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.
