Selective detection of trinitrophenol by a Cd(ii)-based coordination compound

Abstract

A Cd(ii)-based coordination compound, [CdI2(4-nvp)2] (1), has been synthesized using CdI2 and monodentate N-donor ligand 4-(1-naphthylvinyl)pyridine (4-nvp).

A Fluorogenic Triphenyl‐Amine‐Naphthyl‐Hydrazide Probe Selective for Cu2+ and Cysteine Detection via an ON‐OFF‐ON Logic path with Real Applications

“…The condensation of 4,4-Di formylTriphenylamine and1-(hydrazonomethyl)naphthalene-2-ol in 1 : 2 molar ratio synthesizes the probe H 2 L. (Scheme S1). The probe H 2 L shows relatively better solubility in CDCl 3 , so the probe has been well characterized by 1 HNMR and 13 CNMR in CDCl 3 solvent. 1 HNMR (CDCl 3 ) of the probe represents a strongly deshielded singlet peak at 13.440 ppm for the phenolic (À OH) proton.…”

“…The signals from 8.186 to 7.207 ppm represent the protons of aromatic region of the molecule. ( Figure S1) 13 CNMR (CDCl 3 ) of the probe H 2 L includes a signal at 161.13 to 160.79 ppm which corresponds for two imine carbon (CH=N) and phenolic (CÀ OH) peaks. The peaks at 150.01 and 146.28 ppm may be due to CÀ N carbon of triphenyl fragment.…”

“…The details of experimental section, different spectral characterization figures ( 1 HNMR, 13 CNMR, ESI-MS, FT-IR, HPLC) and required additional spectra are included in the corresponding supporting information file.…”

“…Spectrofluorometric method is more convenient and approachable for detection of ions and molecules by qualitative and quantitative analysis owing to their interesting features such as easy modification, simplicity, cost effective and time saving over various known techniques such as redox titration, complexometric titrations, atomic absorption spectrometry, [8] inductively coupled plasma mass spectroscopy (ICPMS), [9] inductively coupled plasma-atomic emission spectrometry (ICPAES), and voltammetry which requires a much more costly and sophisticated management. [10,11] Design of chemosensors aimed at detection of ions and molecules are increasingly drawing attention in different fields of science and technology [12,13] Chemosensors based on Schiff base scaffold with Coumarin, [14][15][16] Rhodamine B, [17][18][19] Fluorescein, [20] Pyrrole, [21] derivatives has been used for Cu 2 + detection.…”

Exploitation of Structure‐Property Relationships towards Multi‐Dimensional Applications of a Paddle‐Wheel Cu(II) Compound

“…[12][13][14][15][16] Recently, the fabrication of coordination compounds that exhibit sensing applications in the detection of ions/molecules becomes another active field of research. [17][18] This application has been established as the active interest in the field of chemistry, physics, chemical engineering, electrical and electronic engineering, and many other branches of technology. The activity of a chemical sensor classically involves the incessant monitoring of the action of a chemical species in a given medium such as solution, blood, tissue, air, drinking water, and waste effluents.…”
