A new selective fluorescent chemical sensor for Fe3+ based on rhodamine B and a 1,4,7,10-tetraoxa-13-azacyclopentadecane conjugate and its imaging in living cells

A novel system for Fe3+ ion detection based on fluorescence resonance energy transfer

“…Iron deficiency can lead to anemia in the body. However, an excess of Fe 3+ ions causes some types of cancers and deterioration of functions of organs such as heart, pancreas and lungs [2]. Thus, a simple, easy and fast determination of Fe 3+ ions in a liquid media has been accorded signification attention.…”

Design and synthesis of a novel chromium(III) selective fluorescent chemosensor bearing a thiodiacetamide moiety and two rhodamine B fluorophores

“…Therefore, various fluorophores with different excitation and emission wavelengths, such as coumarin [30,31], pyrene [32,33], 1, 8-naphthalimide [34,35], xanthenes [36,37], squaraine [38], cyanine [39], boron dipyrromethene difluoride (BODIPY) [40], and nitrobenzofurazan [41], have been employed to develop various chemical sensors. Among the developed fluorophores, rhodamine and its derivatives [42,43] employ an ideal framework in the construction of fluorescent probes due to their excellent spectroscopic properties including high fluorescence quantum yield, large molar extinction coefficient, and visible wavelength excitation [44][45][46][47]. Based on the principle of metal coordination-induced spirolactam ring-opening of rhodamine, a large number of probes have been reported for the detection of various metal ions, such as Fe 3+ , Hg 2+, Cu 2+ , Sn 4+ , Sn 2+ , Zn 2+ , Pb 2+ , and Cd 2+ [48][49][50][51][52][53][54][55].…”

One step electrosynthesis of conjugated polymers thin film for Fe3+ detection and its potential application

“…However, both its deficiency and excess can cause a variety of diseases in the human body, such as dysfunction of liver [10,11] and kidney [12,13], anemia [14], cancer [15][16][17], Alzheimer's disease [18][19][20], hemochromatosis [21] and Parkinson's disease [22,23]. Therefore, various efficient chemosensors for Fe 3+ detection have gained extensive attentions of scientists.…”
