A Dual-Target Fluorescent Probe with Response-Time Dependent Selectivity for Cd2+ and Cu2+
Journal of Fluorescence - Tập 28 - Trang 1115-1119 - 2018
A novel fluorescent probe (NT) was developed by merging 2-hydrazinylbenzothiazole with 2-hydroxy-1-naphthaldehyde for the detection of Cd2+ and Cu2+. The probe alone is almost nonfluorescent due to the isomerization of C=N in the excited state. The addition of Cd2+ can cause an immediate strong green fluorescence owing to the suppression of C=N isomerization by Cd2+-coordination. Furthermore, NT g......

Graphene Quantum Dots Functionalized with 4-Amino-2, 2, 6, 6-Tetramethylpiperidine-N-Oxide as Fluorescence “Turn-ON” Nanosensors
Journal of Fluorescence - Tập 26 - Trang 2199-2212 - 2016
In this study, we report on the fabrication of simple and rapid graphene quantum dots (GQDs)-based fluorescence “turn-ON” nanoprobes for sensitive and selective detection of ascorbic acid (AA). Pristine GQDs and S and N co-doped-GQDs (SN-GQDs) were functionalized with 4-amino-2,2,6,6-tetramethylpiperidine-N-oxide (4-amino-TEMPO, a nitroxide free radical). The nitroxide free radicals efficiently qu......
Fluorescent Carbon Quantum Dots Functionalized by Poly L-Lysine: Efficient Material for Antibacterial, Bioimaging and Antiangiogenesis Applications
Journal of Fluorescence - Tập 32 - Trang 1789-1800 - 2022
This study illustrates the synthesis of functionalized carbon quantum dots (CQDs) by the one-pot pyrolysis method. The functionalization agent used in CQD synthesis was poly l- lysine (PLL). Various physicochemical techniques were employed to confirm the successful formation of PLLCQD including High resolution transmission electron microscopy (HR-TEM), UV-Vis spectroscopy, fluorescence spectroscop......
New Fluorescent Labels: 4- and 7-Chlorofluorescein
Journal of Fluorescence - Tập 15 - Trang 829-833 - 2005
A new mixture of 4- and 7-chlorofluorescein were synthesized by condensation of resorcinol with 3-chlorophthalic anhydride in the presence of methanesulfonic acid or zinc chloride. These regioisomers were successfully separated by chromatography. The photophysical properties were examined and their absorption and emission maxima at long wavelength, high fluorescence quantum yield, and narrow emiss......
A Novel Water-soluble Ratiometric Fluorescent Probe Based on FRET for Sensing Lysosomal pH
Journal of Fluorescence - Tập 26 - Trang 2079-2086 - 2016
A new ratiometric fluorescent probe based on Förster resonance energy transfer (FRET) for sensing lysosomal pH has been developed. The probe (RMPM) was composed of imidazo[1,5-α]pyridine quaternary ammonium salt fluorophore as the FRET donor and the rhodamine moiety as the FRET acceptor. It’s the first time to report that imidazo[1,5-α]pyridine quaternary ammonium salt acts as the FRET donor. The ......

Novel Rhodafluors: Synthesis, Photophysical, pH and TD-DFT Studies
Journal of Fluorescence - Tập 26 - Trang 2187-2197 - 2016
An efficient protocol for the synthesis of new rhodol derivatives has been developed. The synthesis involves condensation of 2-hydroxy benzophenone derivatives with 1, 3-dihydroxy benzene derivatives in solvents such as ionic liquid (N-methyl-2-pyrrolidonium hydrogen sulfate) and methane sulphonic acid. Both ionic liquid and methane sulphonic acid were found to be promising self-catalyzed solvents......
