Rezumat:

The electrochemical study some azo-azulene compounds (Az-N=N-Y,where Y = substituted phenyl,pyridine,thiazole) was performed by cyclic and differential pulse voltammetry as well as rotating disk electrode methods in order to find their electrochemical properties and to establish the influence of donor and acceptor substituents on the behaviour of azulene and azo groups. Calculations
were performed by using quantum mechanics based methods to correlate the electrochemical reactivity with the structure. Good correlations between the experimental oxidation and reduction potentials and the calculated ionization potentials and LUMOs have been found.
