Abstract
Palladium compounds such as Pd(PPh3)4 and Pd(OAc)2 catalyze polycondensation between dihalo aromatic compounds, X–Ar–X (Ar=p-phenylene, 2,5-thiophenediyl, 9,10-anthracenediyl, 2,6-pyridinediyl, p-benzenedicarbonyl, p-xylene-α,α′-diyl), and acetylenic compounds (p-C6H4(C≡CH)2 or p-C6H4(C≡CMgBr)2). The polymers obtained have high thermal stabilities and most of them show fluorescence. One of the polymers is converted into semiconductors by doping with electron acceptors.Keywords
