The title of the article was 《Colorimetric Detection of Fe(II) and Co(II) by Using Terpyridine-Based Derivative》.Related Products of 112881-51-3 The author mentioned the following in the article:
A multi-ion chromogenic sensor based on a terpyridine moiety was developed for the semiquant., visual, and sensitive speciation anal. of Fe2+ and Co2+ ions in water. Each metal ion exhibited a different color, and significant color evolution was observed by the naked eye, resulting in semiquant. visual detection. A smartphone was used for visual detection by identifying the RGB values of the probe solutions The application of smartphones shortened the detection time dramatically and reduced the detection cost. This method provides a new strategy for the semiquant. detection of heavy metal ions in water samples. In the experiment, the researchers used many compounds, for example, 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3Related Products of 112881-51-3)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Related Products of 112881-51-3 Pyridine has a conjugated system of six π electrons that are delocalized over the ring.
