Pyridoxal-based low mol. weight progelator 1 has been designed and synthesized for the selective visual detection of Ag+ ions through sol-to-gel conversion. Compound 1 shows excellent gelation property with desired gel stiffness only in the presence of Ag+ ions over a series of other metal ions in 1 : 1 (volume/volume) aqueous solvent system miscible with organic solvents such as DMSO, DMF, and dioxane, and validates the visual detection of Ag+ ions. The gel properties were studied by FTIR, UV-Vis, SEM (SEM), and rheol. measurements. Min. gelation concentration was found to be 3 mg mL-1. While Ag+-induced metallogel in DMSO/H2O is thermally reversible, it is irreversible in the DMF/H2O system. The model compound 2, devoid of hydroxyl groups, did not show gelation under identical conditions and established the role of pyridoxal moiety in 1. In addition, compound 1 exhibits the selective sensing of Hg2+ ions over a series of metal ions in the solution phase, as established by UV-Vis, fluorescence, and 1H NMR studies. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Name: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride).
3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Name: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride
