Donor atom selective coordination of Fe³⁺and Cr³⁺trigger fluorophore specific emission in a rhodamine–naphthalimide dyad

Abstract

A rhodamine–naphthalimde dyad capable of discerning Fe3+and Cr3+ions in aqueous samples is synthesized and its application in live cell imaging is demonstrated.

An anthracene based fluorescent probe for the selective and sensitive detection of Chromium (III) ions in an aqueous medium and its practical application

“…The spectroscopic response of ANT-Th was quite fast (<1 min), and complete saturation was observed after 5 min ( Figure S3). Comparison of the ANT-Th with some other Cr 3+ sensitive fluorescent probes (Table S1) [22,24,[33][34][35][36][37][38][39][40][41][42] clearly shows the superiority of this method. The LOD value of ANT-Th was lower than the other Schiff bases based fluorescent probe, as indicated in Table S1 [22,34,36,41,42].…”

One-dimensional chiral copper (II) complexes with novel nano-structures and superior antitumor activity

“…generally used for cell viability and inhibition ratio assay. The MTT assay is a popular method which measures the activity of enzymes that can reduce the MTT reagent to purple formazan dye [42,43]. Briefly, A-549, Bel-7402, HCT-8 and CCC-HEL-1 (10 4 cells/well) cells were seeded in each well of 96-well cell culture plate and maintained at 37 °C humidified incubator with 5% CO2 for 24 h. Next day, the cells were incubated with complex 1, 2, 5-Fu (at various concentrations 0.005 -5 μg ml -1 respectively) and 3 (5 μg ml -1 ) for 48 in the case of cancerous cell lines (A-549, Bel-7402, HCT-8).…”

5-Hydroxymethylfurfural modified rhodamine B dual-function derivative: Highly sensitive and selective optical detection of pH and Cu2+

“…To the best of our knowledge, a hugely limiting factor of the above rhodamine B probes is that they can detect only the same kind of analytes using fluorescence and UV-Vis absorption spectrometry method at the same time. Furthermore, although dual-function fluorescent chemosensors designed for detecting different metal ions are plentiful [54][55][56][57][58], for pH and metal ions using different optical signals are relatively few [59].…”
