Lithium-induced supramolecular hydrogel

We describe a novel anisotropic supramolecular gel made of cyclodextrin-dye, in which physical gelation is completed by lithium salt. Rheological experiment reveals the elastic behaviors of the hydrogel, and high ionic conductivity represents a good mobil

Colorimetric sensing of Cu2+ using a cyclodextrin-dye rotaxane

A dye rotaxane having 8-hydroxyquinoline as coupling component was prepared in the presence of α-cyclodextrin and its structure identified using NMR. The dye rotaxane displayed high color strength regardless of the solvent used and responded to changes in pH based on tautomeric equilibrium, without any interference by the cyclodextrin macrocycle. Compared to the non-rotaxanated forms, the dye rotaxane displayed a characteristic spectral response to the presence of Cu2+ which was attributed to the formation of?a polymeric, metal-dye rotaxane complex which was of high solubility because of the presence of cyclodextrin. Thus, this approach can clearly be used as a facile and efficient sensor for copper ions.

Studies on Pollutants: Spectrophotometric Determination of Nitrile as "Azoxine Dye"

Ten new reagent systems for determination of nitrile in water have been studied.A new system for the determination of nitrile using diazotised aromatic amine with 8-hydroxyquinoline as a coupling reagent has been developed.Sulphanilide was found to be most suited out of the ten amines tried for the determination of nitrite.The λmax of the dye is 500 nm.The Beer's law is followed in the range of 4-30 μg of nitrite per 25 ml.The molar absorptivity and Sandell's sensitivity are 30 x 1E3 litre mole-1 cm-1 and 0.0015 μg cm-3 respectively.The optimum reaction conditions and other analytical parameters such as, Beer's law, sen sitivity and interferences due to foreign species have been studied.
