Summary, etc. <p style="text-align: justify;">Condensation product (<strong>L</strong>) of 5-bromosalicylaldehyde and aminophenol has been synthesised and characterised. Fluorescence of <strong>L </strong>enhances by 23 times on interaction with Ce<sup>3+</sup> while it is quenched completely by Ce<sup>4+</sup>. Ascorbic acid (AA) is a well known strong reducing agent and this property has been used to act <strong>L</strong>:Ce<sup>4+</sup> adduct as a fluorescence “on” sensor for AA. AA reduces Ce<sup>4+</sup> into Ce<sup>3+</sup> and thereby increasing fluorescence of <strong>L </strong>due to the formation of <strong>L</strong>:Ce<sup>3+</sup> adduct. Molecules which generally coexist with AA viz. Cholesterol, Glucose, Sucrose and Dopamine found not to interfere. The interaction of <strong>L </strong>with Ce<sup>3+</sup>, Ce<sup>4+ </sup>and subsequently with AA has been verified with cyclic voltammetry.</p>
