Electro-optical and electrochemical properties of Poly(9,9-dipropargylfluorene) |
| 초록 |
For many years, considerable research efforts have been dedicated to various types of conjugated polymers because of their extraordinary electronic and optical properties. Here, a conjugated cyclopolymer, poly(9,9-dipropargylfluorene), was prepared by the cyclopolymerization of 9,9-dipropargylfluorene by various transition metal catalysts. 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 vs the scan rate. This polymer showed characteristic UV–vis absorption band at 307 and 324 nm and violet-blue PL spectrum at 411 nm, corresponding to a photon energy of 3.01 eV. |
