Abstract
In this work the chemical properties of the maleic acid C4H4O4 were investigated, through the modeling and molecular reactivity parameters, pH measurements and acid-base equilibrium study using the RAZES 1.0 program, molar conductivity measurements, thermal analysis, uv-visible spectra and oscillator strength to evaluate their potential viability in forming promising complex chemical systems capable of transforming, via inter-system transfer, dispersed electromagnetic radiation into selective light emitting systems or converters of radiation into electricity. It has been observed that the counter-cation of this acid has compatible molecular reactivity parameters for the formation of stable chemical bonds with metal receptors of electrons. Its 2: 1 electrolytic behavior reveals that it can function as a versatile, mono- and / or bidentate chelator, as well as mono- and / or bivalent chelator in the formation of complex adducts. Its thermal stability extends to 100ºC, where it decomposes almost totally to 400ºC under atmosphere of N2, ending with some carbon residue. Their spectra show strong absorption in the ultraviolet region, with the oscillator strength of the order of organic dyes, a property that reflects a careful investigation in the area of research and possible application in promising complex chemical systems.
