Abstract

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 RuII-EuIIIheterobimetallic complexes, K{[RuII(tBubpy)(CN)4]2EuIII(H2O)4} (wheretBubpy = 4,4′-di-tert-butyl-2,2′-bipyridine). Synthesis, X-ray crystal characterization, and spectroscopic properties of this RuII-EuIIIheterobimetallic complex were reported. Binding properties of the RuII-EuIIIcomplex 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 RuII-EuIIIcomplex 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.
