A 1 : 2 copper(II) complex of 1-amino-4-hydroxy-9,10-anthraquinone (QH) having the molecular formula CuQ2 was prepared and characterized by elemental analysis, NMR, FTIR, UV-vis mass spectroscopy. The powder diffraction solid complex, magnetic susceptibility ESR spectra were also recorded. presence planar anthraquinone moiety in makes it extremely difficult to obtain a single crystal suitable for X-ray studies. To overcome this problem, density functional theory (DFT) used evaluate an...
In this work, a water-soluble gold nanoparticle-encapsulated polyaniline nanocomposite (AuNP-PANI) was prepared in the presence of an ionic surfactant such as cetyltrimethylammonium bromide (CTAB) using versatile two steps method. The nanoparticles (AuNPs) were characterized by UV–Visible spectroscopy, Transmission Electron Microscope (TEM) and Dynamic Light Scattering (DLS). initially (TEM), Scanning (STEM) DLS. structure composition AuNP-PANI further Fourier Infrared Spectroscopy (FTIR),...
A simple, rapid, selective, and cost-effective colorimetric assay for Cr3+ Eu3+ ion detection has been developed using functionalized gold nanoparticles. Gold nanoparticles (AuNPs) were prepared HAuCl4, where sodium citrate is a reducing agent as well capping agent, then with 1,2,3-triazole-4,5-dicarboxylic acid (TADA). Fourier transform infrared (FTIR) Raman spectroscopies suggested that TADA was on the surface of AuNPs through N atom triazole. The TADA-functionalized (TADA@AuNPs)...
The X-ray diffraction and spectroscopic properties of 1-amino-4-hydroxy-9,10-anthraquinone (1-AHAQ), a simple analogue anthracycline chemotherapeutic drugs were studied by adopting experimental computational methods. optimized geometrical parameters obtained from methods compared with the results analysis two found to be in reasonably good agreement. study, Density Functional Theory (DFT) natural bond orbital (NBO) indicated types hydrogen bonds molecule.

A colorimetric assay has been developed for Zn2+ and homocysteine (Hcy) detection using functionalized silver nanoparticles (AgNPs). AgNPs have synthesized nitrate, where sodium citrate is used as a stabilizing agent NaBH4 reducing agent. Then, the (citrate@AgNPs) were with 1H-imidazole-4,5-dicarboxylic acid (IDCA). UV-visible FTIR spectra suggested that IDCA was on surface of citrate@AgNPs through N atom imidazole ring. The IDCA-functionalized (IDCA@AgNPs) simultaneously detected Hcy from...
Abstract Quantitative polymerization of 4‐vinyl pyridine (4‐VP) and its quaternization has been done simultaneously for the first time in absence organic solvents. 1, 4‐dibromo‐2‐butene acts as quaternizing agent. The quaternized polymer characterized by chemical, thermal spectral analysis. mechanistic path involved elucidated. Particle size, surface area, ion exchange capacity metal binding property were determined. was found to have pH‐dependent chromate with high level selectivity good...
