Metal-organic frameworks (MOFs) hold promise as separation membranes due to their tunable permeation properties enabled by the structural diversity stemming from the plethora of available metal/organic linker combinations. Although relatively rapid progress for highly selective MOF membranes has been achieved, reliable and scalable thin film processing remains a challenge. In this talk, I will discuss synthesis and post-synthesis modification methods we have been developing based on vapor phase processing and use of electron-beam-, X-ray- and plasma-induced modifications. These methods establish a new materials processing paradigm with potential uses beyond thin film separation membranes.
