L. Hauser, Ian R. Colinas, Carolyn Agustin, Andrew S. Ichimura, Scott R. J. OliverWe present a new method in the synthesis
of metal–organic
framework (MOF) thin films using zinc oxide nanowires as the substrate.
This facile method involves growing zinc oxide nanowires on a substrate
(glass, transparent conducting oxide glass, Si wafer), followed by
immersing the nanowire substrate in an iso-reticular metal–organic
framework (IRMOF) precursor solution. The resulting 25 μm thick
film is highly crystalline and covers the entire substrate. Growth
of the IRMOF on the nanowire substrate allows for the film to be used
in potential applications in sensing, membranes, photovoltaics, catalysis,
and gas storage. We have also successfully used microwaves to rapidly
produce these films with comparable film quality to our original method.
