SENSOR FOR MONITORING AN ANALYTE

摘要

A food spoilage sensor of the general formula wherein M is a transition metal ion; D₁, D₂, D₃ and D₄ can be the same or different and can be N or P; R¹ and R², R³ and R⁴, R⁵ and R⁶, and R⁷ and R⁸ can be the same or different and from, taken together with the adjacent carbon atoms to which they are bonded and joined together, an aromatic or a cyclic group with at least one of the aromatic or cyclic groups possessing one or more polymerizable moieties. The complex selectively binds biogenic amines which are released by food spoilage microorganisms and undergo a detectable color change upon exposure thereto.
