Surface-Modified Gold Nanoparticles Possessing Two-Channel Responsive EuIII /TbIII Cyclen Complexes as Luminescent Logic Gate Mimics.

The development of material-supported molecular logic gate mimics (MGLMs) for contained application and device fabrication has become of increasing interest. Herein, we present the formation of ≈5 nm gold nanoparticles (AuNPs) that have been surface-modified (via a thiol linkage) with heptadentate cyclen-based complexes of europium and terbium for sensing applications using delayed lanthanide luminescence and as integrated logic gate mimics within competitive media.
