structures of the title compound, C 16 H 18 N 2 O, were characterized and determined by single crystal X-ray diffraction method in addition to spectroscopic means such as IR, UV-VIS and 1 H NMR. The compound crystallizes in orthorhombic space group P bca, with a = 9.3350(5) Å , b = 23.4878(13) Å , c = 26.5871 (12) Å , Z = 16, D calc. = 1.1591(1) g/cm 3 , l (MoK a ) = 0.073 mm -1 . Monomers of the compound in the crystal structure are linked into C(7) and C(8) chains generated by translation along the [1 0 0] direction with the aid of O-HÁÁÁN type H-bonds which serve to the stabilization of periodic organization of the molecules beside major and minor component in the disordered azo fragment. In order to describe conformational flexibility and the crystal packing effects on the molecular conformation, potential barriers regarding the rotation along both Ar-N bonds were calculated by varying the related torsional degrees of freedom in every 10°ranging from -180°to +180°via quantum chemical calculations at DFT/B3LYP level.

“…These dyes have been exploited for non-linear optical usage when they contain substituent groups on the aromatic rings with push-pull electron ability [6]. Azo dyes have excellent thermal and optical properties and widely applied in areas such as optical recording medium [7], toner [8], inkjet printing [9] and oil soluble light fast dyes [10].…”
