Conjugated polymers arylene-ethynylene

Sanechika, K. Yamamoto, T. Yamamoto, A. Palladium catalyzed C-C coupling for synthesis of re-conjugated polymers composed of arylene and ethynylene units. Bull. Chem. Soc. Jpn. 1984, 57(3), 752-755. [Pg.215]

Palladium-catalyzed cross-coupling is a powerful tool for the synthesis of various 7c-conjugated molecules and polymers through sp and sp carbon-carbon bond formation [17-20]. Scheme 3 shows the synthetic routes for poly (p-arylene-ethynylene)-type (PAE-type) jc-stacked polymers by Sonogashira-Hagihara cross-coupling [21, 22]. Polymer 13 was obtained from the monomers pseudo-para-dibromo[2.2]... [Pg.153]
