Flavonol based alkynyl ruthenium complexes devoted to the detection of metal traces in solution are described. The sensitivity of both absorption and emission properties of the 3-hydroxyflavone unit as a receptor for the metal cations, and of an alkynyl ruthenium moiety as an extended pi-conjugated system, provides an efficient molecular sensor for rapid, sensitive and selective detection of lead(II) cations.
