Abstract
A chemodosimeter Ph2P(LS)NP(–S–CH2–anthracene)Ph2 (L1), featuring the methylanthracenyl moiety covalently linked to one of the two S atoms of an S,S9-tetraphenyldithioimidodiphosphinate (L) unit exhibited good selectivity and sensitivity for Hg2+ in an aqueous environment. The chemical reaction involved differs from those reported in the literature for other Hg2+ chemodosimeters: the binding of Hg2+ induces the cleavage of the PS–CH2 bond to form the stable neutral complex [HgL2] and an emissive anthracenyl derivative. The X-ray crystal structure of L1 is reported (CCDC number 919620).
