New fluorogenic sensors for Hg2+ ions: through-bond energy transfer from pentaquinone to rhodamine.
New pentaquinone derivatives 5 and 8 having rhodamine moieties have been designed and synthesized that undergo through-bond energy transfer (TBET) in the presence of Hg(2+) ions among the various cations (Cu(2+), Pb(2+), Fe(2+), Fe(3+), Zn(2+), Ni(2+), Cd(2+), Co(2+), Ag(+), Ba(2+), Mg(2+), K(+), Na(+), and Li(+)) tested in mixed aqueous media.
