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
摘要合成并表征了五种含二茂铁的金属卟啉(Pd-P-Fc,Co-P-Fc,Cu-P-Fc,Zn-P-Fc和Ni-P-Fc)。通过单晶衍射技术测定的Zn-P-Fc的晶体结构属于三斜晶系。当溶液中Zn-P-Fc的浓度大于2.0×10-6 mol / L时,会发生典型的Zn-P-Fc聚集。通过吸收光谱,荧光光谱和DFT计算推断出金属卟啉与二茂铁基团之间的强相互作用。从低的荧光量子产率和短的荧光寿命推断出这些材料的良好的非线性光学性质。Zn-P-Fc和Pd-P-Fc对波长为532 nm的7 ns激光显示出很好的反向饱和吸收特性,其β值分别为13.36和13.41 cm / GW,
