The ring-forming polymerization of diacetylenic monomers is very interesting method for the synthesis of conjugated polymer system via an alternating intramolecular–intermolecular chain propagation. Here, we synthesized a new conjugated polymer via the ring-forming polymerization of various dipropargylfluorene derivative by transition metal catalysts. The polymer structure was elucidiated by NMR, IR, and UV-visible spectroscopies. The polymerization proceeded well by various transition metal catalysts to give a high yield of polymer. The spectroscopic studies on the microstructures of polymer indicated that it contains the mixtures of five and six-membered ring moieties. |
