Development of fluorescent FeIII sensor based on chalcone

Experimental and theoretical study: Determination of dipole moment of synthesized coumarin–triazole derivatives and application as turn off fluorescence sensor: High sensitivity for iron(III) ions

“…Therefore selective and sensitive determination of iron in biological and environmental systems is very essential. However there are only limited fluorescence chemosensors [44][45][46][47] available for detection of Fe 3+ ions in various systems with their own merits and demerits. So there is a need to develop simple and selective fluorescence sensors for detection of Fe 3+ ions in various systems.…”

Fluorescence detection of iodide anion using a donor–acceptor (D–A) thiourea derivative

“…4(a) showed the small fluorescence changes at a pH range of 6-8. The emission intensity decreased dramatically when the pH value was lower than 5, which was attributed to the protonation of dimethylamino [51], destroyed the donor-acceptor system. So, the ICT fluorescence disappeared.…”

Luminescent properties of chalcone and its aminoderivatives

“…Chalcone and its derivatives are widely used as fluorescent probes [20,21], materials with significant nonlinear responses [22] and typical chromophore components for photochemical sensors [23]. Charge transfer character of the low-lying ππ ⁎ transition from the phenyl ring to the polyene chain allows one to vary the energy of the intense transition introducing substituents in the phenyl ring [9].…”
