摘要：

Novel 2,2'-bipyridine-based conjugated polymers of formula 2 have been synthesized by Pd-catalyzed cross-coupling reactions between 4,4'-dibromo-2,2'-bipyridine (3) and substituted phenyldiacetylenes (4). The zig-zag arrangement of the 2,2'-bipyridine units implies a helical conformation of 2. The solubility of 2 requires at least a dodecyl side-chain. 2 is thermostable up to 400 degreesC. The polymers have a high fluorescence quantum yield in solution (60%).
