| Abstract: | A series of novel conjugated polymers containing bifluorenylidenes units was synthesized under mild conditions with W(CO)6 as the catalyst, and the repeated units of the polymers were linked at 9 position of fluorine by the double bond. The new polymers represent narrow band gap, and the maxium absorption of polymer P1 in film is peaked at 710 nm. In most cases, the conjugated polymers containing fluorenes units show strong photoluminescence(PL) emission, while the synthesized polymers show no photoluminescence(PL) emission. The synthesized polymers contain new backbone structure. Their optical and electrochemical properties were studied in detail. |
