“…According to our previous studies of heterobimetallic donor−acceptor coordination complexes, M A C≡NM B (M A = Fe II , Ru II , and Os II ; M B = Pt II , Cu II , and Ni II ), it is envisioned that heterobimetallic complexes with different donor−acceptor combinations can produce specific sensing properties toward different kinds of analytes. In this case, Eu(III) acceptors are well-known hard Lewis acids which have a general strong affinity to hard bases such as nitrogen-containing molecules.…”

“…Rapidly detecting these amines in their vapor form and reporting the signal in a naked-eyed manner are particularly important. Our group has focused on the feasibility of using M A C≡NM B heterobimetallic coordination complexes as chemodosimetric compounds (M A = Fe II , Ru II , and Os II ; M B = Pt II , Cu II , and Ni II ) for the detection of various analytes . With suitable metal ion combinations, it is envisioned that chemodosimeters with fine-tuned analyte specificity can be obtained.…”

Gaseous biogenic amines such as putrescine, spermidine, aniline, and trimethylamine are important biomolecules that play many crucial roles in metabolism and medical diagnostics. A chemodosimetric detection assay has been developed for those gaseous amines by Ru(II)-Eu(III) heterobimetallic complexes, K{[Ru(II)((t)Bubpy)(CN)(4)](2)Eu(III)(H(2)O)(4)} (where (t)Bubpy = 4,4'-di-tert-butyl-2,2'-bipyridine). Synthesis, X-ray crystal characterization, and spectroscopic properties of this Ru(II)-Eu(III) heterobimetallic complex were reported. Binding properties of the Ru(II)-Eu(III) complex with common gases revealed that this complex is very selective to gaseous amine molecules. Sensitivity of this complex toward the amines was found as ∼log k() = 4.5-4.8. Real time monitoring of gaseous biogenic amines was applied to real fish samples (Atlantic mackerel) by studying the spectrofluorimetric responses of the Ru(II)-Eu(III) complex toward different biogenic amine concentration. GC/MS studies were also used as a reference for the studies. A linear spectrofluorimetric response was found toward biogenic amine concentration in real fish samples. This complex was found to respond specifically to those biogenic amines down to 10 ppb.

The detection of neutral biogenic amines plays a crucial role in food safety. Three new heterobimetallic Ru(II)-Ln(III) donor-acceptor complexes, KPrRu, KNdRu, and KSmRu, K{[Ru((II))((t)Bubpy)(CN)4]2-Ln((III))(H2O)4} (where (t)Bubpy = 4,4'-di-tert-butyl-2,2'-bipyridine), have been synthesized and characterized. Their photophysical and X-ray crystallographic data were reported in this study. These complexes were found to be selective for biogenic amine vapors, such as histamine, putrescine, and spermidine, with a detection limit down to the ppb level. The sensitivities of these complexes to the amines were recorded as ~log K = 3.6-5.0. Submicron rods of the complexes, with a nanoscale diameter and microscale length, were obtained through a simple precipitation process. Free-standing polymeric films with different degrees of porosity were fabricated by blending the submicron rods with polystyrene polymer. The polymer with the highest level of porosity exhibited the strongest luminescence enhancement after amine exposure. Real time monitoring of gaseous biogenic amines was applied to real fish samples (Atlantic mackerel) by studying the spectrofluorimetric responses of the Ru(II)-Ln(III) blended polymer film.
