摘要：

Six new hyperpolarizable chromophores based on functionalized arylthiophene donors and an imidazophenanthroline acceptor moiety have been designed and synthesized for the first time in good to excellent yields by condensation of 5,6-phenantroline-dione with formyl-arylthiophene derivatives in the presence of ammonium acetate in glacial acetic acid. The thermal stability, solvatochromic and nonlinear optical properties of these compounds were evaluated. (C) 2008 Elsevier Ltd. All rights reserved.
