State-of-the-Art, Insights, and Perspectives for MOFs-Nanocomposites and MOF-Derived (Nano)Materials. [PDF]
Adv MaterDifferent approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

The Crystal Structure of 1-(2-Thiazolylazo)-6-bromo-2-naphthol [PDF]
Bulletin of the Chemical Society of Japan, 1976 Abstract The crystals of 1-(2-thiazolylazo)-6-bromo-2-naphthol are orthorhombic, with a space group of P212121, and with unit-cell dimensions of a=19.044(3), b=31.996(9), c=4.221(1) Å, and z=8. The crystal structure was solved by the heavy-atom method and refined by the least-squares technique to give an R value of 0.064 for 1608 ...

Use of 1-(2-thiazolylazo) 2-naphthol in rapid determination of iron in geological matrices [PDF]
Talanta, 1994 The present work describes the use of 1-(2-thiazolylazo)-2-naphthol (TAN) as a spectrophotomeric reagent for iron determination. TAN reacts with iron(II) forming a brown complex with absorption maximum at 575 and 787 nm. The following parameters were studied: complex stability, pH effect, amount of the TAN, buffer selection, amount of acetate buffer ...

Rapid Spectrophotometric Determination of Chromium(III) with 1-(2-Thiazolylazo)-2-naphthol in Presence of Surfactant [PDF]
Bulletin of the Chemical Society of Japan, 1985 Abstract Chromium(III) reacts with 1-(2-thiazolylazo)-2-naphthol at 80–95°C in acid media (pH 5.7), in presence of benzoate and sodium dodecyl sulfate. Presence of surfactant increases sensitivity of the complex and reduces heating time to 5 min, thus giving rise to perhaps the most rapid method for absorptiometric determination of ...

THE MOLECULAR STRUCTURES OF PALLADIUM(II), COPPER(II) AND NICKEL(II) CHELATE OF 1-(2-THIAZOLYLAZO)-2-NAPHTHOL [PDF]
Chemistry Letters, 1974 Abstract The structures of palladium(II), copper(II) and nickel(II) chelate of 1-(2-thiazolylazo)-2-naphthol have been determined by X-ray analysis. The coordination configuration around the metal atom has been found to be square-planar, square-pyramidal and octahedral for palladium, copper and nickel, respectively.
