Synthesis of a Conjugated Cyclopolymer by the Ring-Forming Polymerization of 9,9-Difluorofluorene by the Homogeneous Palladium Catalysts and the Characterization of Polymer Properties |
| 초록 |
A conjugated polymer, poly(9,9-dipropargylfluorene), was prepared by the cyclopolymerization of 9,9-dipropargylfluorene by (Bicyclo[2.2.1]hepta-2,5-diene)dichloropalladium(II) in high yield. Poly(9,9-dipropargylfluorene) showed characteristic UV-visible absorption band at 307 and 324nm and violet-blue PL spectrum at 411 nm, corresponding to a photon energy of 3.01 eV. The cyclic voltamograms of the polymer exhibited reversible electrochemical behaviors between the doped and undoped peaks. It was found that the kinetics of the redox process of polymer is controlled by the diffusion process mixed with the electron transfer process from the experiment of the oxidation current density of polymer versus the scan rate. |
