Multinuclear studies of aluminium compounds

Schiff bases and their metal complexes have become well-known for catalytic (e.g., in various synthetic processes) and biological properties (e.g., antifungal, antibacterial, anti-malarial, and antiviral characteristics) since their discovery by Hugo Schiff in 1864. As synthetic compounds, they are employed as versatile tools in numerous applications such as fluorescent turn-on/turn-off sensors for the determination of diverse analytes (e.g., metallic components). As such, they can offer a way to identify toxic ions and/or to provide their speciation in environmental media. This review covers a broad range of Schiff bases that are used in sensing applications for metallic cations and anions in various kinds of environmental and biological media.

A review of the applications of Schiff bases as optical chemical sensors

In this chapter, selected results obtained so far on Fe(III) spin crossover compounds are summarized and discussed Fe(III) spin transition materials of ligands containing chalcogen donor atoms are considered with emphasis on those of N,N-disubstituted-dithiocarbamates, N,N-disubstituted-XY-carbamates (XY=SO, SSe, SeSe), X-xanthates (X=O, S), monothio-β-diketonates and X-semicarbazones (X=S, Se) In addition, attention is directed to Fe(III) spin crossover systems of multidentate Schiff base-type ligands Examples of spin inter-conversion in Fe(III) compounds induced by light irradiation are given

Tris(trifluoro and difluorobutane-2,4-dionato)aluminum(III) complexes

The dipole moments of some nickel(II), copper(II), zinc(II) and cobalt(III) complexes of three new difluoro monothio-β-diketones RCSCH2COCHF2 (R = 2-thienyl, phenyl andp-tolyl) have been determined by static polarization measurements. The mass spectra of these complexes are discussed. The mass spectra of nickel complexes of the correspondingβ-diketones are also presented for the purpose of comparison.
