Three metal-organic frameworks (MOFs) composites with bis(hydrotris(pyrazolyl) borato)iron(II) were synthesized by gas phase diffusion to yield MIL-101(Cr)@[Fe(HB(pz)3)2] ，NH2-MIL-101(Al)@[Fe(HB(pz)3)2] and MIL-100(Al)@[Fe(HB(pz)3)2] composites. The formation， structure and property of products were thoroughly characterized by FTIR、AAS、XRD、and BET measurements. The results showed that, spin crossover complex [Fe(HB(pz)3)2] was confined in the cages of the frameworks MOFs composites, the porous structure developed into a protecting layer and was much more thermal/solvent stable than that of bulk crystalline [Fe(HB(pz)3)2]. The identity of MIL-101(Cr)@[Fe(HB(pz)3)2], NH2-MIL-101(Al)@[Fe(HB(pz)3)2] and MIL-100(Al)@[Fe(HB(pz)3)2], with loading of iron complex at 8.11%, 7.42% and 1.64% respectively, were confirmed by AAS analysis. Finally, color change property of the products were carefully investigated through comparing with pure [Fe(HB(pz)3)2], and the results supported that the three novel MOF-based materials with isolated SCO units could be potentially used as anti-counterfeit packaging materials.
