Liquid-phase epitaxial growth of a homochiral MOF thin film on poly(L-DOPA) functionalized substrate for improved enantiomer separation.

A homochiral MOF film grown on a functionalized substrate in a capillary column with high orientation and homogeneity was successfully prepared by using a layer-by-layer liquid phase epitaxial method; by introducing self-polymerized 3,4-dihydroxy-L-phenylalanine (poly(L-DOPA)) as a chiral substrate, the obtained enantiopure substrate mounted homochiral MOF thin film showed improved enantiomer separation.
