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.
