  Synthesis and properties of azonaphtharylamide pigments having arylamide groups at 2- and 7-positions

  摘要：

  We studied two azonaphtharylamide pigments having arylamide groups at the 2- and 7-positions on the naphthol ring. Presence of the 7-substited amide group distinguishes the pigments from conventional azonaphtharylamide pigments derived from 3-hydroxy-2-naphthoic acid. The 7-substituent caused a hyperchromic effect but did not produce bathochromic shift in the optical absorption spectra in solution compared with the corresponding 7-unsubstituted counterparts. Molecular geometry optimizations through semi-empirical MO calculations showed that extent of the chromophore systems in the pigments with and without the 7-substituent is nearly the same, which is consistent with absence of the bathochromic shift. The MO calculations also showed that the MOs localized in the 7-substituents are involved in the electronic transitions in the longest wavelength bands of the pigments, which is responsible for the hyperchromic effect. The 7-substituted pigments exhibited better resistivity to light and heat than the 7-unsubstituted ones. (C) 2014 Elsevier B.V. All rights reserved.
