The title of the article was 《Facile synthesis of the chemically oxidative grafted copolymer of 2,6-diaminopyridine (DAP) and thiophene (Th) for optoelectronic and antioxidant studies》.Electric Literature of C5H7N3 The author mentioned the following in the article:
The current preliminary investigation presents for the first time the synthesis of grafted copolymer Poly (DAP-g-Th) from 2,6-diaminopyridine (DAP) and thiophene (Th) via chem. oxidative copolymerization using ferric chloride as an oxidizing agent for enhancing its photoluminescence properties. Modifications via copolymerization were confirmed by optical, morphol., and spectral anal. through FT-IR, UV-Visible, XRD, fluorescence studies. Increased value of oscillator strength, molar extinction coefficient, and lowered bandgap were observed in the case of poly(DAP-g-Th). FT-IR results showing alteration in the properties of polymer lying intermediate between individual monomers confirming copolymerization Intermediate quantum yield value disclosing transformations in the electronic structure of the poly(DAP-g-Th). Morphol. studies also suggested the intermediate property of copolymer. Poly(DAP-g-Th) showed the best antioxidant activity against DPPH free radical assay and its IC50 value was reported 0.024 ± 0.001 mg/mL. The results came from multiple reactions, including the reaction of 2,6-Diaminopyridine(cas: 141-86-6Electric Literature of C5H7N3)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Electric Literature of C5H7N3
