CHEMOSPHERE 2024; 363:142841. [PMID: 39004148 DOI: 10.1016/j.chemosphere.2024.142841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 07/09/2024] [Accepted: 07/11/2024] [Indexed: 07/16/2024]
Abstract
Herein, two poly(3-aminocarbazole) derivatives containing imidazole N-type acceptor were synthesized and reported, which are named PCPI and PCBI respectively. The fluorescence spectrum shows that PCPI (Em = 498 nm) and PCBI (Em = 398 nm) both have a strong fluorescence emission. It is worth noting that PCPI has a larger stokes shift of 153 nm, which is beneficial for improving the sensitivity of the sensor and enhancing its anti-interference ability. As expected, our experimental results indicate that both PCPI and PCBI can cause a specific response of "fluorescence OFF" to Hg2+ compared with other ions. And PCPI and PCBI both have excellent detection capabilities for Hg2+, with detection limits of 69.8 nM and 11.4 nM respectively. Moreover, PCBI exhibits excellent absorption of Hg2+ with a maximum absorption capacity of 477.8 mg/g at 20 °C. It indicates that PCBI can be used as a functional material for the detection and removal of Hg2+ in water.

Unveiling the ion sensing capabailities of 'click' derived chalcone-tailored 1,2,3-triazolic isomers for Pb(ii) and Cu(ii) ions: DFT analysis. RSC Adv 2024; 14:15374-15390. [PMID: 38741961 PMCID: PMC11089528 DOI: 10.1039/d4ra01471e] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 05/07/2024] [Indexed: 05/16/2024] Open
Abstract
In this study, two novel chalcone-derived 1,2,3-triazole-appended positional isomers (probe 6 and probe 9) were synthesized via the 'CuAAC' (Cu(i) - catalysed alkyne azide cycloaddition) methodology for the purpose of metal ion detection. The synthesized probes underwent characterization utilizing standard spectroscopic methodologies including FTIR, NMR (1H and 13C), and mass spectrometry. Subsequently, the sensing capabilities of these probes were explored using UV-Vis and fluorescence spectroscopy, wherein their selective recognition potential was established for Pb(ii) and Cu(ii), both of which can pose serious health hazards when prevalent in the environment above permissible limits. Both the probes exhibited fairly low limits of detection (LoD), determined as 5.69 μM and 6.55 μM in the case of probe 6 for Pb(ii) and Cu(ii) respectively; whereas the probe 9 exhibited an LoD of 5.06 μM and 7.52 μM for Pb(ii) and Cu(ii), respectively. The job's plot for the probe demonstrates the formation of a 1 : 1 complex between the metal and ligand. Furthermore, the interaction of the free probes with the metal ions in the metal-ligand complex was elucidated through 1H NMR analysis and validated theoretically using Density Functional Theory (DFT) simulations with the B3LYP/6-311G++(d,p) and B3LYP/LANL2DZ basis sets for geometry optimization of the probes and their corresponding metal complexes. These findings offer a reliable approach to Cu(ii) and Pb(ii) ion detection and can be further used for the potential applications in environmental monitoring and analytical chemistry.

SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 302:123163. [PMID: 37478755 DOI: 10.1016/j.saa.2023.123163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 07/10/2023] [Accepted: 07/15/2023] [Indexed: 07/23/2023]
Abstract
The present report describes the application of the 'Click Chemistry' pathway to synthesize a fluorescent probe (APT) based on ampyrone (4-aminoantipyrine), entailing two benzyl groups as the fluorophores coupled to the antipyrine structure through 1,2,3-triazole moieties. Infrared spectroscopy (IR), nuclear magnetic resonance (1H and 13C), and mass spectrometry were the standard spectroscopic methods used to characterize APT. The ion recognition potential of the probe was analyzed through absorption and emission spectroscopy employing a 4:1 combination of CH3CN and H2O, which demonstrated APT to be an efficient sensing agent for Cu(II) ions, wherein the absorption spectrum of the probe displayed a hypsochromic shift with a hyperchromic shift on gradually adding the metal ion solution of Cu(II), whereas quenching of the probe's fluorescence emission on Cu(II) addition was attributed to the chelation-enhanced fluorescence quenching (CHEQ), induced by the d9 electronic configuration of Cu(II). The stoichiometry of the complexation of APT with Cu(II) is indicative of a 1:1 ratio, while the detection limit (LOD) and quantification limit (LOQ) as estimated from the fluorescence titration results were 3.11 µM and 10.35 µM respectively. Furthermore, DFT analysis was also undertaken to yield the energy-optimized structures and HOMO-LUMO density plots of APT and its corresponding Cu(II) complex via the B3LYP/631G+(d,p) level of theory for APT, and LANL2DZ basis set for the APT-Cu(II) complex. Docking analysis of the probe with the synaptic vesicle protein (SV2A) gave glimpses about its anticonvulsant properties.

RSC Adv 2023; 13:32399-32412. [PMID: 37928840 PMCID: PMC10623384 DOI: 10.1039/d3ra05760g] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Accepted: 10/30/2023] [Indexed: 11/07/2023] Open
Abstract
Herein, a 1,2,3-triazole derivative (CBT), synthesized using the Copper(i) catalyzed Alkyne Azide Cycloaddition (CuAAC) procedure, based on a chalcone skeleton has been reported, that was implemented as an effective sensor for Pb(ii) and Cu(ii) ions. The synthesized CBT was characterized using spectroscopic techniques such as FTIR, NMR (1H and 13C), and mass spectrometry. The sensing behaviour of CBT was analyzed using UV-Vis spectroscopy, demonstrating selective sensing for Pb(ii) and Cu(ii) ions, competitively. The correlation plot revealed the detection limit for Pb(ii) and Cu(ii) ions to be 100 μM and 110 μM respectively. In addition, DFT simulations and molecular electrostatic potential (MEP) studies scrutinized the binding strategy of the free CBT and its orientation towards the metal ions in the metal-ligand complex. The probe CBT was predicted via the online platform Way2drug for its pharmacological properties, investigating the possibility to inhibit early atherosclerosis. CBT was subsequently docked to the TRIB1 protein using AutoDock Vina and demonstrated a high binding affinity with a value of -6.2 kcal mol-1.

Abstract
The most recent and advanced class of crystalline and permeable compounds are covalent organic frameworks (COFs). Due to their exceptional qualities, such as their porous structure, high surface area, strong chemical and thermal stabilities, low density, good water stability, luminescent nature, and so on, COFs have seen remarkable growth over the past ten years. COFs have been successfully researched for a number of applications based on these characteristics. The current state of COFs has been reported in this study, with particular attention paid to their design, topology, synthesis, and a variety of biological applications, including drug delivery systems, photodynamic and photothermal therapy, biosensing, bioimaging, etc. Moreover, several miscellaneous applications, such as catalysis, gas storage and separation, photocatalysis, sensors, solar cells, supercapacitors, and 3D printers, have also been explored. It is significant that we have examined current research on COFs with a focus on the biological applications, which are infrequently covered in the literature. Descriptions of the difficulties and prospective outcomes have also been given.
