A rhodamine-based probe (FS1) was synthesized and its fluorescence properties application to an iron-overloaded cell line demonstrated. FS1 underwent fluorogenic changes by the Fe(3+)-catalyzed reaction, even in presence of other metal cations vitro. Chemodosimeter demonstrated selective sensitive detection intracellular Fe(3+) hepatocytes.
A new chemosensor-based approach to the detection of nitroaromatics is described. It involves analyte-induced quenching excimer emission a dipyrenyl calix[4]arene (L). The chemical and photophysical properties complexes formed between L mono-, di-, trinitrobenzene, di- trinitrotoluene were studied in acetonitrile chloroform by using (1)H NMR, UV/Vis, fluorescence spectroscopy. Fluorescence spectroscopy revealed that trinitroaromatics engendered largest response among various substrates...
A novel calix[4]arene derivative locked in the 1,3-alternate conformation (2) bearing two pyrene and rhodamine fluorophores was synthesized as a selective sensor for Hg2+ ion. The sensoring is based on FRET from excimer emissions to ring-opened absorption upon complexation of Addition mixed solution 2 gave significantly enhanced fluorescence at ∼576 nm via with excitation 343 nm. We also found that formed by intramolecular π−π interactions are more effective obtaining strong bands than those...
Hydrogen storage is crucial in the shift toward a carbon-neutral society, where hydrogen serves as pivotal renewable energy source. Utilizing porous materials can provide an efficient solution, reducing tank pressures to manageable levels and circumventing energy-intensive costly current technological infrastructure. Herein, two highly aromatic frameworks (PAFs), C-PAF Si-PAF, prepared through Yamamoto C─C coupling reaction between trigonal prismatic monomers, are reported. These PAFs...
