Abstract

The aromatic ethers complexes of cyclopentadienyliron (O-CpFe) and aromatic amines complexes of cyclopentadienyliron (N-CpFe) were prepared by coupling several aniline derivatives and phenol derivatives with (η6-chlorobenzene) (η5-cyclopentadienyl) iron hexafluorophosphate through nucleophilic aromatic substitution reaction. The UV/vis absorption, fluorescence, and excitation spectra of the compounds were measured. The abilities of the photoinitiator in photopolymerizing the diglycidyl ether of the bisphenol-A epoxy oligomer under a halogen lamp were evaluated by near-infrared spectroscopy. The results show that the absorption of N-CpFe is higher than that of O-CpFe in the visible region. However, the photoinitiation ability of N-CpFe is lower than that of O-CpFe.
