  Synthesis and Optical Properties of Bis(oligophenyleneethynylenes)

  摘要：

  Bis(oligophenyleneethynylenes) 1-4 were prepared as representative members of a new class of potential nonlinear optical materials. The optical properties of 1-4 were examined for evidence of restricted rotation of the aryl rings when compared to their single-strand precursors, which could potentially increase their nonlinear response through more effective conjugation. The effect of altering the electron density of the terminating functional group of these compounds on their properties was also investigated.

  The synthesis of bis(oligophenyleneethynylenes): novel potential nonlinear optical materials

  摘要：

  Various functionalised phenyleneethynylene dimers 10 and trimers 12 were synthesised by palladium-catalyzed Sonogashira methodology. These dimers and trimers were coupled to 1,8-diido-10-methoxyanthracene to generate bis(oligophenyleneethynylenes) 17 and 18. Preliminary results towards the construction of both phenyleneethynylene and phenylenevinylene hybrid motifs are presented. (c) 2005 Elsevier Ltd. All rights reserved.
