Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 59-48-3, Name is Indolin-2-one, molecular formula is C8H7NO, belongs to indolines-derivatives compound, is a common compound. In a patnet, author is Kumar, Arvind, once mentioned the new application about 59-48-3, Computed Properties of C8H7NO.
A Smartphone-Assisted Sensitive, Selective and Reversible Recognition of Copper Ions in an Aqueous Medium
A photochromic substituted spiropyran (8-methoxy-1,3′,3′-trimethylspiro[chromene-2,2’indoline]) was successfully synthesized and its structural integrity was ascertained using spectroscopic methods. Owing to the uniquely positioned methoxy and phenolic groups for potential coordination with a metal ion, it was investigated for the recognition of toxic metal ions. The spiropyran derivative responded to the presence of Cu2+ ions in an aqueous solution by displaying a color change visible to the naked eye (colorless to pink). The color change was witnessed due to the Cu2+ ion-induced transformation of the closed-form (spiro) of the substituted spiropyran derivative into an open merocyanine (MC) form, which complexes the Cu2+ ion. The color change was further used for the quantification of Cu2+ ion concentration in water using a smartphone captured digital images via pixel intensity analysis. The spiropyran derivative displayed 0.24 +/- 0.01 mu M, 0.65 +/- 0.06 mu M (0.61 +/- 0.06 mu M using paper strips) as the LOD for Cu2+ ions using UV-Visible spectroscopy and digital colorimetry, respectively. The density functional theory (DFT) calculations and Job’s plot supported the formation of a 2 : 1 (H: G) complex between the spiropyran derivative and copper ions. The time-dependent DFT (TD-DFT) investigations were also used to understand the color change during the complex formation, which indicated a good correlation between the experimental and theoretical results at the molecular level.
