Five ferrocene-containing metalloporphyrins (Pd-P-Fc, Co-P-Fc, Cu-P-Fc, Zn-P-Fc and Ni-P-Fc) were synthesized and characterized. The crystal structure of Zn-P-Fc determined by using the single crystal diffraction technique belongs to the triclinic system. A typical aggregation of Zn-P-Fc occurs when the concentration of Zn-P-Fc is greater than 2.0 × 10−6 mol/L in solution. The strong interaction between the metalloporphyrin and the ferrocene group was inferred by the absorption spectra, fluorescence spectra and the DFT calculation. Good nonlinear optical properties of these materials were inferred from the low fluorescence quantum yields and the short fluorescence lifetimes. Zn-P-Fc and Pd-P-Fc exhibit great reverse saturable absorption properties for 7 ns laser with 532 nm wavelength, and the β values are 13.36 and 13.41 cm/GW, respectively.
