Mamtimin, Xirali published the artcileSynthesis, characterization and acidochromism of Poly(2-N,N-dimethylamino-4,6-Bis(2-thienyl)-pyrimidine), SDS of cas: 56-05-3, the publication is Journal of Polymer Research (2011), 18(1), 105-109, database is CAplus.
A new monomer (2-N,N-dimethylamino-4,6-bis(2-thienyl)-pyrimidine) was synthesized and its homopolymer was successfully prepared by using Ferric trichloride (FeCl3) as an oxidant. The structure of the polymer and monomer was fully characterized by 1H-NMR, FTIR, UV-vis, Fluorescent spectroscopy and X-ray diffraction pattern. The polymer gives rise to a band at λ max = 391 nm. The polymer showed the PL spectrum, gave a peak at 507 nm. We have observed that the polymer was sensitive to inorganic acids and the acidochromism behavior was investigated applying organic acid such as CF3COOH. The corresponding UV-Vis peaks were observed at 464 nm and 357 nm resp. X-ray diffraction data shows that polymer has a certain crystallinity. The polymer exhibited an [η] value of 0.26 dLg-1 at 25° in H2SO4 (w = 98%).
