Five cationic mixed-ligand Ni(II) complexes with 2,2?-dipyridylamine (dpamH) and substituted salicylaldehydes (X-saloH), having the general formula [Ni(dpamH)2(X-salo)](NO3), were prepared and characterized by physicochemical and spectroscopic techniques (FT-IR and UV?vis) and their interaction with calf-thymus (CT) DNA and serum albumins was investigated. The complexes are formulated as [Ni(dpamH)2(3-OCH3-salo)](NO3)·CH3OH, 2, [Ni(dpamH)2(5-CH3-salo)](NO3)·CH3OH, 3, [Ni(dpamH)2(5-NO2-salo)](NO3)·CH3OH, 4, [Ni(dpamH)2(5-Cl-salo)](NO3), 5 and [Ni(dpamH)2(5-Br-salo)](NO3), 6. Moreover, in the absence of dpamH, one neutral nickel-salicylaldehydato complex was also prepared and characterized as [Ni(5-NO2-salo)2(CH3OH)2], 1. The structures of complexes 2 and 4 were verified by X-ray crystallography. The thermal stability of the complexes was examined by the simultaneous thermal analysis technique (TG/DTG-DTA). Spectroscopic (UV?vis), electrochemical (cyclic voltammetry) and physicochemical (viscosity measurements) techniques were employed in order to study the binding mode and binding strength of the complexes to CT DNA, while ethidium bromide (EB) displacement studies (performed by fluorescence emission spectroscopy) revealed the ability of the complexes to displace the DNA-bound EB. Intercalation is the most possible mode of interaction of the complexes with CT DNA. The interaction of the complexes with albumins was studied by fluorescence emission spectroscopy and the determined binding constants present relative high values.

In the chromate oxidation of a partially acylated sugar derivative to form the corresponding uronic acid, acyl migration to the primary alcohol group is a frequent cause of interference.In contrast to more commonly employed ester substituents, the O-levulinoyl group is far less prone to migration during oxidations with Jones reagent (chromic-sulfuric acids).Examples described here include levulinoyl at O-5 of acyclic and furanose derivatives, and both eq and ax O-4 of pyranose derivatives.It is also shown that, because of the acidity of the Jones reagent, use of the O-levulinoyl group, in combination with a primary p-anisyldiphenylmethyl substituent, permits sequential rapid hydrolysis of the latter and oxidation of the newly exposed alcohol group, which favors high overall yields.In contrast to its immobility in these oxidation reactions, when the leulinoyl group is on O-2 of an aldosyl bromide, it participates in 1,2-orthoester formation as rapidly as O-acetyl.The 2,3,4,6-tetraacetate of either anomer of methyl D-glucopyranoside is oxidized to a uronic acid in moderate yield, by chromic acid in 5:1 acetic acid-water.

Multidisciplinary research on organic fluorescent molecules has been attracting great interest owing to their potential applications in biomedical and material sciences. In recent years, electron deficient systems have been increasingly incorporated into fluorescent materials. Triarylboranes with the empty p orbital of their boron centres are electron deficient and can be used as strong electron acceptors in conjugated organic fluorescent materials. Moreover, their applications in optoelectronic devices, energy harvesting materials and anion sensing, due to their natural Lewis acidity and remarkable solid-state fluorescence properties, have also been investigated. Furthermore, fluorescent triarylborane-based materials have been commonly utilized as emitters and electron transporters in organic light emitting diode (OLED) applications. In this review, triarylborane-based small molecules and polymers will be surveyed, covering their structure-property relationships, intramolecular charge transfer properties and solid-state fluorescence quantum yields as functional emissive materials in OLEDs. Also, the importance of the boron atom in triarylborane compounds is emphasized to address the key issues of both fluorescent emitters and their host materials for the construction of high-performance OLEDs.
