RBAP, a Rhodamine B-Based Derivative: Synthesis, Crystal Structure Analysis, Molecular Simulation, and Its Application as a Selective Fluorescent Chemical Sensor for Sn2+

Abstract

Abstract:A new fluorescent chemosensor based on a Rhodamine B and a benzyl 3-aminopropanoate conjugate (RBAP) was designed, synthesized, and structurally characterized. Its single crystal structure was obtained and analyzed by X-ray analysis. In a MeOH/H 2 O (2:3, v/v, pH 5.95) solution RBAP exhibits a high selectivity and excellent sensitivity for Sn

A new Rhodamine B-based ‘on–off’ chemical sensor with high selectivity and sensitivity toward Fe3+ and its imaging in living cells

“…[32][33][34][35] On the basis of this interpretation, researchers have synthesized a series of rhodamine derivatives that can be used as fluorescence turn-on chemosensors for the detection metal ions, such as Hg 2+ , Cu 2+ , Sn 2+ , Cr 3+ , Sn 4+ and Pb 2+ . [36][37][38][39][40]26,41,42 Although, many rhodamine based sensors for Fe 3+ have been reported, 43,44 only few of them have been applied in biological systems for the detection of Fe 3+ . 45,46 Due to the paramagnetic nature of Fe 3+ ions, the majority of fluorescent chemosensors for Fe 3+ are fluorescence quenchers, [47][48][49] which certainly hinder fluorescence imaging in vivo and in situ monitoring.…”

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

“…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]. However, only a few Cr 3+ selective fluorescent sensors have been reported for monitoring Cr 3+ due to the paramagnetic nature of Cr 3+ ions [56][57][58].…”

New room temperature coacervation scheme for lead traces determination by solid surface fluorescence. Application to wines produced in Argentina

“…Rhodamine dye is characterized as a highly selective and sensitive fluorescence probe for metals [29][30][31][32][33]. In order to study the fluorescent response of RhB in presence of In order to assure quantitative retention of RhB-Pb(II) system, several filtering material were tested.…”
