Abstract Phenanthroline‐based hexadentate ligands L 1 and 2 bearing two achiral semicarbazone or chiral imine moieties as well the respective mononuclear complexes incorporating various lanthanide ions, such La III , Eu Tb Lu Y metal were synthesized, crystal structures of [ML Cl 3 ] (M=La ) determined. Solvent water molecules act coligands for rare‐earth metals in addition to halide anions. The big Ln ion exhibits a coordination number (CN) 10, whereas corresponding centers with smaller...
β-Cyclodextrin (β-CD) is a nontoxic cyclic oligosachcharide that can encapsulate all or part of organic molecules appropriate size and specific shape through noncovalent interaction. Herein, we report the influence β-CD complex formation an antipyrine derivative on its metal ion sensing behavior. In aqueous solution, shows turn-on fluorescence vanadyl ion, in cyclodextrin medium it senses aluminum ion. The compound unusual quenching binding with β-cyclodextrin (log KSV = 2.34 ± 0.02)....
4-aminoantipyrine is the most widely used analytical reagent for estimation of phenol.Phenolic compounds were determined by buffering sample to a pH 10.0 and adding produce yellow or amber colored complex in presence ferricyanide ion.The colour intensified through extraction into chloroform.Measurement this quantitatively determines phenol concentration sample.In review, we discuss usage as identification phenolic present any samples reported.This review focuses on use sensing studies from...
A dye-sensitized solar cell (DSSC) is a sandwich type consisting of photoelectrode, counter electrode and liquid electrolyte. The photo comprises titanium dioxide semiconducting thin film grown over glass substrate which in-turn has transparent conducting layer tin oxide doped with fluorine (FTO) coated it. aim this work to develop photoelectrodes different dyes increase the efficiency cells. Dyes obtained from fresh sources maqui, black myrtle, spinach dye mixture spinach-maqui-myrtle were...
Sr-doped ZnO nanoparticles have been synthesized using a soft chemical method. The doping ratio of Sr is varied in the range 0 at.%, 3 and 5 at.% to 7 at.%. X-ray diffractograms revealed that samples had hexagonal (wurtzite) structure without trace any mixed phase. average crystallite size (NPs) ranged from 39 46 nm. was increased for initial (3 at.%) ions, further increase reduced particle due some distortion produced lattice. surface morphology NPs were investigated FESEM (Field Emission...
On-off switching and molecular logic in fluorescent molecules are associated with what chemical inputs can do to the structure dynamics of these molecules. Herein, we report a naphthalene derivative, fashion its binding β-cyclodextrin DNA, operation possible using protons, cyclodextrin, DNA as inputs. The compound crystallizes out keto-amine form, intramolecular N-H⋅⋅⋅O bonding. It shows stepwise formation 1:1 1:2 inclusion complexes β-cyclodextrin. aminopentenone substituents encapsulated...
We report for the first time green synthesis of silver nanoparticles using West Indian cherry (Malpighia emarginata) extract known its high vitamin C content. UV–visible spectroscopy, powder X ray diffraction (PXRD), dynamic light scattering (DLS), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDX) analysis were used to characterise nanoparticles. Silver thus synthesised exhibit antimicrobial activity against gram-negative bacteria such as Pseudomonas aeruginosa,...
