This article reports a convenient supramolecular strategy to construct fluorescent photoswitchable molecular assemblies between macrocyclic host, cucurbit[8]uril (CB8), and fluorogenic dye, thiazole orange (TO). The interaction mechanism the stable stoichiometric host-guest arrangements have been claimed on basis of optical absorption, steady-state time-resolved fluorescence lifetime anisotropy measurements, also geometry optimization studies. CB8 recognized TO in its 2:2 stoichiometry...
Outfitted with numerous coordination and hydrogen bonding sites, nucleotides represent a class of naturally occurring ligands for metals leading to both hard soft materials wide range applications. Reported herein, new multistimuli-responsive metal–organic hydrogel through the spontaneous self-associative complexation inosine 5′-monophosphate (IMP) Ag(I) ions in aqueous medium. The strong optically transparent hydrogels were formed without aid any external influences such as heating/cooling...
Three 1D coordination polymers (CPs) [M(pdca)(H2O)2]n (M = Zn, Cd, and Co; 1–3), a 3D framework {[(CH3)2NH2][CuK(2,3-pdca)(pa)(NO3)2]}n (4) (2,3-pdca pyridine-2,3-dicarboxylate pa picolinic acid), have been synthesized adopting solvothermal reaction strategy. The CPs thoroughly characterized using various spectral techniques, that is, elemental analyses, FT-IR, TGA, DSC, UV/vis, luminescence. Structural information on 1–4 was obtained by PXRD X-ray single-crystal whereas morphological...
A new fluorescent sensor <bold>5</bold> having fused imidazopyridine scaffold has been synthesized <italic>via</italic> cascade cyclization. It exhibits highly sensitive and selective detection of Fe<sup>3+</sup> (<italic>‘turn-on’</italic>) Hg<sup>2+</sup> (<italic>‘turn-off’</italic>) <italic>in vitro</italic> in HeLa cells.
Ba 0.5 Sr Co x Fe 1-x O 3-δ (BSCF) has garnered considerable attention as a promising catalyst for the alkaline oxygen evolution reaction (OER). However, intrinsic roles of and at active sites during...
A multichannel, ultrasensitive and selective receptor (<bold>1</bold>) has been developed for practical detection of Hg<sup>2+</sup>in various drinking waters.
A π-conjugated fluorescent probe, thiophene-2-carboxylic acid{5-[(thiophene-2-carbonyl)-hydrazonomethyl]thiophen-2-ylmethylene}hydrazide (1), comprising a thiophene–thiophene conjugate, has been designed, synthesized, and characterized by elemental analysis, FT-IR, 1H 13C NMR, ESI-MS techniques. The presence of N-, O-, S-atoms enables 1 to be good cation-chelating agent. Probe is highly selective ultrasensitive toward detection biologically crucial heavy transition-metal ions Zn2+, Cd2+,...
We review problems raised by Fe II emission in AGNs and address the question of its relationship to other broad-line region (BLR) lines. The self-shielding, stratified, BLR model Gaskell, Klimek & Nazarova (2007; GKN) predicts that comes from twice radius H$\beta$, agreement with widths lines being only 70% H$\beta$. This disagrees some reverberation mapping results which have suggested H$\beta$ arise at similar radii. highest quality mapping, however, supports predictions suggest lower is...
A rare earth concentrate assaying about 60% Y2O3, is generally obtained directly from Y rich minerals like xenotime or monazite after preliminary fractionation of earths chloride as practised currently at Indian Rare Earths Ltd.. Alwaye. Using this intermediate concentrate. SX process has been developed in our laboratory to purify (>99.9%) presence NH4SCN. The parameters for DEHPA and PC 88A systems have optimised using a computer program BASIC. flowsheet tested bench-scale produce several...
Dimeric Cu(<sc>ii</sc>)-complex developed from disulfane ligand, serves as dual-channel metalloreceptor for Fe<sup>3+</sup>/Ca<sup>2+</sup>and detection of Fe<sup>3+</sup>in real water samples.
Mercury is considered as a highly toxic and widespread heavy-metal pollutant. In the present work, two flat-sheet polymer sorbents have been synthesized for selective preconcentration of mercury from natural waters. These are silver nanoparticle (AgNP)-embedded poly(acrylamide)-grafted poly(propylene) sheet (Ag-PAM-PP) 1,8-octanedithiol-functionalized gold-coated (HS-octyl-S-Au-PP). The functional groups acrylamide thiol provide binding sites Hg2+ ions; whereas nanoparticles reduce to Hg0 it...
Abstract Two ferrocenyl (Fc) derivatives Fc‐benzimidazopyridine ( 5 ) and Fc‐pyrroloquinoxaline 6 have been synthesized through an inexpensive metal‐free approach via tailoring the reaction conditions. X‐ray single crystal analysis revealed that same reactants in presence of different reagents condition afforded structurally distinct products . Markedly, act as fluorescent probes for Fe 3+ discrete signalling with high selectivity ppb level sensitivity. Based on fluorescence changes, Job's...
A couple of 2-aminoethylpyridine based fluorescent compounds (E)-1-((2-(5-nitropyridin-2-ylamino)ethylimino)methyl)naphthalen-2-ol (1) and (E)-4-nitro-2-((2-(5-nitropyridin-2-ylamino)ethylimino)methyl)phenol (2) have been designed synthesized by setting up reactions N-(2-aminoethyl)-5-nitropyridin-2-amine with 2-hydroxy-1-naphthaldehyde 2-hydroxy-5-nitrobenzaldehyde, respectively. Both the probes characterized elemental analyses, FTIR, 1H & 13C NMR, UV/vis fluorescence spectral techniques....
