A fluorescence ratiometric chemosensor for Fe3+ based on TBET and its application in living cells

Fluorescent Chemosensor Bearing Amine and Benzenyl Functionality for Fe3+ Ions Detection in Aqueous Solution

“…Hence, the selectivity of the sensor for metal cations was initially examined in solution 3 OH/H 2 O, 9:1 (v/v), Tris-HNO 3 = 10 mM, pH = 7.0). The fluorescence emission spectra of the A with metal ions were studied.…”

“…Among various transition metals, iron is the most abundant essential trace element in the human body which plays vital roles in many biological processes [1]. Lack of iron in primary stages can cause anemia [2], kidney failure and heart diseases [3] Therefore, the demand for fast detection and selective sensor of Fe 3+ from other ions is important applications in environment and biological systems.…”

A new rhodamine fluorescent OFF-ON-OFF probe for selective sensing of Fe3+ and AcO- in aqueous media and living cells

“…Due to great sensitivity, fluorescent chemosensors combining ionophores and fluorophores are commonly considered superior [8][9][10] . In recent years, rhodamine has been attracted a great deal of attention due to its excellent properties, including good photostability, long emission wavelength, high fluorescence quantum and so on [11][12][13] . However, for the majority of rhodamine fluorescent probes, their anti-interference ability is poor, which are usually chelate with two or more metal ions simultaneously [14] .…”

A novel ratiometric fluorescent probe for detection of Fe3+ by rhodamine–quinoline conjugate

“…Rhodamine and its derivatives are a kind of classic fluorescent dye, which is extensively suitable to act as fluorescent chromophores because of their excellent photo physical properties such as high extinction coefficients, excellent quantum yields and relatively long emission wavelengths in the visible region [16][17][18]. Thus, rhodamine-based probes have been attracting the interest of scientists and widely used to the detection of various metal ions [19][20][21][22]. In general, the design of rhodamine-based probe is based primarily on the ring-opened reaction of the rhodamine spirolactam which is triggered by metal ion.…”
