The synthesised push-pull systems have been studied by electrochemistry, UV/Vis and IR spectroscopy and nonlinear optical properties have been calculated. Moreover, quantitative relationships between the measured and calculated properties and the structural features have also been evaluated. Electrochemical and spectral properties have mainly been affected by the presence of strongly conjugating acceptors, large pi-linkers and the spatial arrangement of the chromophore.
