  Acetylenic NIR-chromophores: 2,3-dialkynyl-1,4-diazabuta-1,3-diene complexes of Ni(0) and Ni(II)

  摘要：

  Acetylenic diazabutadienes (DADs) were used to modulate the electron absorption properties of Ni(0) and Ni(II) chelate complexes with respect to those of non-acetylenic DAD metal coordination compounds. Alkynylated bis(N-aryl) DAD ligands are shown to induce efficient metal-to-ligand charge-transfer in coordination compounds of the type (DAD)(2)NI(0). These metal-ligand interactions manifest themselves as intense absorptions in the near infrared (NIR) around 800 nm and are significantly shifted batho- and hyperchromic compared to charge-transfer bands of non-acetylenic DAD metal complexes. Likewise, alkynyl substitution of bis(glyoximato)nickel(II) complexes results in a sizeable absorption band in the visible region of the electromagnetic spectrum. (C) 1999 Elsevier Science S.A.
