| Abstract: | A new monomer (2-N,N-dimethylamino-4,6-bis(2-furan)-pyrimidine) was synthesized and its homopolymer was successfully prepared by using ferric
trichloride as an oxidant. The structure of monomer and polymer were fully characterized by 1H-NMR, FT-IR, UV, fluorescent spectroscopy, and X-ray diffraction. The N,N-dimethylformamide solution of the polymer showed a UV-Vis peak at 387 nm and the PL spectrum gave a peak at 517 nm. We have
observed that the polymer was sensitive to inorganic acids and the protonation behavior was investigated applying inorganic
acids such as HCI and H2SO4. The corresponding UV-Vis peaks were observed at 464 and 357 nm, respectively. X-ray diffraction data shows that polymer
had a certain crystalline region. The polymer exhibited an η] value of 0.21 dl/g at 25 °C in H2SO4 (w=98 %). |
