Abstract:
Plasmachemical deposition is a substrate-independent method for the
conformal surface functionalization of solid substrates. Structurally well-defined pulsed
plasma deposited poly(1-allylimidazole) layers provide surface imidazole linker groups for
the directed liquid-phase epitaxial (layer-by-layer) growth of metal−organic frameworks
(MOFs) at room temperature. For the case of microporous [Zn (benzene-1,4-
dicarboxylate)-(4,4′-bipyridine)0.5] (MOF-508), the MOF-508a polymorph containing
two interpenetrating crystal lattice frameworks undergoes orientated Volmer−Weber
growth and displays CO2 gas capture behavior at atmospheric concentrations in proportion to the number of epitaxially grown MOF-508 layers.
