Abstract:
Abstract: Schiff bases of fluorescein were synthesized from fluorescein hydrazide using different aromatic aldehydes. These compounds show bright fluorescence different from that of starting material, fluorescein. The compounds were characterised by spectroscopic methods. Absorption and fluorescence spectra of the compounds were also recorded. Keywords: Fluorescein, Schiff bases, Fluorescein hydrazide, fluorescent probes, fluorescence

Abstract:
Two novel isomeric colorimetric probes are established for simultaneous determination of copper ions using 2-hydroxy-5-methoxybenzaldehyde fluorescein hydrazone (5-HMBA-FH) and 2-hydroxy-3-methoxybenzaldehyde fluorescein hydrazone (3-HMBA-FH). They are synthesized by reacting fluorescein hydrazide with 2-hydroxy-5-methoxybenzaldehyde and 2-hydroxy-3-methoxybenzaldehyde, respectively, and then characterized by 1H-NMR, 13C-NMR, and infrared spectrum. The addition of copper ions to the solutions of two novel colorimetric probes can generate the obviously peaks at 498 nm in UV–vis absorption spect

Abstract:
This article discusses the design and analysis of a new chemical chemosensor for detecting mercury(II) ions. The chemosensor is a hydrazone made from 4-methylthiazole-5-carbaldehyde and fluorescein hydrazide. The structure of the chemosensor was confirmed using various methods, including nuclear magnetic resonance spectroscopy, infrared spectroscopy with Fourier transformation, mass spectroscopy, and quantum chemical calculations. The sensor’s ability in the highly selective and sensitive discovery of Hg2+ ions in water was demonstrated. The detection limit for mercury(II) ions was determined

Abstract:
Fluorescein and its various derivatives show remarkable biological and bio-analytical applications because of its solubility, high degree of inertness and high fluorescent activity. To broaden the spectrum of its applications, we synthesized novel fluorescein-based hydrazides (FHJ-0.2 - FHJ-0.6) using different substituted aryl hydrazine. The newly designed and synthesized products have been monitored by thin layer chromatography and characterized by 1HNMR, IR and MS data. To find the application of these hydrazides, the biological screening is considered and screened by antimicrobial and hemo

Abstract:
In this work, we prepared a fluorescein hydrazide-appended Ni(MOF) (Metal–Organic Framework) [Ni3(BTC)2(H2O)3]·(DMF)3(H2O)3 composite, FH@Ni(MOF). This composite was well-characterized by PXRD (powder X-ray diffraction), FT-IR (Fourier transform infrared spectroscopy), N2 adsorption isotherm, TGA (thermogravimetric analysis), XPS (X-ray photoelectron spectroscopy), and FESEM (field emission scanning electron microscopy). This composite was then tested with different heavy metals and was found to act as a highly selective and sensitive optical sensor for the Hg2+ ion. It was found that the aque

Abstract:
The hydrazone functional group is widely applied in several fields. The versatility and large use of this chemotype are attributed to its easy and straightforward synthesis and unique structural characteristics which is useful for different chemical and biological purposes. Recently hydrazone scaffold has been widely adopted in the design of small-molecule fluorescent and colorimetric chemosensors for detecting metals and anions because of its corresponding non-covalent interactions.
