The research based on assembly of bulk crystal Metal-Organic Frameworks (MOFs) for nonlinear optics, enantioselective catalysis, and medicine has been extensively carried out1. However, the synthesis and properties of MOFs thin films on self-assembled monolayers (SURMOFs)are still a challenge. Up to now, MOFs (HKUST-1, MOF-2) formed by single ligand and other pillared-layer MOFs (MOF508a, [Cu2(bdc)2dabco]n and [Cu2(ndc)2dabco]n) constructed by mixed ligands on functionalized substrates by employing a step-by-step liquid-phase-epitaxy method (LPE) have been reported2. In previous works chiral linker were used to grow MOFs on substrate and the first example of chiral SURMOF [Cu2(+/-)Cam2dabco]n has been reported in 2012. In this work we grow another chiral SURMOFs [Cu2Cam2bipy]n with highly oriented and homogenous thin film via LPE method3. The potential of chiral SURMOFs for enantioselective adsorption of chiral molecules is studied by quartz crystal microbalance. 1.Shekhah, O.;Wöll, C.,et al. Chem. Soc.
