Resumo: A series of complexes trans-[FMo(N=NCHL)(dppe)2][BF4] (L = (bi)thienyl or arylthienyl), were synthesized and fully characterized by 1H, 13C, 31P NMR, IR and UV–Vis spectroscopies. The electronic spectra and electrochemical behavior of the complexes were investigated. The electronic absorption spectra of these complexes display a broad low-energy band in the visible region attributable to metal-to ligand charge transfer (MLCT) transitions. The electron conjugated effect with the heterocyclic nucleus led to a notable improvement of visible light absorption and marked changes in the electrochemical behavior. The hyperpolarizabilities beta of the synthesized compounds were evaluated using the hyper-Rayleigh scattering technique.
