Abstract:
The precise alignment of multiple layers of metal-organic framework (MOF) thin films, or MOF-on-MOF films, over macroscopic length scales is presented. The MOF-on-MOF films are fabricated by epitaxially matching the interface. The first MOF layer (Cu2 (BPDC)2 , BPDC=biphenyl-4,4'-dicarboxylate) is grown on an oriented Cu(OH)2 film by a "one-pot" approach. Aligned second (Cu2 (BDC)2 , BDC=benzene 1,4-dicarboxylate, or Cu2 (BPYDC)2 , BPYDC=2,2'-bipyridine-5,5'-dicarboxylate) MOF layers can be deposited using liquid-phase epitaxy. The co-orientation of the MOF films is confirmed by X-ray diffraction. Importantly, our strategy allows for the synthesis of aligned MOF films, for example, Cu2 (BPYDC)2 , that cannot be grown on a Cu(OH)2 surface. We show that aligned MOF films furnished with Ag nanoparticles show a unique anisotropic plasmon resonance. Our MOF-on-MOF approach expands the chemistry of heteroepitaxially oriented MOF films and provides a new toolbox for multifunctional porous coatings.
