Abstract:This article epitomizes the design and synthesis of a potential bioactive Semicarbazone Schiff base (E)‐2‐(4‐(diethylamino)‐2‐hydroxybenzylidene)hydrazine‐1‐carboxamide (DHHC) and its water assisted photoinduced tautomerization. DHHC is feebly emissive in non‐polar solvents but the fluorescence intensity intensifies (at 406 nm) in alcohols possibly due to intermolecular H‐bonding. However, in protic polar water, the scenario is markedly different, the fluorescence intensity decreases a bit as compared to alcoh… Show more
