“…Fig. 1 shows that the absorbance of the complex in the CTAC reversed micellar solution decreases down to zero, indicating a gradual dissociation of the complex with the passage of time, although the absorbance maximum of the iron(II) complex is almost the same as reported earlier in water (522 nm) [18]. The first order rate constants for the dissociation reaction were obtained by analyzing the decline in the absorption band of [Fe(bpy) 3 ] 2+ .…”

Tris(2,2'-bipyridine) complex of iron(II) was found to cause an increase in the chemiluminescence (CL) emission of luminol dispersed in the reversed micellar medium of cetyltrimethylammonium chloride (CTAC) in 1:1 (v/v) dichloromethane-cyclohexane/water, when the iron(II) complex in dichloromethane was mixed directly with the reversed micellar solution containing luminol. Visible absorption measurements showed that, when dispersed in the CTAC reversed micellar medium, the iron(II) complex dissociates easily. In the reverse micelle, subsequently the free iron(II) ion produced may catalyze the CL oxidation of luminol even in the absence of hydrogen peroxide. The CL emission produced under the optimized experimental conditions was detectable at a minimum iron(II) concentration of 1.0 x 10(-9) M using a flow injection system.

“…Sensing anions is an important technological challenge in the context of environmental pollution such as eutrophication of rivers, [87] carcinogenesis arising due to metabolites of nitrates [88] etc. Besides various approaches based on specific anion receptors, [89] supramolecular gels have been exploited to sense anions either via phase separation or photoresponse [90, 91] .…”

Real‐time Observation of Macroscopic Helical Morphologies under Optical Microscope: A Curious Case of π–π Stacking Driven Molecular Self‐assembly of an Organic Gelator Devoid of Hydrogen Bonding

Supramolecular assemblies such as tubules/ helix/double helix/helical tape etc. are usually submicron objects preventing direct observation under optical microscope. Chiral-pure form of these assemblies is important for potential applications. Herein, we report a rare phenomenon wherein a DMSO gel of a simple terpyridine derivative [(4-CNPhe)4PyTerp] produced macroscopic helical morphologies (μm length scale) which could be observed under optical microscope, formation of which could be monitored by optical videography, stable enough to withstand acidic vapour, robust enough to display reversible gel $ sol in response to acidic and ammonia vapour and sturdy enough to be maneuvered with a needle. These properties appeared to be unique to the title compound as the other related derivatives failed to display such assembly structures. SXRD and MD simulation studies suggested that weak interactions (π-π stacking) played a crucial role in the self-assembly process.

The compound 1,2-cyclohexanedione dioxime, nioxime, is similar to dimethylglyoxime in yielding scarlet and yellow precipitates with nickel and palladium, respectively, which can be used for the gravimetric determination of these metals. It is soluble in water in contrast to dimethylglyoxime, so that its use is theoretically unaccompanied by danger of contaminating the precipitates with excess reagent or of solubility loss by the addition of alcohol. On the other hand nioxime is a more powerful reducing agent than dimethylglyoxime, and this introduces some complications in its use.
