Condensation Product of 5-Bromosalicylaldehyde and Amino Phenol: Fluorescence Sensor for Ascorbic Acid and AND Logic Gate
Keyword(s):
Abstract Condensation product of 5-bromosalicylaldehyde and aminophenol (L) has been synthesised and characterised. Fluorescence of L enhances by 23 times on interaction with Ce3+ while it is quenched completely by Ce4+. Ascorbic acid (AA) is a well known strong reducing agent and this property has been used to act L:Ce4+ adduct as a fluorescence “on” sensor for AA. AA reduces Ce4+ into Ce3+ and thereby increasing fluorescence of L due to the formation of L:Ce3+ adduct. Molecules which generally coexist with AA viz. Cholesterol, Glucose, Sucrose and Dopamine found not to interfere. The interaction of L with Ce3+, Ce4+ and subsequently with AA has been verified with cyclic voltammetry.
