These compounds were both prepared from 1-phenylvinyl-ferrocene and 5,5-dimethyl-1,3-cyclohexanedione under catalysis of manganese(III) acetate according to the radical addition mechanism. The prominent spectroscopic data of the target stereoisomers were provided by FT-IR, LC-MS, (1) H NMR, (13) C NMR techniques, and their stereochemical identification was made primarily by NOESY analysis. The corresponding data (absorbance, transmittance and optical and transport energy gap) were collected from UV-vis studies. The optical properties of the glass slides coated with E-FerCycAc and Z-FerCycAc films were examined and consequently, the optical and transport energy band gap values of the E-FerCycAc were found significantly lower than Z-FerCycAc. The physicochemical and spectroscopic findings (HOMO-LUMO energies, bandgap values, UV-vis, FT-IR, (1) H, and (13) C NMR spectra) were also compared and supported with the acquired DFT calculations.eninfo:eu-repo/semantics/closedAccessFerrocene derivativesE-Z stereoisomerismFilm coatingOptical conductivityDFTArticle8945245910.1016/j.optmat.2019.01.0722-s2.0-85061545074Q1WOS:000465509800064Q1
