title: Fabrication of oriented silver-functionalized RPM3 films for the selective detection of olefins.
abstract: Oriented thin films of a flexible, luminescent, metal organic framework (MOF), [Zn2(bpdc)2(bpee)·2DMF] (bpdc = 4,4'-biphenyldicarboxylate; bpee = 1,2-bipyridylethylene), also known as RPM3, were prepared on glass via pulsed laser deposition (PLD) followed by a solvothermal treatment. RPM3 thin films were then functionalized with AgNO3 by forming a π complex with the bpee linker. The reversible binding of olefins such as propylene and 1-hexene to the Ag(+) functionalized RPM3 thin film was monitored by fluorescence spectroscopy. Adsorption of the olefins resulted in a fluorescence enhancement, while the corresponding paraffins either did not change or partially quenched the fluorescence. The RPM3 thin films hold promise as olefin sensors or adsorbents for olefin/paraffin separations.
