Article Description

Selective and quantitative measurement of aqueous nitrate (NO) anion is achieved using solid [Pt(Cl-4-tpy)Cl]ClO salt (Cl-4-tpy = 4-chloro-2,2′:6′2′′-terpyridine), and as the salt supported on controlled porous glass. This detection method relies on the color change of the Pt(ii) complex from yellow to red and intense luminescence response upon ClO exchange with NO due to concomitant enhancement of Pt⋯Pt interactions. The spectroscopic response is highly selective for NO over a large range of halides and oxoanions.
