Recently I am researching about FLUORIDE-ION; ANION; FLUORESCENCE; AGGREGATION; METALLOGELS; DYE; CHEMOSENSORS; RECOGNITION; VITAMIN-B-6; DERIVATIVES, Saw an article supported by the UGC, New Delhi, IndiaUniversity Grants Commission, India; SERB, DST, New Delhi [EMR/2016/008005/OC]. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Pati, C; Ghosh, K. The CAS is 65-22-5. Through research, I have a further understanding and discovery of 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride. COA of Formula: C8H10ClNO3
A naphthalimide-pyridoxal conjugate 1 has been designed and synthesized. Compound 1 forms a stable greenish yellow colored gel in DMSO:H2O (8:1 v/v). Rheological study reveals that the gel is mechanically strong (G> G) over a wide range of applied strains. The morphology of the gel as determined by FESEM shows a highly cross-linked fibrous network. The gel is anion-responsive and is selectively transformed into a sol with a color change from greenish yellow to deep blue only in the presence of F- among other anions. In CH3CN, compound 1 was also sensitive to basic anions such as F- and AcO- ions. In solution, F- was differentiated from AcO- through a color change. While the yellow colored solution of 1 in acetonitrile was changed into deep blue in the presence of F-, AcO- ions gave a faint blue coloration. A similar colorimetric differentiation of F- from AcO- has been possible in CH3CN by a reusable Schiff base-linked Merrifield resin 1a or 1b.
