Maimaitiyiming, Xieraili; Shi, Caijin published their research in Materials Chemistry and Physics in 2021. The article was titled 《Poly(1,4-diethynylphenylene-4,6-pyrimidine)s for fluorescence detection of mercury(II) ion》.Category: pyrimidines The article contains the following contents:
A series of alternating conjugated polymers (poly (1,4-diethynylphenylene-4,6-pyrimidine) (PI) and poly (2,5-diheptyloxy-1,4-diethynyl-phenylene-4,6-pyrimidine) (PII) were synthesized via Sonogashira coupled reaction. Chem. structure of conjugated polymers were certified by NMR and FT-IR. The PIII(poly(2,5-bis(dodecoxy)-1,4-diethynyl-phenylene-4,6-pyrimidine) previously reported by our group to illustrate the application of such polymer. The fluorescence of PIII were efficiently quenched when introduced I-, the specificity of the polymer for I- was verified by experiments and detection limit reaches 5.19 x 10-7 mol/L. Thanks to the high association constant between Hg2+ and I-, the fluorescence of PIII/I- system recovered with the addition of Hg2+. The detection limit of Hg2+ reaches ∼4.92 x 10-6 mol/L for PIII/I- complex system. PIII/I- could act as high selective, sensitive and anti-interference optical probe for Hg2+. In the part of experimental materials, we found many familiar compounds, such as 4,6-Dichloropyrimidine(cas: 1193-21-1Category: pyrimidines)
4,6-Dichloropyrimidine(cas: 1193-21-1) is a member of organic chlorides. Almost all organochlorine compounds are synthesized. It is widely used as intermediates, solvents and pesticides of chemical synthetic products.Category: pyrimidines
